After 2-3 years of work, almost any smartphone loses its battery capacity. In this case, during the day may require recharging at least once. On the road, on a business trip, this problem becomes especially acute. This is also true in field conditions, where communication is especially necessary, because the phone may be needed in an unforeseen situation. To solve this problem, a separate class of chargers appeared - crib banks.
Why do we need a bank?
A power bank is an external battery recharged from the mains and storing an electrical charge for another device. The battery is very convenient to use and only requires a USB cable with a microUSB connector (or any other plug for a specific device).
The main advantage of the bank - Compatible with almost all devices and gadgets. The simplicity and compactness of the bank made it almost a necessity for those people whose work is related to travel. In addition to the phone, a power bank will help you to charge: a wireless camera, wireless headphones (at least though), a smart watch, a stand-alone lamp, a WiFi amplifier, a digital cigarette and other gadgets. By the way, and numerous "" it is convenient to charge from the compact "banks" than to be tied to the outlet.
How does the bank work?
The battery converts voltage with a 3.6-\u003e 5V converter. Thus, the output voltage is 5V, with a current of up to 0.8A. Charging of the bank can be made through a network adapter, or from a computer via a USB port (voltage 5V).
Varieties
As a basis for the bank, modern manufacturers offer:
1) Lithium-ion batteries (Li-Ion)
Pros:
- large capacity (up to 3000 mAh);
- output voltage 3.6-3.7V;
- up to 1000 charge cycles;
- low weight and compactness;
- low self-discharge coefficient;
- no memory effect.
Minuses:does not like overheating, so be sure to be equipped with overheating protection.
2) Lithium polymer batteries (Li-Pol)
Pros:
- flat or rectangular shape;
- small weight;
- high energy density per unit volume;
- no memory effect.
Minuses:
- higher cost;
- protection against overheating and fire (additional circuit) is required;
- there is a possibility of battery failure at very deep discharge.
- From the battery capacity in milliampere-hours (mAh), depends on the type and size of the charger. Choose the capacity of the bank depending on the capacity of the battery of the gadget for which you are buying an additional battery. For example, for a smartphone - from 2500 mAh, for a tablet - from 5000 mAh.
- No bank can give 100% of its capacity! Take this into account when calculating how many times you can charge your device using this device without charging the bank.
- The current is an important point when choosing a bank, as batteries with a higher current strength (2A) will charge faster. For some users, time is extremely important. Current range of models of banks on the market: 0.5-2A.
- If you have to recharge several devices from the bank at once, pay attention to the number of USB ports with which the external battery is equipped.
In port banks with two ports (1A and 2A), port 1A is provided for phones and small devices (for example, Bluetooth headphones), port 2A - for professional cameras and tablets. However, modern devices have long been equipped with controllers that regulate the supply of charging energy and you can (almost) not worry, charging with a 2-ampere charging device, in which the standard memory has 1A.
- For the convenience of users, on many models of banks, there are informational light indicators in the form of LED or LCD screens. The first option is less informative, with high data accuracy; often has the form of circular indicators. LCD screen: high-precision, provides the user with more information about the charge of the bank, the process of charging each connected device, air temperature.
- The weight of the device and its capacity (the number of internal batteries) must be related. On the market there are fake models of banks with artificially high weight. Moreover, these manufacturers indicate the maximum capacity of the battery. In order not to be deceived, you need to know: a powerful trust bank weighs about 300 grams. Every 5000 mAh weighs about 100 grams.
- It is recommended to buy only certified banks, as careless manufacturers save on device protection, which can lead to a rapid failure of the device and harm the health of the user.
- When choosing a power bank, carefully inspect its case (aluminum or plastic) for damage.
- Some models have a built-in LED-flashlight, which can be useful.
- Trekking fans should know that there are crib banks with built-in solar panels to power solar energy.

Be careful when buying: purchase protected models with real capacity that will last for a long time and will not harm your device.
With frequent power outages or lack of access to outlets, there is an urgent need to charge mobile phones, computer and digital equipment. All this can make you refuse to listen to music, read e-books, access the Internet through a tablet or laptop, calls from phones. If you do not want to depend on the circumstances, you should take care to purchase a portable charger in advance. This rating will help you choose the best external batteries taking into account the battery capacity, functions, ergonomics and other characteristics.
The most famous brands on our list are Canyon, Huawei and Xiaomi, and you can also call them the most expensive ones. With a small budget, Iconbit, Molecula and Romoss will help out. The rating also included the Russian firm Defender. From young companies that create digital equipment and accessories to it, recognized Xiaomi, Iconbit and Hiper. As always, predominantly Asian manufacturers took the lead.
Let us dwell on each manufacturer in more detail:
- Canyon - produces mobile and computer accessories, the main target audience of the company is youth. It relies on the creation of high-capacity batteries, but in the range there are less powerful options.
- Xiaomi - the manufacturer is widely known, as it is widely known in the world for high-quality assembly of products. He has been working since 2010 and offers record-breaking and lightweight Powerbanks.
- Iconbit - The company is quite young, opened in 2005, it can find models of both medium and high power. It can be seen that it cares about the convenience of users, equipping the products with a charging indicator, the possibility of connecting several devices to them simultaneously, etc.
- Huawei - one of the oldest companies in China, organized in 1987. There are products for both mobile devices and PCs.
- Romoss - Offers all charging tablets, laptops, phones, MP3 players, e-books. The products are divided into 6 series: Domino, Polymos, Solo, Sailing, Sofun and EnCase.
- Hiper - an international leader in the consumer electronics industry niche. The collection of the company includes 13 different series, which also include convenient charging charms. The company's products do not surprise with a large capacity, successfully supplying only small equipment.
- Defender - this brand cannot boast a solid range, its line for 2017 includes only 8 types of different models. In this case, emphasis is placed on the convenience of their operation, which is manifested in the ultra-thin body, built-in flashlight and other nuances.
Such gadgets are divided mainly into lithium-ion (Li-Ion) or lithium-polymer, their capacity ranges from 1600 to 26 000 mAh and above. The higher this figure, the more expensive the device. The average weight of the product is 250 g, its body is made mainly of metal. The optimal current strength is about 3 amps. Classic versions have one USB port, and universal ones have several, usually 2-3 pieces.
Rating best external batteries
Traditionally, the most worthy candidates were selected based on the analysis of user feedback and expert assessments. The priority was the build quality, convenience and efficiency of use of the product, its brand and cost. The final decision was made taking into account the following characteristics:
- Charging time;
- The number of connected devices;
- Type of chargeable equipment;
- Dimensions - weight and dimensions (width, height, thickness);
- Battery type;

Xiaomi Mi Power Bank 10 400
In this category, this model was noted first of all with a faster full charge in comparison with other “brethren”, for this it is enough 5.5 hours. Pleasant impressions and leaves a robust aluminum case, not beating and not scratched. Do not lag behind them and the battery of the modern type of Li-Ion, almost no "memory effect". They provide power of 10,400 mAh, which is an average value, but which is quite enough to provide power to iPhones and other smartphones, music players, and tablets. But, alas, it’s impossible to use this model at sub-zero temperatures, and it’s not very convenient to carry around with you because of its weight of 250 g. But with its design, users are more fortunate.

- To power a laptop, you need a device with a power of output current above 2A. In such a case, you will need an Iconbit FTB20000PB battery.
- Those who are often on the road and use tablets will suit Hiper SP
- Holders of "weak" phones, who need to charge only them, can be limited to Romoss Solo.
- If you need a universal device for all occasions, choose Defender Lavita 20000.
- Look for a product with a good value for money - look at the Huawei AP007.
- If the device has to be often taken with you, then it should be light, and here it is already the Canyon CNE-CPB78DG.
What brands produce "serious" devices, what "surprises" a buyer can expect when they buy them, all about the pitfalls when choosing a product - you will learn about all this from the following video:
All the best external batteries were included in our rating based on objective ratings of users and experts. There are a lot of companies producing portable chargers on the market, but the models shown here are the most demanded and of high quality.
Battery Power Bank is a portable charger that is compatible with all currently popular gadgets that have a USB connector - smartphones, music players, tablets. In fact, it is a renewable removable battery that connects with a wire if necessary. Internal reserve device replenishes through a cable connected to a laptop, computer or network adapter.
Deciding to buy a Power Bank battery, you should pay attention to a number of characteristics that will help you choose the right model. First of all, it is the capacity of the device, that is, an indicator of how much charge it can accommodate and for how many connection cycles it has been calculated. It can be a device for one-time or for multiple replenishment of energy. Power Bank external batteries use traditional lithium-ion batteries or relatively recently developed lithium-polymer batteries. The latter are more capacious with small sizes, but their price is higher.
Depending on how many devices you plan to use with charging Power Bank, you can choose a model with one, two or more USB ports. The combination of several ports is more convenient, since it allows simultaneous charging of the smartphone and tablet. You should not worry about the fact that some of the devices will not receive enough energy. Battery controllers regulate the voltage and current in each output. The range of PowerBank chargers from different manufacturers are also available with additional options.
The remaining reserve can show a light indicator. The display, in addition to displaying the battery level, can show the exact number in percent, the charging process for each connector, and the air temperature. Some external Power Bank batteries are equipped with a bright flashlight.
We constantly monitor the level of service and product quality. We would be grateful if you leave a review about the purchased product section Power bank.
Having trouble picking a Power Bank? We will help you make the right choice.
Recently, Power Bank devices have become very popular, although a few years ago very few people knew or heard about them. This is associated with an increase in the technical characteristics of mobile devices and tablets (without which most people no longer think of their life), with their more active energy consumption and our greater dependence on them. An external portable battery solves all problems with the lack of a standard battery of any device. Many manufacturers have paid attention to this fact and with the growing popularity of these devices, more and more new batteries are being released onto the market, which often do not differ much in their technical characteristics, but can be confusing in the choice of people who are not particularly aware of their parameters. We offer to attention a few 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 to choose your ideal "assistant".
1. The first and most important thing to pay attention to is the manufacturer. It should be understood that Power Bank is a complex technical device, which consists not only of lithium-ion batteries, but also of other elements: a power controller, a processor, indicators, chips, a case, 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 for normal operation with your gadget, so as not to burn it, not to burn yourself, to work properly for a long time and not to be discharged. Systems of protection against voltage surges, free-discharge, recharging, etc. are divided. The battery case is also an important thing, it must be shock-resistant. What can we say about the fact that low-quality Power Bank can be dangerous for your health. A good external battery is like a Mercedes, which will never let you down, and for which special care is not needed, but there are also viburnum frets on the market, which attract with their price, but are deprived of all technical innovations and can fail. the most inopportune moment.
So, the first thing you need to select manufacturers, devices that meet all modern safety standards and that use modern batteries and the latest components. A huge mistake of unaware buyers is that they often choose an external battery, on which there are no marks of the manufacturer and even the usual trademark logo.
Our site contains a list of the main and best manufacturers of world-class portable devices. They have already gained 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 the boxes, they use holographic stickers with serial numbers, with which any user on the official website of the manufacturer can verify the authenticity of their device.
2. The second question is battery capacity. The capacity of modern Power Bank ranges from 2000mah to 20000mah and more. When choosing capacity you need to be guided by your lifestyle. High-capacity batteries require more time to recharge, and also have more weight. Such models are recommended for those who are often on the road (be it a long trip, a trip or a business trip) and do not always have the opportunity to use a power outlet.
The average batteries with a capacity of 8000-12000 mah are the most popular and are suitable for most. Their weight is about 250 grams and, having small dimensions, they fit perfectly in your pocket, without causing great inconvenience. Their charge will last for 2-3 days with active use of the smartphone, and from the network the battery itself will be charged overnight.
Batteries with reduced capacity 2000-5000mah are great for lovely ladies. As a rule, girls are not so actively consuming the charge of their smartphone, and a small compact charge will easily fit even in a cosmetic bag. Note that this capacity segment is the most diverse in terms of design, so that 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 chase the maximum capacity, and on such sites they recoup, selling fakes, allegedly with a capacity of as much as 50,000 mah!
Data: no normal manufacturer produces more than 20 batteries 000 mah; On the Internet, you will not find a single test of such a battery, where its claimed capacity of 50000 mah would correspond to the real one. Such a battery would be too large and heavy, it would be inconvenient to carry it with you, and with such a weight (more than 1 kg), dropping it could damage the batteries. You can write anything on the battery, few of the buyers test them later. Such sellers profit from the ignorance of people, offering a super powerful battery and minimal dimensions. Such super batteries have not yet been invented, if you need a large capacity, just buy a few good batteries at 20,000 mah.
3. Functionality.
Batteries also differ in this. We list the main functions that are very convenient, but not mandatory:
a) Additional USB port. Almost all batteries with a capacity above 10,000 mah are supplied with two USB ports of different currents. This is done so that you can charge two devices at the same time. The USB port with a power of 2A is more suitable for tablets, with it it will charge twice as fast as from port 1A.
b) LED flashlight - a nice bonus that can be useful, for example, during a hike, or if you have to read in the dark.
c) The digital charge indicator is a very necessary thing, but at the end of 2014 from manufacturers, only Pineng 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 the remaining charge of your Power Bank, than just a flashing light bulb. Recommended!
4. Design and shape. In terms of design, everything is the same as with phones - each manufacturer tries to create something new, even more attractive and unusual, but at the same time, each has its own style. Note that the company Emie specializes in the design of its devices and doesn’t really pursue technical characteristics, but in terms of sales this young company is already catching up with the market leaders.
In the matter of choosing the 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 enclosures are made of plastic that resembles a metal that is more pleasant to the touch and more resistant to external abrasions.
Having decided on the manufacturer, deciding what capacity you need and what functionality you need, it remains only to choose a design. Here is a matter of taste. In the rich line of external portable batteries for each customer will find a device for the soul.
5. Compatibility.
Very often, people ask if a particular portable battery is compatible with their particular smartphone. We want to pay attention that all modern devices: phones (iPhones and android smartphones), tablets, players, cameras, cameras, etc. and etc., do not differ in special power settings, so 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 charge itself).
IMPORTANT! In addition to poor-quality external portable batteries, a huge number of fakes appeared on the market.
What is wrong with a fake? Often the declared capacity does not correspond to the real one. It is very easy to check by the weight of the battery. On average, a good battery with a capacity of 10,000 mah weighs 250 grams, and 20,000 mah weighs 450 grams. If you notice a strong discrepancy in weight, then you probably have a fake. With a visual comparison of the original and a fake, you can find many differences, but without such an opportunity, you will hardly notice.
A poor battery can burn your gadget or, even worse, harm your health. Consciously approach the choice of Power Bank!
