Powerbank choice. Seven of the most capacious and high-quality external batteries
There are situations when a gadget is discharged at the most inopportune moment, and there is no way to charge it due to the lack of an outlet nearby. In such a case, use a Power Bank (external battery), which can easily help restore charge on a smartphone or other device that can be charged via USB.
What is a Power Bank?
Power bank is a popular device that is convenient to take with you on trips, trips, as well as to work or school. Due to the large number of models, characteristics, external solutions and dimensions, the task of choosing a suitable device becomes difficult. Therefore, before purchasing it, it is recommended to independently understand the main selection criteria. This will help you avoid mistakes and choose an external battery that is ideal for your smartphone or other gadget.
A power bank, also known as an external or portable battery, is a battery that can charge gadgets such as a tablet, smartphone, e-reader, camera and other devices that can be charged via a USB cable. The battery itself also requires periodic charging, which is carried out through an outlet or computer.
Such a device is capable of storing accumulated energy for a long time. That is why it is very convenient for traveling, in places where there is no constant access to power.
Inside the external battery there are several storage elements connected to the controller board. The board contains one or more connectors for charging gadgets.
For maximum compatibility with as many devices as possible, the Power Bank has a universal USB 2.0 connector.
Battery capacity
When choosing a device, special attention should be paid to its capacity. It is measured in units such as milliampere-hour (mAh). It is these values that will help determine which gadgets can be charged by a particular external battery. The larger the capacity of the Power Bank, the longer it will be able to charge portable devices.
To choose the right device, you first need to determine how many full charges it should last for. Then the resulting figure should be multiplied by the gadget’s battery capacity and by a factor of 1.5.
You should not blindly trust tables that indicate battery capacity: an external battery with a capacity of 10,000 mAh is not capable of charging a smartphone 3 times, which has a capacity of 3,100 mAh. In the best case, charging will last for 2.5 times, and in most cases – for 2 times.
This is explained by the fact that the voltage of the Power Bank is 3.7 V and, depending on the current charge of the device, can fluctuate up or down. Therefore, the voltage first increases to 5A to comply with USB standards, then it flows through the cable to the device being charged, after which the charge controller on the gadget reduces the voltage to the level required to fully charge its battery. Due to double conversion, 20-30% is lost.
Current strength
The second important criterion when choosing an external battery is the current strength, since it determines how quickly the gadget will charge (the higher it is, the faster the charging occurs). To avoid any damage to the device being charged, you need to find out what current strength will be optimal for charging its battery. This information can be found by reading the label of the “native” charger that comes with the gadget.
- Devices up to 1A are very rare and are only suitable for charging simple phones (it is too weak for smartphones).
- 1-1.5A - this indicator is ideal for recharging smartphones. With lower current values, the charging process will be significantly delayed, and if you also use a smartphone with a capacitive battery, the charging indicator may remain in one place. It is not recommended to connect an external charger with a current of 2A to the device without first specifying how appropriate this will be.
- 2-4A is a suitable option for tablets. These indicators allow you to quickly charge your tablet computer.
There are smartphones with a built-in controller, which, when supplying a current higher than necessary, optimizes it to acceptable levels. These are safety measures provided by the manufacturer.
The electronics market also offers external batteries with express charging functionality. When this device operates, the voltage increases and the current decreases, which allows you to charge the smartphone only halfway (50-60%) within 30-40 minutes.
Functional Features
The functionality of each external device for charging gadgets is individual. The richer its functionality, the more practical the external battery. These criteria include:
- Availability of exits. For ease of use of the device, the current strength is indicated next to each output. This is necessary to make it easier to determine which socket a particular gadget can be connected to.
- Availability of adapters and cables. Equipping the external battery with additional charging cords will not be superfluous. This is due to the fact that the universal connector is not suitable for old-type mobile devices, and additional cables will do the job perfectly.
- Digital charge level indicator. A very useful solution that allows you to accurately navigate the amount of remaining energy. When choosing a portable battery as an additional one for recharging your phone, this function should be considered immediately after the main ones.
- Additional USB ports. Their presence will come in handy if you need to charge several devices at the same time.
- LED flashlight. It may be useful in the dark to illuminate the socket to which the external battery will be connected.
- Availability of solar panel. In addition to recharging the Power Bank from the network or other sources, the presence of solar power will allow you to accumulate additional energy in the device from the sun's rays. It should be mentioned that you should not expect much energy storage from such a panel.
Compatibility
When choosing a portable charger, you need to pay special attention to the input current for the gadget and select a model so that its output voltage matches it.
You can find out information about what input voltage is required to fully charge the device by studying either the data on the mains charger that came with the gadget, or in the instructions for it. For most gadgets such as tablets, smartphones, action cameras, navigators, the most common DC voltage indicator is 5V (5V DC), which corresponds to USB parameters.
Typically, the current requirements are not so stringent. This is due to the fact that when charging a device with a lower current requirement than an external battery, the controller is activated, which equalizes the current to optimal levels.
Charging Features
The simplest external batteries have one USB output, while more advanced ones have two, often with different output currents. But there is one caveat: when charging two smartphones at the same time, a minimum current will be supplied.
The board built into the Power Bank also has certain functions that not only simplify the use of a portable device, but also maximize its service life by properly organizing the charging process. This:
- Automatic power off. A convenient option for people who do not have time to monitor the charging progress. They can leave their gadget connected to a portable device for a long time without worrying about its condition.
- Load shedding. This is the same option, only located at the other end of the portable battery. In this case, the automation monitors the charging of the battery itself and turns it off as soon as the device restores its potential.
When choosing a Power Bank, you should check with your consultant how the external device itself will be recharged. There are batteries that are charged not only from a power outlet, but also through a computer or phone port via micro-USB, have the already mentioned power source in the form of a solar battery, or are charged from the cigarette lighter in a car.
Other selection criteria
Other criteria for choosing a Power Bank device are:
- Weight and dimensions. In this case, the formula is simple: the weight directly depends on the capacity of the external battery (the larger the capacity, the greater the mass). This indicator is also influenced by the type of battery used: a lithium-ion (Li-ion) battery will have more mass than a lithium-polymer (Li-pol) battery with a similar capacity. It is also impossible to ignore the main material from which the case is made. For example, an aluminum case will be much heavier than a plastic one.
- Device design. Thanks to the large selection of models and extraordinary design solutions from manufacturers, potential buyers have a wide choice of external chargers. There are external batteries in the form of a milk carton, cartoon characters, animals, car models.
- Manufacturer. Since the Power Bank is considered a high-tech device that has a number of protective systems that are necessary to ensure the functionality of the gadget, it must effectively neutralize all possible threats that could harm the gadget while charging. It follows from this that you should not buy a device from an unknown manufacturer, as there is a risk of purchasing a low-quality external battery. Subsequently, this may cause a breakdown or failure of the battery of the gadget being charged. It is recommended to buy products only from trusted brands and be wary of too low prices.
- Body and material. The battery case can be made of plastic, metal or polycarbonate. The listed materials do not differ much in terms of practicality; the only nuance is the difference in weight. So, the metal case is heavier than the others. If a Power Bank is purchased for use in extreme conditions, it is recommended to select an external battery made of impact-resistant materials (such as aluminum), and also select and use rubberized cases. In addition, it is worth paying attention to the presence of reinforcing elements on the body.

Summer is a time for active recreation. A time when you want to spend your free time not at home, but in the open air. At such moments, it is unpleasant to realize that our gadgets seem to be tied to an outlet. But a solution was found - a portable charger, simply called Power Bank in foreign language.
An accessory for those who lack the inherent autonomy of the device. At the same time, it doesn’t matter which device requires emergency recharging. You can charge a smartphone, tablet and even a laptop, not to mention other devices that require 5V! A selection of interesting models below the cut!
How to choose a Power Bank
Despite its apparent simplicity, the variety of models produced can be perplexing; let’s look at the key parameters in more detail.Main characteristic - portable battery capacity. There are a variety of options on the market: from the ridiculous 2,000 mAh to the extreme 30,000 mAh and above. The option with a capacity of about 10,000 mAh looks universal. This volume will allow you to easily take the device anywhere, as an emergency power source. And when traveling, it will provide more than one autonomous day.
Input and output power- a parameter that directly affects the charging time of the battery and devices connected to it. Options with an output current of 1A are no longer worth considering; most smartphones and tablets have long consumed at least 2A. This option is optimal for most gadgets. The development of fast charging technologies has had an impact on portable batteries; models that support one or another standard are becoming more and more common. The choice of a specific model depends on the fleet of devices that require recharging.
Most of the presented models use microUSB, which is actively being replaced by the newest USB Type-C. Unusual solutions with Lighting from Apple, which greatly affects the final cost of the product.
With all the variety of models produced, we can single out the best offers. Read on about portable batteries, which we are not ashamed to recognize as the “golden mean”.
Xiaomi Mi Power Bank Pro and Mi Power Bank 2
The second generation of batteries has absorbed the best from its predecessors. In the selection of the best portable batteries, it is impossible to do without products from Xiaomi. This company has made a huge contribution to the popularization of such accessories. This was marked by the release of a line of batteries of different capacities at reasonable prices.
The design of Xiaomi portable batteries has long been established - the body is made of anodized aluminum, with plastic covers at the ends. The appearance is impressive, but in practice it turns out that you can’t do without a cover. Otherwise, the aluminum case will quickly lose its luster, and most importantly, it will scratch everything around. Fortunately, the company itself produces cases: simple silicone ones for microUSB modifications and a leather pocket for Pro. The battery weight is 223 grams, with a case the figure is close to 300 grams.
In the second generation, the company abandoned the usual elements of the 18650 format and finally switched to lithium-polymer Lishen. This had a positive effect on the dimensions and shape; a thin body with a larger area is much more convenient to carry in your pocket and hold in your hand along with a smartphone.
The main functional feature of the new models is support for two-way Qualcomm Quick Charge 2.0. In accordance with the standard, the device is capable of delivering up to 18 W of power. When using a compatible power adapter, battery charging time is also significantly reduced to 2-3 hours.
Unlike other batteries, Xiaomi is capable of charging small accessories with a small current: headsets, fitness bracelets, wireless headphones, etc.
Traditionally for Xiaomi, 10,000 mAh models have only one USB output. A modern USB Type-C is provided for charging the battery. When, like in Mi Power Bank 2, it’s an old microUSB.
Rombica NEO ES100
The company is a large manufacturer of accessories from Singapore. Portable batteries occupy a significant share in the assortment. Of all the variety of ten-thousanders, the NEO ES100 model stands out for its original appearance. The practical housing made of soft-touch plastic hardly needs a case and is immediately ready for use. In addition, the device weighs only 205 grams.
There is no support for newfangled fast charging standards here. At the same time, the battery is suitable for any smartphones and tablets: the maximum output current is 2.1A at 5V, and this is quite enough. The battery itself is charged at 5V/2A - a common solution.
I’m glad that the company has equipped its product with two USB outputs; the battery is capable of simultaneously charging two devices. At the same time, traditional microUSB is used to recharge the battery.
Samsung EB-PN930
Samsung's portable battery supports Qualcomm Quick Charge 2.0, which is compatible with the company's latest flagships. When using a QC 2.0 charger, the battery will charge quickly. There is only one USB output port, the input port is USB Type-C.
Portable batteries with Lightning
Finding a portable battery that charges via microUSB or USB Type-C is a more or less simple task. Another thing is to find a device that charges via Lighting.Remax Perfume 10000 mAh RPP-27
At first glance, it looks like a typical portable battery in a plastic case weighing 205 grams.
In addition to the original design, the model is notable for the presence of a Lighting connector, which will allow owners of Apple equipment to use one cable for all devices. microUSB is also in place, the user always has a choice! At the same time, the maximum input current is only 1.5A. The output includes two USB connectors of 5V/2.1A.
Teclast T100UC-S
An interesting alternative from a Chinese online store. Teclast, a manufacturer known to fans of Chinese tablets, could not stand aside and released a hybrid portable battery. The usual aluminum block weighing 240 grams, but not without some tricks. Unlike competitors, Teclast is equipped with a percentage indicator of the remaining charge, instead of the traditional four indicators.
You can charge the battery via microUSB or Lighting. In the first case, the input current will be 2A, and in the second 1.5A. The output is two USB, 1A and 2A at 5V, no fast charging technologies are provided.
Power bank for laptop
An interesting solution for summer travel is a portable battery with a laptop charging function.Rombica NEO PRO 280
A universal solution that supports laptops from most well-known manufacturers. Unlike the above models, the Rombica accessory is a hero in an aluminum case weighing 830 grams.
The battery capacity is 28,800 mAh at 3.7V, which corresponds to 106.6 Wh. Two USB ports output 5V/1A and 5V/2A. And a special connector for charging laptops supports the following modes: 12V, 16V, 19V / 3.2A. Included is a set of cables for most modern laptops, including: Acer, Apple, HP, Lenovo.
To charge a battery of this size with a standard 5V/2A adapter will take a very long time. Fast charging technologies will only improve the situation a little, so the manufacturer has chosen an alternative path. The Rombica portable battery is charged from its own 15-19V/1.8A power adapter. A non-universal adapter is an inconvenience, but otherwise the issue with charging speed cannot be solved.
Rombica NEO PRO 180
The company also has a more compact model in its arsenal. The battery capacity is 18,000 mAh, and the weight is 570 grams, that is, the relief is proportional to the reduction in capacity. Other characteristics are similar.
Romoss eUSB sofun 9
Romoss is a company that specializes in producing a variety of chargers. Portable batteries occupy a special place in the assortment. The eUSB sofun line is designed specifically for laptops. The older model is an unremarkable device made of glossy plastic weighing 570 grams.
The battery capacity is 23,400 mAh at 3.7V, which corresponds to 86.6 Wh. The battery is equipped with two USB ports for charging mobile equipment: 5V / 2.4A and 5V / 1A. To connect laptops, proprietary eUSB technology is used; devices requiring up to 65 W are supported. The kit includes a set of 15 adapters for a variety of laptops.
The smallest portable battery with laptop support in the line. The capacity is only 10,400 mAh at 3.7V (38.5 Wh), and the weight is 262 grams. The model is equipped with one eUSB port, which supports laptops up to 45 W and other mobile equipment (5V / 2.1A). The main difference is charging the portable battery via microUSB using the usual power adapters (5V / 2.1A).
Are you having difficulty choosing a Power Bank? We will help you make the right choice.
Recently, Power Bank devices have become very popular, although a couple of years ago few people even knew or heard about them. This is due to the increase in technical characteristics of mobile devices and tablets (without which most people can no longer imagine their lives), their more active energy consumption and our greater dependence on them. An external portable battery solves all problems with the lack of standard battery of any device. Many manufacturers have paid attention to this fact and, with the growing popularity of these devices, they are releasing more and more new batteries onto the market, which, often, do not differ much in their technical characteristics, but can confuse people who are not particularly knowledgeable about their parameters in their choice. We bring to your attention several important points with the help of which you can answer important questions that arise when choosing an external battery, and significantly reduce the list of devices for choosing your ideal “assistant”.
1. The first and most important thing you need to pay attention to is the manufacturer. You need to understand that a Power Bank is a complex technical device that consists not only of lithium-ion batteries, but also other elements: power controller, processor, indicators, microcircuits, housing, etc. Each of these elements is important.
The device is called a "portable charger" and not just a "battery" because it provides a number of protective systems to function properly with your gadget so as not to burn it, not to burn yourself, to work properly over time and not to discharge. They separate systems for protection against voltage surges, freezing, overcharging, etc. The battery case is also an important thing; it must be shock-resistant. What can we say about the fact that a low-quality Power Bank can be dangerous to your health. A good external battery is like a Mercedes that will never let you down and doesn’t require special care, but there are also “Kalina frets” on the market that attract with their price, but lack all the technical innovations and can fail in the most inopportune moment.
So, first of all, you need to choose manufacturers whose devices meet all modern safety standards and who use modern batteries and the latest components. A huge mistake made by uninformed buyers is that they often choose an external battery that does not have any manufacturer’s markings or even the usual brand logo.
Our website contains a list of the main and best manufacturers of world-class portable devices. They have already managed to win the trust of their customers. All these companies have international quality certificates and provide guarantees for their devices. In addition to branded packaging and seals on boxes, they use holographic stickers with serial numbers, with which any user on the manufacturer’s official website can verify the authenticity of their device.
2. The second question is the battery capacity. The capacity range of modern Power Banks varies from 2000mah to 20000mah and more. When choosing a container, you need to be guided by your lifestyle. Higher capacity batteries require more time to recharge and also weigh more. Such models are recommended for those who are often on the road (be it a long trip, travel or business trip) and do not always have the opportunity to use an outlet.
Medium batteries with a capacity of 8000-12000 mah are the most popular and suitable for most. Their weight is about 250 grams and, having small dimensions, they fit perfectly in your pocket without causing much inconvenience. Their charge will last for 2-3 days with active use of the smartphone, and the battery itself will be charged overnight from the mains.
Low capacity batteries 2000-5000mah are great for lovely ladies. As a rule, girls do not use up the power of their smartphone so actively, and a small compact charger can easily fit even in a cosmetic bag. Note that this segment of the container is the most diverse in terms of design, so any girl will be able to choose exactly the device that will fit into her style and will pleasantly surprise her friends.
External batteries50000 mah. This is a separate topic. Very often people are chasing maximum capacity, and sites like this take advantage of them by selling counterfeits that supposedly have a capacity of as much as 50,000 mah!
Data: no normal manufacturer produces batteries over 20 000 mah; On the Internet you will not find a single test of such a battery, where its declared capacity of 50,000 mah would correspond to the real one. Such a battery would be too large and heavy, it would be inconvenient to carry, and with such a weight (more than 1 kg), dropping it could damage the batteries. You can write anything on the battery, few buyers then test them. Such sellers profit from people’s ignorance by offering a super powerful battery and minimal dimensions. Such super batteries have not been invented yet, if you need high capacity, just buy some good 20000 mah batteries.
3. Functionality.
Rechargeable batteries also differ in this regard. Here is a list of the main functions that are very convenient, but not required:
a) Additional USB port. Almost all batteries with a capacity above 10,000 mah are equipped with two USB ports of different current strengths. This is done so that you can charge two devices at the same time. A USB port with a current of 2A is more suitable for tablets; with it it will charge twice as fast as from a 1A port.
b) An LED flashlight is a nice bonus that can be useful, for example, on a hike, or if you have to read in the dark.
c) A digital charge indicator is a very necessary thing, but at the end of 2014, only Pineng is the only manufacturer that uses it. By the way, Pineng specializes in the latest developments in the field of portable power. Agree, it is much more convenient to see the exact percentage of charge remaining on your Power Bank than just a flashing light. We recommend!
4. Design and shape. In terms of design, everything here is the same as with phones - each manufacturer is trying to create something new, even more attractive and unusual, but at the same time, each has its own style. Note that the Emie company specializes specifically in the design of its devices and does not particularly pursue technical characteristics, but in terms of sales, this young company is already catching up with the market leaders.
Regarding the choice of a case - plastic or metal, we would like to note that the current strong plastic is not much inferior in strength to metal. Many Power Bank cases are made of metal-like plastic, which is nicer to the touch and more resistant to external abrasions.
Having decided on the manufacturer, deciding what capacity you need and what functionality you require, all that remains is to choose the design. It's a matter of taste here. In the rich line of external portable batteries, every buyer will find a device to their liking.
5. Compatibility.
Very often people ask whether a certain portable battery is compatible with their specific smartphone. We would like to note that all modern devices: phones (iPhones and Android smartphones), tablets, players, cameras, cameras, etc., do not have special power parameters, so the Power Bank is suitable for any device!
An external portable battery is not suitable only for devices that have their own external power adapter, so it will not be able to charge the laptop (it can only recharge itself from it).
IMPORTANT! In addition to low-quality external portable batteries, a huge number of fakes have appeared on the market.
What's wrong with a fake? Often the declared capacity does not correspond to the real one. This is very easy to check by looking at the weight of the battery. On average, a good battery with a capacity of 10,000 mah weighs 250 grams, and a 20,000 mah battery weighs 450 grams. If you notice a strong discrepancy in weight, then this is probably a fake. When visually comparing the original and the fake, you can find many differences, but without this opportunity, you are unlikely to notice.
A low-quality battery can burn your gadget or, even worse, harm your health. Be conscious when choosing a Power Bank!
An external phone battery allows you to charge your phone and other devices without even having a power outlet nearby.
The compact Power Bank is an innovative gadget that can charge all user phones “on the go.”
Batteries differ according to three main criteria:
- According to its capacity;
- By type of outgoing current;
- According to the type of battery itself.
Basically, all external chargers are made of plastic. More expensive options are made of metal and a waterproof surface.
However, such batteries are more intended for hiking conditions than for everyday use. For an ordinary user, a plastic Power Bank will be enough.
There are also external chargers for certain smartphone models. They are attached to the phone body.
The disadvantage of such batteries is that they are not universal, and their cost is several times higher than the cost of a good Power Bank, which can charge several user phones at once.
In most cases, batteries must be selected based on such a parameter as capacity. A good external battery for a smartphone should have a capacity of at least 2500 mAh.
For a tablet, an external battery must have a capacity of 5000 mAh. These minimum capacity requirements will allow you to fully charge the gadget at least once.
The current supplied by the smartphone also affects the choice of battery. Basically, all smartphones transmit a current of 1 or 2 Amps.
On the charger that comes with your smartphone, you can read the required voltage that the charger should have.
How to charge a smartphone? To do this, simply connect your phone to an external charger using a USB cable.
The charging process will start automatically. The Power Bank itself needs to be recharged periodically. It is charged from an outlet.
Let's take a closer look at individual models of external batteries for smartphones.
