Portable charger power bank 10000 mah
Both models under consideration Chinese manufacturer Xiaomi, very popular and even fashionable nowadays, are not among the “hot” new products, however, among the considerable number of external batteries (power banks) that we have visited, we have not yet encountered samples of this brand, so we started working with them with considerable interest.
Mi Power Bank Pro 10000
Information support, characteristics, equipment
Unfortunately, at the time of testing there was no description of the model in the Russian-language section of the company’s website, so we used information from the global website.
True, there is a slightly different model index - PLM01ZM, and we got PLM03ZM, but perhaps the difference is only in the orientation towards certain regional markets, which is also hinted at next fact: the instructions in the copy we received were in Chinese, as were the inscriptions on the packaging.
You can also visit the official one, where there is a fairly complete set of information in Russian, and you can also download Russian-language instructions (the translation is not perfect, but quite decent). True, such an index is not indicated there at all.
There are slight discrepancies in the information provided in these two sources and on the packaging, but they do not relate to the significant features of the model.
The packaging box is designed without any frills, but a “tax stamp” is glued to it: if you rub it with a coin or a fingernail in a gray square, you will see a 20-digit authentication code, by which you can check the authenticity of the product on the company’s official website. What to do if there is no confirmation is a separate question.

We have already said more than once that the off-system unit “amp-hour” can often be misleading, especially when compared: the capacity in ampere-hours is the same for a tiny power bank battery and a hundred times larger and heavier UPS batteries. And this is not a matter of technology, it’s just that in relation to electric batteries and batteries it is better to talk about the energy they store in watt-hours, which also takes into account the voltage they provide.
IN in this case on the packaging and on the case two energy values are given: for the lithium-polymer battery itself 38.5 Wh and reduced to a 5-volt output, which is used by the connected loads, but again using an off-system unit: “7100mAh 5.0V” . In terms of calculation, this gives an energy of 35.5 Wh - less than that of a battery, because voltage conversion cannot occur without losses, which in this case are not too large: the efficiency is 92%, in the descriptions a close value of 93% is found , and we will see what actually happens during testing.
The power bank claims to have protection against high voltage and overload (input and output), short circuit, recharge and deep discharge. Also noted is the use of a positive battery temperature coefficient(battery PTC), and here it is necessary to clarify: this is a set of technological measures aimed at producing lithium-ion battery cells with increased security when used in conditions other than normal. Probably, it is the presence of PTC that explains such wide temperature ranges of charge and especially discharge declared for this model.
Appearance, operating features
The power bank is made in a flat dark gray aluminum case with lighter plastic caps on the ends; no other colors are currently offered. True, in the "Gallery" official online store Two color options are mentioned, but apart from the designations (“grey 3” and “grey 4”), we did not find any difference in the photographs provided.
The thickness of the walls of the case is about 0.5 mm - it is impossible to measure more precisely without opening it, and no one gave us sanctions for such an action. The rigidity is quite high, and the resistance to mechanical stress is clearly higher than that of plastic cases.
Available at English-language resource materials speak of double anodizing, which can be considered a clear hint at the special durability of the coating. In addition, it mentions “CNC edge” (or “CNC-finished edges”); Perhaps the English-speaking reader will understand this abbreviation immediately, but we will explain: this means that the edges of the aluminum part of the body are processed on a CNC machine, and indeed, they have small neat chamfers, polished to a shine, which are absent from the next (cheaper) participant review.
The thickness and other dimensions roughly correspond to those of a modern smartphone, the screen diagonal of which is about 5 inches, that is, holding a “sandwich” of these two gadgets connected by a charging cable with one hand will be quite convenient. But we must take into account that one device may well scratch another, and it is better to equip one of them (or both) with a case, fortunately for the Mi Power Bank Pro 10000 such accessories are quite accessible, and in a wide range.
The cable is the only thing included. Its length is small, just under 20 cm from connector to connector, and in the aforementioned “sandwich” it will not be a very disturbing part. Another thing is that for other ways of mutual placement of a mobile device and a battery (for example, the first in the hand, the second in the chest pocket), as well as in some cases of connecting to a charger, such a cable may be too short.
At one end of the case there are only inscriptions, including those explaining the main parameters, and the connectors, along with controls and displays, are concentrated on the opposite.
There are two connectors: USB A(f) output and Type-C, used to recharge the power bank’s own battery. For universal connections, the supplied cable has a completely normal USB A(m) connector at one end, and a Micro-USB connector at the other end plus an adapter to Type-C, connected by a flexible leash that will prevent the adapter from getting lost.
On the one hand, it is very convenient, but on the other hand, you will have to carry this cable with you all the time or take care of purchasing such accessories in stock: there is not yet an abundance of cables with Type-C either in household supplies or in offices. In addition, you need to be careful: the connector and adapter connected together create a double lever compared to a single connector, that is, it will be easier to pull them out of the input port by accidental and careless action (or even break something).
By the way, some descriptions talk about a flat USB-Micro-USB cable and a freely detachable adapter to Type-C. We received a round cable (it is a little stiff) and with an adapter on a leash.
The presence of only one output connector in an external battery with such an impressive capacity can only be explained by the desire of the developers to make the device as compact as possible. You can also look from a purely practical point of view: do you often need to recharge two gadgets at once when you are away from outlets? If yes, and certainly at the same time, and there is no way to wait, then, obviously, this product from Xiaomi is not for you.
Another question arises: why is the Type-C connector used specifically as an input? It is reliable and convenient (because it is symmetrical, that is, it does not need to be oriented in a certain way), but the owner will connect loads to the power bank more often than the external battery itself to the charger. It is also designed for very significant currents by the standards of USB connections, and the speed of charge recovery in the connected gadget is a higher priority compared to charging the battery of a power bank.
Another thing is that the fleet of mobile devices, not only equipped with a connector USB Type-C, but also capable of using most of its capabilities, is still small, but this is only a matter of time, and not the most distant one. Therefore, it would be more logical to assign USB A(f) as an input, and Type-C as an output, and even better, make both connectors Type-C - perhaps then a third one of the same type would fit.
In general, the Mi Power Bank Pro 10000 model turned out to be very compact and elegant, but still a little controversial.
Other organs include an indicator with four white LEDs and a button. If the indicator functions in a completely normal way (with one exception, which is discussed below), then the purpose of the button is somewhat different from what is usual in other models.
So, usually the output (or outputs) of a power bank turns off after a short time when there is no load, and it can only be reactivated by pressing a button. Of course, such a mechanism must have a certain threshold, below which the load is considered absent. But for a number of gadgets like Bluetooth headsets, the normal charge current is very small, and therefore it may well be below this threshold, and you simply won’t be able to charge them.
And in this model there is not only auto-detection of the presence of a load (we connect the device - voltage is supplied to it without pressing a button), but it also provides for working with extremely low output currents: you need to press the button twice, and then the output will not turn off for two hours. True, the Russian-language instructions we downloaded do not say this.
Otherwise, the button works the same as in other external batteries: pressing it once will allow you to check the remaining charge by the number of indicator LEDs that light up at the same time, and in some cases also reset the emergency state after the protection has tripped. If this does not help, then you can try a short-term connection to the charger - we encountered something similar when testing other power banks.
Testing
Charge
The charger was connected to the charger using the supplied cable, during the process the LEDs flashed evenly, their number allows us to judge the charge level.
When connected to a conventional charger with a maximum current of 2.1 A, the consumption was initially 1.0 A, and could increase to 1.1 A in the process; if you turn it on for additional charging when the discharge is incomplete, the current can reach 1.15-1.17 A, but for a short time - then it drops again to 1 A.
The charge in this mode goes long: 8.5-9 hours, and only after about an hour the current begins to decrease. The body of the power bank heats up very little.
When all four LEDs light up, the input current is not equal to zero- it remains at the level of 50-70 mA for a very long time. Of course, we didn’t wait for days for the input current to zero, but after a few hours this didn’t happen. It’s hard to say how this not too large, but noticeable current is consumed, it’s clearly not to power four tiny LEDs; one might assume that this is a maintenance charge, but for lithium-ion batteries this is constant mode not usually practiced.
Using a memory that supports Smart modes Charge, gives a more pleasant picture: the initial current is 1.6 A, it changes a little during the process, but for a long time it is in the range of 1.4-1.6 A; heating is observed, but weak - by 6-8 degrees relative to the room temperature. A noticeable decrease in current began only after 6 hours, and the average charging time was 7 hours 15 minutes. Less than from a regular source, but still a lot.
We tried charging from a source that supports the technology Quick Charge(QC 2.0/3.0). Its output when connected external battery switched to 12-volt mode, the current remained at 1.5-1.6 A for a long time, and after 1 hour 45 minutes it began to decrease - at first little by little, after 2.5 hours (from the start of charging) at a faster pace. The average time was 3 hours 30 minutes, that is, the charge was restored two and a half times faster!
After an hour and a half, the heating reached 11-12 degrees relative to the initial temperature, and did not increase further.
In the last two cases, upon completion, the current was reset to zero.
Discharge
When discharged, the indicators do not light up constantly, like most other external batteries, but flash at long intervals. The number of LEDs that light up indicates the remaining charge - everything is quite normal here.
Measurement data for normal mode are given in the table.
| Current | Output voltage | Time until shutdown | Energy | Efficiency | ||
|---|---|---|---|---|---|---|
| at first | in progress | before shutdown | ||||
| 0.5 A | 5.1 V | unchanged until shutdown | 5.1 V | 14 hours 50 minutes | 37.8 Wh | 98% |
| 1.0 A | 5.0 V | 5.0 V | 7 hours 31 minutes | 37.6 Wh | 98% | |
| 1.5 A | 4 hours 59 minutes | 37.5 Wh | 97% | |||
| 2.1 A | 4.9 V | 4.9 V | 3 hours 30 minutes | 36.1 Wh | 94% | |
| 2.4 A | 3 hours 02 minutes | 35.7 Wh | 93% | |||
| 2.7 A | 2 hours 38 minutes | 34.7 Wh | 90% | |||
| 2.9 A | protection after 7 minutes | |||||
| 3.0 A | 4.9 V | protection after 8 seconds | ||||
In our reviews of power banks, we calculate efficiency as the ratio of the data obtained for the energy supplied to the load to the declared value. We introduced this conditional concept for the convenience of comparing models of external batteries that we have visited with different declared capacities, and usually it is given only for the battery, and so that the comparison is correct both with other models and with Quick Charge modes for Mi Power Bank Pro 10000 ( information about the conversion efficiency for them is not provided in official sources), the last column of the table also used data from a lithium-polymer battery, that is, 38.5 Wh.
The obtained values can be considered excellent result, actually record-breaking, especially because they change little in wide range loads, including those significantly exceeding the declared maximum. In addition, in all measurements the output voltage is very stable and differs little from the standard USB five volts.
The protection is triggered when overloads are close to one and a half times, that is, the overload capacity in the long term is at least 35%, and within a few minutes it can be at the level of 45%.
We also tested Quick Charge modes, which we set using a special trigger. For QC 2.0 you can choose 5, 9 and 12 volts, for QC 3.0 maximum voltage is 12.4 V (remember: in QC 3.0 changes are made in steps of 0.2 V).
Two measurements were made in QC 2.0 with the maximum declared currents for voltages of 9 V and 12 V.
| Current | Output voltage (QC 2.0, 9 and 12 volt modes) | Time until shutdown | Energy | Efficiency | ||
|---|---|---|---|---|---|---|
| at first | in progress | before shutdown | ||||
| 2.0 A | 9.0 V | gradually increases by a small amount | 9.2 V | 1 hour 49 minutes | 33.0 Wh | 86% |
| 1.5 A | 12.2 V | 12.5 V | 1 hour 24 minutes | 25.8 Wh | 67% | |
As you can see, conversion in QC modes occurs with significantly greater losses, and if for the 9-volt mode the efficiency remains relatively high, then for the 12-volt mode it is already at a very average level. That is, for accelerating the charging of a connected gadget, you have to pay for the inefficient use of power bank battery energy.
Naturally, long-term operation under a significant load cannot be done without heating. At first, the part closest to the connectors heats up more, but, thanks to the good thermal conductivity of the aluminum case, the temperature soon becomes almost the same over the entire surface.
The maximum we recorded was when the output was operating in 12-volt mode at a load of 1.5 A: by the time it was turned off, the heating was 19-20 degrees relative to the room temperature, that is, the power bank became very, very warm.
We also tried working with very light loads. Pressing the button once connects the output, but for a short time: about 25 seconds for currents of 20 mA or less; as the load increases to 70-80 mA, the voltage can last for 2.5-3 minutes, but a shutdown will still occur.
If you press the button twice in a row with a minimum interval, the output is connected even in the absence of load. A sign of transition to this mode is alternate short-term blinking of the LEDs. We did not check whether this regime would last the promised two hours - we only had enough patience for 30 minutes. You can switch off early by pressing the button once.
Mi Power Bank 5000
Information also had to be obtained from the global website, since this model was not available in the Russian-language section of the manufacturer’s website at the time of writing the review. The model index NDY-02-AM indicated there coincided with that shown on the case and packaging.

| Description on the manufacturer's website |
Both models are very similar both in appearance and design. Only aluminium case Mi Power Bank 5000 is lighter - not gray, but rather silver, and the plastic on the end caps is milky white. There are no beautiful chamfers on the edges, but it looks like the aluminum layer itself is a little thicker - we cannot say this definitely without accurate measurements, and we were not allowed to open this model either.
At one end there is the same set of organs: two connectors, four indicators white and one button. Only this time the input is not Type-C, but Micro-USB, like the vast majority of similar products.
Both models are similar in size, the thickness of the Mi Power Bank 5000 is 20% smaller - it seems significant, but in reality these almost three millimeters of difference are noticeable mainly in direct comparison. But the youngest is almost a third lighter in weight, and you can feel it even with your hand, without any measurements.
The design of the packaging is even simpler: if the Mi Power Bank Pro 10000 had at least an image of the power bank, then for this model the front side of the box contains only the company logo (the authentication sticker is on the other side). But the inscriptions both on the packaging and on the “blind” end of the case were in English, and we received the manual in Russian.
Once again, only the cable is included - this time flat, with USB connectors A(m) and Micro-USB. Length 17 cm, no adapters.
The presence of protection against overload and excess voltage, short circuit, overcharge and deep discharge is declared. The descriptions talk about auto-detection of the presence of a load, that is, the button is also used not to connect an output, but only to check the charge level, but this time there are no instructions about working with extremely small loads - you will have to check in practice how things are.
The model also uses a positive temperature coefficient battery, so temperature Range exploitation is just as wide.
The “reduced to five volts” capacity in milliamp-hours is not indicated in this case, but it can be easily calculated by yourself using the algorithm we presented above. Although the specification does not contain a line for conversion efficiency, a value of 93% is found in the descriptions.
Testing
Charge
We tried charging the power bank not only from different chargers, but also using different cables, fortunately, you don’t have to look for them for a long time.
We started with the complete one, connecting it to a charger with support for Smart Charge (PowerIQ) and a maximum output current significantly exceeding 2 A (in reality, and not just according to the indicated parameters). The initial charge current was a pleasant surprise: 1.7-1.75 A, and soon even increased to 1.85-1.9 A, and began to decrease after two and a quarter hours. The total time was 3 hours 15 minutes, that is, it fully corresponds to the declared value. At the same time, the case warmed up a little, by 9-10 degrees relative to the initial state.
But the point is not at all in Smart Charge, but in the cable: if you connect a standard cable to the most ordinary adapter with an “honest” maximum of 2.1 A, then the situation changes little: the current starts at 1.7 A and for a long time remains at the level of 1.6-1.75 A, a decrease is observed after two and a half hours, and the total time is 3 hours 45 minutes.
If the cable is replaced with another one, and not quite a “left one”, even with a designated cross-section of 28AWG (0.081 mm²), and not an exorbitant length - 95 cm, then the current under the same conditions will not exceed 0.8-0.85 A , starting to decline in the last 50-55 minutes. The total charging time was 5 hours 40 minutes.
With a third cable, a meter long and without any “identification marks”, from a conventional 2.1 A charger the current did not exceed 0.45-0.5 A, and therefore charge restoration took 9 hours 45 minutes, the current and In this case, it began to decline in the last hour.
Of course, the values indicated for the charging time are approximate, because the preliminary discharge was carried out with different currents to fill out the table below, and low currents discharge the battery more strongly. However, this may explain the difference of tens of minutes, but not several hours.
There are no miracles here. We measured the voltage drop on these cables: for the first (standard) at a current of 1.0 A it was slightly more than 0.1 V, for the second it was 0.45 V, which agrees well with the normalized resistance for 28AWG of 0.213 Ohm/m (v the cable has a pair of wires almost a meter long), and we can assume that the cross-section of the wires of the standard cable is the same, it’s just about five times shorter. On the third, almost 0.8 V dropped - the same amount less compared to the nominal five volts would have been supplied to the input of the power bank at this current; It’s surprising that with such a cable the device was charged at all.
The built-in indicator is quite accurate: as soon as the last LED lights up continuously, the current becomes zero.
Discharge
The behavior of the indicators is the same as that of the Mi Power Bank Pro 10000: not constantly lit, but briefly blinking.
Voltage at no load or at low output currents 5.1 V.
The measurement data is given in the table.
| Current | Output voltage | Time until shutdown | Energy | Efficiency | ||
|---|---|---|---|---|---|---|
| at first | in progress | before shutdown | ||||
| 0.5 A | 5.0 V | stable, but 20 minutes before shutdown it drops abruptly by 0.5 V | 4.5 V | 7 hours 04 minutes | 17.5 Wh | 95% |
| 1.0 A | 5.0 V | unchanged until shutdown | 5.0 V | 3 hours 23 minutes | 17.0 Wh | 92% |
| 1.5 A | 2 hours 07 minutes | 15.9 Wh | 86% | |||
| 2.1 A | 4.9 V | 4.9 V | 1 hour 27 minutes | 14.9 Wh | 80% | |
| 2.4 A | 1 hour 12 minutes | 14.2 Wh | 77% | |||
| 2.5 A | the output is not connected, protection is triggered | |||||
When calculating the efficiency, we took the value declared for the energy of the built-in battery to be 18.5 Wh. The results were quite good, especially at currents up to 1 A, but overall not as outstanding as the previous model. However, here too it should be noted the high stability of the output voltage, despite the annoying drop at the end of the discharge with a current of 0.5 A: if you count, it lasted less than 5% of the total time.
The overload capacity is also quite good: the power bank confidently operates with an overload of up to 15% without deteriorating the output parameters. True, the output at currents above the stated maximum may not always be automatically connected; sometimes you have to “spur” the device with a button. Starting from 2.5 amperes, it is not possible to make the device work at all.
At low and medium currents, the heating of the case is insignificant; at 2.1 A in an hour and a half it heated up by 13-14 degrees compared to initial state, then the temperature remained virtually unchanged. The same heating occurred just before the shutdown at a current of 2.4 A.
The function of long-term connection of an output by double pressing a button is not implemented in this model, but otherwise a power bank with light loads behaves in the same way as the product described first: a single press will turn on the output voltage, but only for a while. The only thing that differs is the proportion between the load size and the time before turning off after pressing the button: at very low currents it takes 20 seconds, at 60-70 mA just over a minute, at 80-90 mA it already works for a very long time (waited 10 minutes, does not turn off).
Quick Charge support is not stated in the description, but we still spent a couple of minutes checking: the trigger we used could not enable either QC 2.0 or QC 3.0.
Bottom line
We reviewed two samples of “nutritional” products Xiaomi, briefly the impressions are as follows.
Mi Power Bank Pro 10000— the model is very stylish, compact and with excellent parameters (the results of our tests were sometimes even better than promised in the specifications), but a little contradictory. One of the contradictions, as often happens, is related to the advantages: the battery capacity is very large for such dimensions, and the maximum load current is also more than decent, but there is only one output connector - you cannot connect two gadgets at the same time. The purpose of the output connectors is also puzzling: it would be more logical to make Type-C the output connector and USB A(f) the input connector.
Mi Power Bank 5000 smaller, simpler, but also cheaper. Although this is not outstanding in terms of properties, it is quite a good product that corresponds to the declared parameters.
It must be said that the list of power banks produced by the company is not limited to these two models, and will certainly be expanded in the future. We can hope that the rest of the brand’s external batteries are at least as good as the youngest of those reviewed.
Now we have a century portable devices, various devices, smartphones, tablets, etc. It is not surprising that the problem of charging them is especially acute, because despite the fact that some devices come with powerful batteries, their charge is sometimes not enough for long-term continuous operation. Now this problem at least partially solved, thanks to the Xiaomi Mi Power Bank 10000mah - a portable external battery that can restore the functionality of the gadget almost immediately after connection. But for the smartphone to be fully charged, you need to wait several hours.
So now you don’t have to urgently look for where to recharge your gadget when it runs out of charge at the most inopportune moment, for example, when you are in the city center and, as luck would have it, there is not a single free outlet around. Having bought this device, you can forget that such a problem once existed at all. She will be forgotten like a bad dream. In addition, among power banks, Xiaomi products stand out not only for their quality and power charge, but also for their at an affordable price. Price of this device almost two times cheaper than analog devices, but produced by another brand.
Common parameters
An additional supply of energy will definitely not hinder any active user. But before buying any device, you need to familiarize yourself with its characteristics. On the manufacturer's website we found the following information regarding the configuration of devices of the type in question:
- Model NDY-02-AN;
- Lithium-ion rechargeable battery, which turns it into a reusable device, careful handling of which will allow the battery to operate for several years;
- The input voltage is 5.0V, and the output voltage is a little more - 5.1V;
- The input and output current has the following parameters: 2000mA* for input, and 2100mA* for output;
- Nominal capacity Power Bank Xiaomi is 3.6V/10000mAh*;
- The time it takes to charge the device is 5.5 hours. At the same time, the package includes charging cable for the battery itself and for the gadget 5V/2A, and with a comprehensive 5V/1A cable, charging can last 10 hours;
- Automatic detection of gadget connection and disconnection;
- There is a built-in mode that allows you to automatically turn on protection against such frequent phenomena in our network as changes in input or output voltage. In addition, equipment can protect itself in case of excess current, short circuits, overcharging, overdischarging and other frequent phenomena;
- You also need to take into account the operating temperature, which when charging is 0℃-45 ℃, and when discharging -10℃-50℃;
- The power bank package includes the following elements: the Power Bank itself, instructions for it and USB cable for charging;
- The dimensions of the device are 91 * 60.4 * 22 mm, and its weight is 207 g.
In general, as you can see, in terms of parameters, a power bank is a pretty good alternative to an outlet, especially since it can be used even in nature, when the nearest electrical wire is several kilometers away.
Appearance of Xiaomi Mi Power bank 10000 mah
The appearance of the power bank even turned out to be somewhat noble. This device looks really wonderful and recognizable. Carrying the device in your purse is convenient. It is very compact and stylishly designed, so it won’t get in the way even in your pocket. The body is made of quality materials. In particular, anodized aluminum is used, which is diluted at the top and bottom with light plastic inserts. Despite the fact that plastic is used, it is also of high quality, so no squeaks are heard, and the structure is connected correctly everywhere.
As for the dimensions, the dimensions indicated in the instructions coincide with those that actually exist. But let's take a closer look at the features of the device in question:
- The manufacturer's logo is painted on the front side of the battery;
- On the back side is the address of the mi.com website, where you can go and see more detailed review the device in your hands;
- On the top edge of the power bank 2 10000 there is a button that can turn the device on or off. In addition, there is a micro-USB connector. It is designed to charge the Power Bank itself. But the USB connector is used to charge other devices (smartphone, tablet, etc.). Also on this panel there are four LEDs, the task of which is to display the state of charge. It works according to the following principle: if one LED blinks, then the charge level is only 0-25%, one light is on constantly, and one blinks, then the charge level is 25-50%, and so on according to the same principle. If all four lights are on continuously, then the 10,000 mAh charge is complete;
- The main parameters of the device model are indicated on the bottom edge. In particular, the serial model number, capacity at 3.6V/5.1V, charge/discharge voltage/current, minimum/average capacity/power value are written here.
In other words, you just need to pick up the Xiaomi Power Bank 10000 device to know exactly what its characteristics are. You don't even need to read the instructions.
And if you don’t like something in the design, there is another portable one Charger Xiaomi, which is called Xiaomi Mi Power Bank Pro 10000 mAh. Its peculiarity is that it has a dark gray color, while the device in question is light.
Using the Power Button
The power button, as already mentioned, is located on the top of the device. But what is it for, and how to use it? Let's try to deal with this issue right away, so as not to break the Xiaomi Power Bank 10000 we just bought.
If you press the power button once, the result will be:
- The device's battery level appears. How exactly - we have already told - using indicators;
- Voltage will begin to be supplied if at this moment the Power Bank is not in working condition;
- The button turns on and off the devices connected to it Xiaomi gadgets, and it can be not only a smartphone, but a flashlight, etc.
And here double tap pressing the button in question will allow you to switch to charging mode for a smartphone or tablet with low current consumption. During this process, the battery will not go into standby mode for two hours. This mode is suitable for charging devices that do not require high voltage. For example, you can take the Mi Band tracker or other similar devices.
In general, the operating modes are quite convenient if you know in which cases they can be used, and in which it is better for the Xiaomi Mi Power Bank for 10,000 mah to work at full capacity.
How to distinguish an original from a fake
Despite the fact that Mi Power Bank 10000 mah is sold almost at cost, they also manage to counterfeit it and sell it even cheaper. In our stores, such a device will cost about a thousand rubles. The price is purely symbolic, since an external battery with the same capacity, but from a different manufacturer, will cost at least several times more. So where can we reduce the price?
As it turned out, there were craftsmen who replaced the filling of the block with outright garbage, which would not be enough even for one-time use. Not surprising, because reliable batteries were replaced with cheaper and less powerful ones. The wiring that ensures the transmission of contact was generally used there, the thinnest, but cheapest. Even the case was made as cheap as possible. It is clear that it is dangerous to even pick up such a device, and when connected to the network it can explode or best case scenario just burn out.
In order not to acquire such a low-quality gadget, you need to know how to distinguish a fake from an original:
- The first sign that you have an original is the high-quality packaging made of white cardboard. In addition, it should have a sticker with license code, consisting of 20 characters. To check the code, you need to go to the official Xiaomi website and enter the received characters. If everything is good, then you have it in your hands original box. But let's look further.
- The second option is to look at the charging cable that was in the package. If you have original cable, then inside the plug there is USB plastic with a black connector. But the fake devices are white.
- Inscriptions on Xiaomi 10000mah. IN original device The inscriptions are clear, but applied in light gray paint. But fakes are signed with black paints, the edges of which are blurred with various smudges, etc. In addition, mistakes are made there. For example, we came across an option where “LHON” is written on the battery, instead of correct option"LI-ION".
- There is a logo on the front of the device. In the original it is signed with slightly darker paint, while the fake has a slightly larger inscription than the original. And if you look closely at the panel itself, you will notice that there is no shine in the original, or rather, it is there, but the body is almost matte, noble. But the fakes have such a shiny panel that it feels like they were coated with glitter varnish. And if you look closely, fake batteries have scuffs, so this is a reason to make sure that this is a fake.
- The indicators are covered with protective transparent plastic, which has a small diameter. As for fakes, the indicators are not only larger and less accurate, but at the same time there is no protection on them. There is an “MI” logo at the end of the USB port.
- Xiaomi 10000 mAh batteries were manufactured by LG. They are directly connected to printed circuit board. But fake batteries have filling from an unknown manufacturer, and the batteries are connected to the board with thin wires that constantly overheat.
In general, it is quite possible to identify a craft by external signs; you just need to be a little more careful.

Good day, dear readers of this review.
IN given time, at the peak of the proliferation of smartphones and tablets, the problem of charging these devices is quite acute. Many devices with active use discharged during the working day, or, for example, when traveling it is simply not always possible to charge the device from an outlet. It is in such cases that such a thing as a Power bank comes to our aid. It will help “breathe” life into your dead device.
Among powerbanks, Xiaomi models, enjoy well-deserved respect, primarily for their quality and affordable price. The reviewed charger, with a capacity of 10,000 mAh, in my opinion, is “popular” (as well as previous model at 10400 mAh), combining low
price, small size and sufficient capacity.

Packaging and equipment
We are greeted by a small box made of white cardboard. I won’t pay particular attention to the packaging, so I’ll just givephoto from the front side, on which the manufacturer’s company logo flaunts. On the left and right sides, there is a code to check the originality and brief characteristics respectively.
The delivery set includes a power bank, a charging cable (for the device itself or the equipment connected to it), and instructions.
Appearance
The body is made of aluminum with plastic inserts on top and bottom. According to my measurements, the dimensions coincide with the declared ones (90*60*21.5 mm).- On the front side there is the manufacturer's logo.
On the back is the website address mi.com.
On the top edge there is an on/off button, a micro-USB connector for charging the powerbank itself, a USB connector for charging other devices and four LEDs indicating the degree of charge (one LED blinks - charge 0-25%, one lights up constantly + one blinks - 25- 50%, two lights + one blinks – 50-75, three
shine + one blinks – 75-100%). If all LEDs are lit continuously, the battery is 100% charged.
On the bottom are the main characteristics (serial model number, capacity at 3.6V/5.1V, charge/discharge voltage/current, minimum/average capacity/power value).
It fits comfortably in the hand, although it does slip a little.
A few words about copies
To check the originality of the product, you can use the website by entering the 20-digit code located under the scratch field on the box; Also pay attention to the USB connector, there should be an inscription “mi” inside it. Also pay attention to the color and font of the text (in the photo of the bottom edge of the charger), the originals use a faded font.Test
Before moving on to the tests, I will make some clarifications.- The capacity indicated by the manufacturer on the powerbank is the capacity (or the sum of capacities) of the built-in battery(s).
- In chargers of this type, conversion losses must be taken into account. From the 3.6-3.7V internal battery, it is converted into a 5V output voltage (the efficiency of this conversion is indicated on the device).
To discharge the Xiaomi 10000mAh, we will use a Xiaomi MiPad with a 6700mAh battery.
As you can see from the photo, the final “drained” capacity is 6276 mAh (the tablet is 91% charged). Which, judging by other reviews, is typical.
The formula for calculating the actual capacity looks like this:
Actual Capacity = (Declared Capacity * 3.6V) / 5V * Efficiency
3.6V is the battery voltage (indicated on the official website, or on the powerbank itself).
Based on the fact that we know the actual capacity (given from the USB connector), we can calculate the declared one.
Declared Capacity = (Actual Capacity * 5V) / 3.6V / Efficiency
Efficiency declared by the manufacturer is >88%, let’s take it for calculation minimum value in 88%.
(6276*5)/ 3.6/0.88=9905 mAh, which is very close to the declared value (another confirmation that the manufacturer did not deceive).
A small comparison with Xiaomi 10400 mAh.
Compared to the 10400 mAh model, the dimensions have decreased (91 * 60.4 * 22 versus 90.5 * 77 * 21.5 mm), progress is obvious. Achieved by replacing four built-in batteries with a capacity of 2600 mAh, with three 3350 mAh batteries. The difference in theoretical capacity between devices is 400mAh. In my case, the difference was 483 mAh (probably due to the fact that the more capacious model has a declared efficiency of >90%).
The edges of the body have been chamfered. For the 10400mAh model, sharp edges could cause mechanical damage, when carried along with anything else (in a bag, backpack).
Case
Also sold for power bank Silicone Case. This is what the powerbank looks like in it.
The reasons why you can use a case are a more secure grip in your hand, and protection of things carried with the powerbank (for example, when carrying it in a bag/pocket and simultaneously charging a smartphone or tablet).
