Portable charging power bank. Portable charger (power bank). Criterias of choice

Your smartphone is dead and there is no power outlet nearby? The situation is common - modern smartphones quickly dry up if you use them to their fullest. This is where a portable charger comes in! But how to make the right choice so as not to be left without communication and entertainment? Let me show you what I chose and what problems I encountered in the end.

According to tradition, first a little theory.

Nowadays the most popular power source is a lithium battery. They are everywhere - in phones, cameras, laptops... Even disposable electronic cigarettes have a rechargeable lithium battery.

The most common format for lithium is 18650 (18*650 mm). Such “banks” are used in most laptop batteries.
Well, since laptops are one of the most popular products in the world, manufacturers are striving to improve this particular type of battery.
Which makes 18650 ideal for use in flashlights, e-cigarettes and portable chargers.


Lithium batteries have their drawbacks - they do not like to be very discharged and deteriorate when charged uncontrolled. Therefore, in regular stores you will not find “naked” lithium batteries; they are built into devices or sold together with a charge/discharge controller. But no one is stopping you from finding a used laptop battery and removing the batteries from it. Their condition may be far from ideal, but they are a freebie.


It would seem, what does this have to do with laptop batteries, if portable chargers are sold ready-made and often non-separable? It’s enough to type the cherished words in the search - and here they are, full of bright colors:


Let's think about it. The average buyer, of course, will never disassemble the charger and never think about replacing the batteries. Therefore, the manufacturer can put anything in there - from low-quality Chinese batteries to the same used laptops. But even if the power bank contains high-quality batteries, they do not last forever - a couple of years and they’re in the trash. Therefore, the ability to replace the power source is simply necessary, otherwise the device may turn out to be “disposable”. Try to find a replacement battery like this:


I’m used to buying everything from China, and I recommend it to you too - you won’t find normal things here at a reasonable price. More than two years have passed since my review, during which time I ordered dozens of Chinese goods and visited many sites. There have been cases of fraud, and there have been very long delivery times. I liked it most for the very fast delivery and many free shipping options. There I bought several chargers I liked.

All of them can be replaced with a battery and, importantly, are supplied “empty”, that is, batteries are purchased separately.


Familiar to all flashlight lovers, the ML-102 is very easy to use. Just insert the battery and... that's it. There are no buttons or charge level indicators. I connected the phone via USB - the charge started, connected via microUSB to the PC - the battery itself began charging. Stated current limit - 1.2A

The blue LED shows the current current consumption via USB. The brighter, the more power-hungry device is connected.


Red changes to green when battery is fully charged


The internals are as simple as the charger itself:



We connect the consumer to 1A and see that charging works fine:

When the battery is discharged, the charger tries to supply the requested current until the last minute, then goes out:


My conclusion: the best charging is 1*18650. It is extremely simple and therefore convenient. Due to the independence of the charging and conversion circuits, you can simultaneously charge it and connect something to it. But if you have a completely discharged smartphone, you won’t be able to “squeeze the last juice” out of the charger - it won’t be able to deliver the required current and will pass out.

The downside is that it is not designed for protected batteries. They simply don’t fit in there, although some manage to push them into it by modifying the design with a knife and a file. There is no charge level indicator. It is constantly on and in standby mode (the blue diode is barely noticeable, but lights up).


This charger is larger; it can fit three batteries. Some versions also have a built-in flashlight (it shines really well). There is a button and a charge indicator. When in use, the indicator alternately flashes red/green/yellow; when charging the internal batteries, it flashes first red, then orange, then green, depending on the charge level. The declared current is 1A


Everything inside is not very good - the LED has no cooling, some parts are not soldered. The photo shows details from versions with and without a flashlight:



At the moment, I don’t have such a charger on hand, so you won’t see the tests.

From the conclusion - I didn't really like it. Although this device has three batteries, all three channels are independent! This is good in terms of the fact that the batteries will not influence each other, but the bad thing is that energy is taken from only one of them at a time. If none is able to supply the requested current, the device turns off. Batteries connected in parallel could “jointly” produce the required current.

What I like is that it’s convenient to change batteries. I took the cover off, changed the battery and I was done. It is made really conveniently, there are special recesses for removal. There is a lot of space, protected batteries can also be placed, the springs are soft and inserted without difficulty.

Also, when used, the indicator simply blinks. It is impossible to find out the charge level without disconnecting the device being charged. Power supply stops immediately after disconnecting the cable, there is no delay. And there is no way to turn off charging during operation.


Also for three batteries, but not triangular, but flat. Instead of a three-color indicator, there are four blue LEDs. But there are already two USB ports, 1A and 2.1A. When in use, the current charge level is displayed every 5 seconds. When charging, the charge level is also visible.


Everything is held on by screws and is inconvenient to disassemble. And it’s also difficult to assemble, the springs try to push the plug out:




It also copes with 1A consumption (it also supports 2.1 A, but I haven’t found anything that consumes that much):


And it turns off in the same way if you connect a power-hungry device when the charge level is low:


and then immediately disconnects


The result is a good charger for 3*18650, maybe one of the best. Full metal body. The button is recessed so that it is not pressed accidentally. All batteries are placed in parallel, thereby increasing operating efficiency. It can produce more current, therefore, it has two USB ports, one of which is 2.1 A. The indicators work both when in use and when charging from the mains.

Of the minuses, it also cannot be turned off with a button, the button is only for turning it on. It turns off itself after 10 seconds of inactivity. I have already mentioned the impossibility of quickly changing batteries and not very convenient assembly with screws.



Also for 1 battery, like ML-102. Has a button, 5 indicators, supports a “special” mode for iPhone. Includes adapters for various phones and a flashlight. There are no specifications for the current output.


Alas, I couldn’t take it apart, so we won’t see the insides. The plastic is filled very tightly.

Under the same conditions, charging was only able to produce 0.66A in normal mode and 0.87 in special mode (for the iPhone):


The special mode turns on only for a couple of minutes, so don’t be fooled by high values


Interestingly, it can also work with a very discharged battery (possibly causing a drop in voltage):


This is observed only in a “special” mode, but for emergency cases it will do!

To sum it up: it was assembled conscientiously, it has been working for two years. The standard cable was of poor quality, so I soldered a new one. Charging is leisurely, but more efficient - it will work until the end, limiting the output current. The only one we review that can be turned off with a button during operation!

The downside is that there is only one USB connector. Charging from the network occurs through it. So without a special cable (USB - USB), you won’t be able to charge it yourself.

What conclusion can be drawn from the options considered? There are no universal things. To each his own. It’s more convenient for me to throw a 1*18650 power bank and several batteries into my backpack. Some people find Ruinovo more convenient - tighten it with screws and forget about it until you have to change the batteries. In general, I told you all the possible problems when choosing a portable charger - don’t be mistaken.

But I missed one point. Batteries! Shouldn't we take them out of laptops? You need high-quality ones so that such a charge will last for a long time. And the Chinese are trying to slip in a cheap one under the guise of a normal battery:


First of all, remember - there are no 18650 batteries with a capacity greater than 3400 mAh. And even those are achieved only in non-standard operating modes (which are not available in standard power banks). Standard capacity 2200 mAh, higher quality ones - 2600 mAh

Also, you shouldn’t take Chinese brands (UltraFire, TrustFire, FandyFire... ***Fire) - you won’t understand where the original is and where the fake is, you can run into batteries with a capacity of 1000 mAh and even 250 mAh instead of the indicated 2600. (see photo above )

If you still want to save money, pay attention to the captions about the actual battery capacity on the website:


If the actual capacity is less than 2200 mAh, it’s better not to take it. It's not worth it.

Interested in other things? Write in the comments! Perhaps I will choose your topic for review next time.

Hi all. Today we’ll talk about a fairly well-known device. The twenty-first century is the century of information technology. Portable devices that constantly lack power. Especially smartphones based on the Android operating system are very power hungry. The browser alone uses about 80% of the smartphone's battery capacity. And, as you know, the Internet is used very often now. It’s even better to say - constantly! Check the weather, the dollar exchange rate, respond to messages on social networks, check your kidney, order pizza for work, order a taxi, book a hotel room - this is not a complete list of the purpose of a smartphone as an intermediary between the user and the Internet. In such cases, you can’t go far from the outlet. And if there is no access to an outlet...

In general, where there is a problem, a solution to the problem is born, and in this case it was proposed to assemble a portable charger, also known as an external battery, also known as a power bank.

A kind of portable charger for replenishing the battery of your smartphone.

What is Power Bank?

Translated into Russian, Power Bank is an energy bank. That is, an array of batteries assembled in one housing. There are several spellings of this word: Powerbank and Power Bank, as well as external battery for smartphone/tablet, mobile battery And autonomous charger.

Power Bank 2600 - universal charger

Hello, my dear readers! Today I will talk about the portable charger Power Bank 2600. A mobile phone for me is a universal and irreplaceable thing. During the day, with its help, I listen to music, read books, go online, watch videos, and do much more.

Unfortunately, this quickly drains the battery power, so very often my phone turns off at the most inopportune moment when I need to make an important call. One friend, knowing about my problem, decided to help me out and gave me a Power Bank charger. Previously, I did not even suspect the existence of such a device, but, by the way, it is very useful and convenient. Now I’ll tell you more about it.

My review of the universal charger Power Bank 2600

What is Power Bank

This device, despite its small size, is equipped with a fairly powerful built-in battery, which makes it a reliable external source of energy for many electronic devices actively used in everyday life.

The device was packaged in a small cardboard case with a transparent plastic window. Along with the device, the kit included additional adapters and instructions.

The charger looks like a small keychain; it even has a special ring on it. This keychain can easily fit in a small handbag or even a pocket. What distinguishes the Power Bank from a regular key fob is the presence of two ports – USB and micro USB. The device is also equipped with an LED indicator that shows the battery charge level.

Its shape is rectangular, the body is made of high-quality plastic. Power Bank comes in several colors, you can choose neutral white and black, or more cheerful yellow, pink, blue and green.

Device dimensions:

  • Length – 10.6 cm;
  • Width – 2.6 cm;
  • Height – 2.6 cm.

Weight – 72.5 g.

Specifications:

  • Battery: polymer lithium, capacity – 2600 mAh;
  • Input: voltage – 5 V, current – ​​1000 mA;
  • Output: voltage – DC 5 V, current – ​​1500 mA.


What devices is Power Bank suitable for?

Due to the fact that the vast majority of modern electronic devices are equipped with standard USB ports, Power Bank is a universal device. Thus, you can use it to charge:

  • mobile phone;
  • digital camera;
  • video camera;
  • tablet;
  • player;
  • GPS navigator;
  • game console;
  • many other devices.

In order to ensure complete safety of expensive electronic devices when charging using a Power Bank, this device is equipped with six protection functions:

  • from short circuit;
  • from energy overload;
  • from increased charge;
  • from overvoltage;
  • from overcharging;
  • from overheating.

The high quality of the charger's electrical circuit prevents energy loss and ensures its energy efficiency at 90%. Thus, the Power Bank battery is enough to fully charge the smartphone battery several times. Obviously, having such a device allows you to forget about situations when your mobile phone runs out of charge and turns off in the middle of the day.


How to use the device

Before you start using the Power Bank, you need to charge its battery. To do this, using the included adapter, you need to connect the device to a personal computer, with the help of which charging will take place. So I did. After connecting to the computer, the LED indicator on the device lit up, which meant that the battery had started charging. When it was fully charged, the indicator went off. The whole process lasted a little over two hours.

After this, the Power Bank can be used to recharge a smartphone or other electronic devices. To do this, you just need to connect a portable charger to them using a cable with a USB connector and wait for the device to be fully charged; this may take from one to several hours depending on the battery capacity.

A power bank can also act as a flashlight. To turn on the light, you need to press and hold the power button.

I am very glad that thanks to a friend I got this wonderful charger. I attached it to my keys and always carry it with me just in case, and it has helped me out more than once. Now I can listen to music and watch movies on my smartphone as much as I want without fear that it will run out and I will be left without connection. The device also saves me if I forget to charge my phone at home. It is very comfortable!

And the Power Bank is simply irreplaceable on various trips or on country holidays. With it I can charge my phone, camera or tablet at any time, so I don’t have to worry about getting bored without music or not being able to take a photo as a keepsake.

A test order of power banks, batteries and lamps has arrived from Taobao.com
Our impressions, review and feedback from the products received.

Power banks - external mobile batteries for charging phones and tablets

At the end of 2015, Crimea began to experience a significant shortage of electricity, and therefore we remembered such irreplaceable assistants of a modern person - Power Banks. Essentially, this is an external battery (portable charger) from which you can charge your mobile phone, tablet, mp3 players, GPS or any other mobile products that can be charged from a computer or charged via a USB cable at any time. How convenient and useful these things are, especially for people who constantly talk on the phone, we wrote here: Having made a test order, we’ll tell you what we received.

When preparing the first joint venture, we chose from many proposals the most practical, reliable and inexpensive models for every day. The product itself is not difficult to manufacture, it’s just plastic, a board and a couple of plates with springs, so almost every handicraft industry that assembles electronics produces its own types of power banks. Manufacturers try to distinguish themselves only in design, because... The functions of power banks are almost the same. The difference between inexpensive models is only in the quality of execution, the number of batteries (from 1 to 10) and the number of output connectors (1 or 2).

So, from the first joint venture we brought:
— Round, the cheapest power bank, for 1 18650 battery. Price: 100 rubles.
— Rectangular high-quality power bank from PUDI Energy for 4 18650 batteries. Price: 375 rubles.
— Rectangular homemade power bank for 8 18650 batteries. Price: 395 rub.
—
— Xiaomi lamps, not original of course. Price: 80 rub.

Portable phone charger

Simply an irreplaceable thing for active people who cannot part with their mobile phone. Small, compact, easy-to-use portable charger. You can always connect your mobile phone to it and talk, talk, talk... or play. Despite the ridiculous cost, it works reliably and really helps if the phone is discharged. A useful thing, for example, for schoolchildren, who can play games and lose their phone while they are at school, and when they need to call home, it turns out that the battery is dead. Convenient for everyone who constantly walks around with some kind of bag, purse or briefcase, because... Doesn't take up much space.

The device can accommodate 1 18650 battery. There is a USB output and a microUSB input. The portable charger can charge and charge itself through one cord, which is plugged in one way or the other. Near the connectors there is a hole with an LED that shows the current state of affairs. Is energy being released, is the battery charging and is it charged? It makes sense to install powerful batteries on such small power banks, because... They only have one battery. For example, branded SANYO at 3400mA, or Panasonic. The lid opens quite freely; if necessary, the battery can be recharged with a separate charger that supports. Otherwise, you can charge with a regular phone charger. Plastic colors may vary; we got black ones. A must-have device (like the Xiaomi lamp, but more on that below).

Portable battery for 4 batteries with digital display.

A high-quality and quite stylish portable battery from PUDI Energy. Normal plastic, looks very good, expensive. Unlike simple plastic boxes (more about them below), it has its own design. The sides are slightly concave, the buttons are beautiful, the back plastic cover is embossed like the front metallized one. On the back are the parameters and even the RoHS logo (a directive limiting the content of harmful substances in materials). Convenient for use not on the run, but in stationary conditions (at home, at the institute, at work), i.e. where you can charge the power bank and phone separately. Or keep it in your bag and charge it while talking on the phone through a long wire, because... The weight of the product with batteries is slightly more than 300g. The power bank has a second high-power output, which allows you to recharge tablets. At a price several times less xiaomi external battery, works no worse.


The portable battery fits 4 batteries, which with their average power (2600mA) gives a total of 10400mA. Provided that in reality it will give 5-7 thousand, and not 10 (losses + the Chinese lied about the battery capacity), a modern smartphone can be fully charged a couple of times. And if you put good 3000mA batteries there, you can safely charge tablets. Very convenient screen shows the remaining capacity as a percentage, as well as the charge level when charging. The blue backlight turns on when a wire is connected or when a button is pressed. There is a protective film on the screen. There is even a mini flashlight made of one LED. If the light switches off takes you by surprise, just press the power button twice and the flashlight will light up. The power bank has 2 USB outputs, 1 and 2.1 amperes. The first is for phones, the second is for tablets. In general, the product is worthy. It costs 50-70 rubles more than its industrial counterparts. Available for 4 and 6 batteries with a screen and for 6 and 10 batteries without a screen.


External battery with screen for 8 18650 batteries.

This is undoubtedly a powerful device for charging phones and tablets. The design is certainly simple, but it will serve perfectly as a home energy bank. Suitable for a family or team when someone is constantly charging something. Or for those whose lights are turned off for the whole day.
Initially, when choosing a cheap model of a powerful external battery, we weeded out many similar devices apparently made in the basements of the Uncle Cho and the Illegals factory. The main difference between cheap external batteries is mainly the quality of plastic. This is the most decent option of all that we evaluated based on Chinese reviews. In the end, it turned out that the plastic is strong and reliable. The lid with numerous latches, closed once, closes for centuries. After installing the batteries inside, it is better not to go in there. The body is corrugated into small pimples.

There are two outputs, 1 and 2.1A. The flashlight is made with two LEDs. The screen is the same as on the previous model from PUDI. When setting 8 to 2600mA, the resulting capacity is 20800mA, which is very decent. This power bank is perfectly characterized by the phrase: Cheap and cheerful!

Xiaomi LED lamps on a flexible leg

Of course not original. The lamp leg is flexible and can be bent at the desired angle. It is inserted into a USB connector and does not have a switch. In combination with any of the power banks, it is a very useful and necessary thing. The LEDs shine brightly; when the lights are off, you can see what is happening in the room. Very convenient to read. Plugging one battery into a round power bank and walking around the room, you feel as if you are walking with a candlestick. After incandescent lamps, the light from this lamp seemed a little greenish to me. The price of the lamp is ridiculous: 80 rubles.

Examples of using.

Smartphone technology has come a long way over the past few years, but there is a problem - battery life. Of course, batteries are getting bigger and manufacturers are becoming more inventive, although many of us still have the problem of never having enough charge.

A selection of the best portable chargers

A power bank is a device used to charge gadgets when there is no power supply. Their connection occurs via a wire connected through the built-in USB port. However, in order to give charge to other devices, the Power Bank itself must first be charged.

Basic ways to charge Power Bank

When planning to purchase this device, you should ask how to charge this particular model and how to use it correctly. Despite the ease of operation, any model may have some differences and nuances. In order for the device to last a long time, you need to learn how to properly charge the Power Bank portable charger by looking at the instructions.

From a 220V outlet

The main question that interests buyers is whether it is possible to charge a power bank using electricity, because this charging method is the most convenient and familiar. To do this, you will need to purchase a network adapter - you need to buy it separately; it is not included in the Power Bank package.

Since the external battery is designed for smartphones, it is logical to use a telephone charger for charging from the network. Given that the standard charging time for an external battery with a capacity of 4000 mah - 5000 mah is 4-5 hours, it is most convenient to plug it into the network at night. Charging from the network is much faster than via a USB port.

From computer via USB

The simplest option that makes it convenient for every user to charge a Power Bank is a computer. To do this, you just need to connect it to a working device using a cable via a USB connector. Charging occurs during its operation unnoticed by the owner.

From the energy of the sun

Many users are interested in whether it is possible to charge a power bank in the sun. This is the most economical and inexpensive way - you just need to place the device in the sun. However, it is only suitable for those external batteries that have a solar panel.

From car cigarette lighter and other devices

Users are interested in the question of whether it is possible to charge from an outlet in the car. Car enthusiasts who have a cigarette lighter in their car can charge the Power Bank while the car is moving. Another charging method is from a mobile phone. Mobile gadgets have appeared on the market that also serve as an external battery.

How do you know if the external battery is charged?

How do you know if the power bank is charged? The standard device has 4 divisions indicating the amount of charge - 25%, 50%, 75%, 100%. The last indicator blinks when the battery is fully charged. However, the simplest budget models may have one or two indicators. When fully charged, the system will turn off the device automatically - there is no need to monitor the charge.

How long does it take to charge a Power Bank?

The time directly depends on two factors: battery capacity and charging method. The standard 5000 mAh capacity when connected to the network will require 5 hours to be fully saturated. If the capacity is twice as large, the time required for charging will also increase. Other methods take much longer; you can only find out how much you need to charge a power bank from a computer or car cigarette lighter by trial and error. The solar-powered device takes the longest to take energy out of thin air.

Features of Power Bank charging

The device must be charged until it is fully, 100% charged. However, when this indicator is reached, you should not rush to turn it off - experts recommend leaving it on for about another hour. At this time, “drip charging” occurs with a weak current, allowing you to maintain the maximum battery capacity for as long as possible.

You can track drip charging if you install an application specially created for this purpose - for Android and Apple.

Fully charge after purchase

There are different opinions on how best to charge a power bank after purchase. Some users argue that this moment does not matter. Manufacturers recommend that the purchased external charger, regardless of its charge level when purchased, be charged to 100%. It is important not to ignore drip charging.

Several charge/discharge cycles at the beginning of operation

When purchasing a Power Bank, you need to “boost” the battery - completely discharge and charge the battery. The same technique can be used if there is a faster than usual discharge.

3 or 4 full cycles of discharging and charging will rewrite the battery statistics.

Always charge your external battery to 100%

Users and manufacturers unanimously claim that modern Li-Ion batteries do not have the disadvantage of the previous ones - the memory effect. Nevertheless, experience shows that this effect still exists, although it is less pronounced than with other types of batteries. Therefore, charging an external battery can be interrupted only in the most extreme cases, and in other cases, wait until the charge is completely 100% and withstand the period of trickle charging.

Why can't you completely discharge the battery?

However, it is not recommended to completely discharge the device to zero constantly - this will shorten the battery life.

You need to charge the battery when the charge level drops to 10-20% charge.

Depending on the model, this can be recognized by the indicators, seen on the screen, or determined by eye using the LED indication.

Sometimes it needs to be discharged

If you do not use the battery for a long time, then...

If you do not plan to use the external charger for a long time, it should be left to “rest” half charged. Full charging and discharging will negatively affect the service life.

Use original chargers

What kind of charger should I use to charge the Power Bank - any or a special one? It is extremely important to use original chargers for this device!

If this is not possible, it is important to choose those that match the characteristics of the Power Bank. Buying cheap accessories can result in expensive gadget repairs.

Avoid overheating the device

It cannot be charged in direct sunlight (except for models with a solar battery). You also need to make sure that it does not lie on the battery or running gadgets, or near a heating radiator.


In order for the Power Bank to serve for a long time, it is important to ensure that it does not overheat.

Conclusion

It is important not to use the Power Bank in the cold - low temperatures significantly reduce the battery capacity. If all operating rules are followed, an external charger can serve its owner for a long time, for example, such well-known manufacturers as Xiaomi, Yoobao, Pineng provide a guarantee of 500 cycles, which equates to 7-8 years of active use.
