Compact power bank. Portable battery Power Bank: basic selection criteria, TOP best devices

Modern people prefer to use smartphones instead of tablets and laptops, because they are just as powerful and more compact at the same time. But due to their small size, their battery life is reduced: it is impossible to install a capacious battery in a small case.

To solve the problems that arise because of this, you can purchase an external battery for your phone. How to choose which characteristics to pay attention to and which models are the most popular today, you will learn in the article.

Top external batteries

Why is it needed?

An external battery (also known as Power Bank) is designed to charge a smartphone or other mobile device if there is no access to power supply networks. To do this, the device is connected to a mobile gadget using a special adapter cable.

It is not always convenient to use a second battery to replace the main one. In addition, many modern flagship smartphones have a die-cast body, in which the battery is non-removable. In this case, using Power Bank is the best option.

Principle of operation

An external battery is a set of batteries combined with each other and enclosed in a case, which has a universal output (usually a USB port) for connecting an adapter. For the manufacture of the case, plastic (cheap models) or aluminum is used.

After connecting to the Power Bank of the smartphone, the standard charging process will begin. These steps can be repeated until the external battery is completely discharged. Due to the fact that it has a large capacity, you can simultaneously or in turn charge two or more gadgets, or one mobile device several times in a row.

Specifications

When choosing an external battery for a smartphone, pay attention to the main characteristics that will help you choose a high-quality and durable device.

Capacity

This is the main characteristic that determines the performance of an external battery. It shows how long the device will provide the mobile gadget with energy.

This parameter is measured in ampere-hours (Ah) or milliampere-hours (mAh). In order for the Power Bank to work effectively and without any problems with it, its volume must be at least 2 times the capacity of the battery of the device that it recharges. But the larger this parameter, the better.

The larger the capacity of the external battery, the longer the period of its operation. But at the same time, the time for recharging increases.

In addition, it should be borne in mind that the larger the capacity of the selected device, the more expensive it will cost. The golden mean is 6000 mAh models. A Power Bank with a capacity of 15,000 mAh and more is suitable for charging a smartphone or even a tablet.

Current strength

The outgoing current affects the charging time of the device. The higher it is, the faster the smartphone will charge. For a mobile phone, the standard indicator is 800-1200 mA, for tablets, 1500-2000 mA.

Good to know! It is desirable that this parameter coincides with the recommendations of the manufacturer of the smartphone or tablet.

Dimensions (edit)

Please note that the larger the capacity of the external battery, the larger it is, because more batteries are placed inside. But in this case, everyone chooses a model for themselves, depending on the requirements that he makes to it.

For fans of hiking, a Power Bank of large capacity and dimensions is suitable. And for users who recharge their smartphone in order to "sit" in social networks, a compact and less capacious option is suitable.

Don't buy models that offer high capacity in a compact package. These are gimmicks that are used to increase sales.

Peculiarities

Different Power Bank models may have their own characteristics.

1. Number of nests... Some models have multiple jacks for connecting two or more gadgets at the same time. In most cases, they have different outgoing currents: 1000 and 2000 mA for charging smartphones and tablets, respectively.
2. Cable with a set of adapters... Such devices are suitable for new, as well as for old smartphones that do not use Micro-USB or USB Type-C sockets, but other connectors.
3. External battery charging method... When buying an external battery, choose a model that charges via a Micro-USB socket. This will allow you to use a regular smartphone charger to charge it.
   There are Power Bank models with solar panels installed on the case. Basically, they compensate for the effect of self-charging of batteries, but for full charging of the external battery itself, they are not suitable.
4. Battery level indication... The indicator will tell you how much energy is left in the external battery and when it needs to be connected to the mains for charging. This is a convenient option, but it affects the cost of the model.

The best choice

Xiaomi Mi Power Bank 16000

The main advantage of the model is its excellent quality, high reliability and affordable cost. Thanks to the metal body and large battery capacity, you can easily charge the same gadget several times in a row (5 times or more).

The presence of two USB ports allows you to charge multiple devices at the same time, but their close location will not allow you to connect two massive plugs at the same time. In general, this is where the cons of the model end, so it is the best choice to buy.

Advantages

TP-LINK TL-PB10400

Unfortunately, due to the large volume of the batteries, the battery case had to be made square, which is not always convenient in operation. In addition, it is made of plastic, albeit reliable. This has reduced both the weight and the reliability of the Power Bank.

The current strength at the two outputs is different: 2000 and 1000 mA, so you can choose which device and where to connect.

The presence of two USB ports, a flashlight and a battery charging indicator allows you to operate the device comfortably and easily. Although the flashlight is of average quality.

Advantages

• battery;
• charge level indicator;
• 2 USB ports;

Although the cost of Yoobao YB665 is quite high, the set of functions and reliability will allow it to be operated for a long time. In addition, the Power Bank comes with a charger and adapters for the iPhone.

The presence of a flashlight and two USB ports with different outgoing amperage expands the functionality of the model.

Advantages

• frame;
• reliability;
• flashlight;
• 2 USB ports;
• adapters for iPhone;
• battery level indicator.

Flaws

Rombica NEO X100

The top cover of the model is made "under the skin", so Rombica NEO X100 looks stylish and modern. At the same time, the battery is compact, thin and has a large capacity, so it is suitable even for a fragile girl.

The lack of a flashlight reduces the functionality of the Rombica NEO X100. But located at a considerable distance USB ports with different output amperage values ​​provide comfortable charging of several devices at the same time.

With frequent power outages or lack of access to sockets, the question of charging mobile phones, computer and digital equipment arises. All this can make you refuse to listen to music, read e-books, access the Internet through a tablet or laptop, and make calls from phones. If you do not want to depend on the circumstances, you should take care of buying a portable charger in advance. This rating will help you choose the best external batteries based on battery capacity, functions, ergonomics and other characteristics.

The most famous brands on our list are the brands Canyon, Huawei and Xiaomi, and they can also be called the most expensive. With a small budget, Iconbit, Molecula and Romoss will help out. The rating also included the Russian company Defender. Among the young companies creating digital equipment and accessories for it, Xiaomi, Iconbit and Hiper are recognized. As always, the leading positions were taken by mainly Asian manufacturers.

Let's 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 there are also less powerful options in the range.
• Xiaomi- the manufacturer is on everyone's lips, as it is widely known in the world for high-quality assembly of products. It has been operating since 2010 and offers record-high capacity and lightweight Powerbanks.
• Iconbit- the company is quite young, opened in 2005, it offers models of both medium and high power. It can be seen that she cares about the convenience of users, equipping products with a charging indicator, the ability to connect several devices to them at the same time, etc.
• Huawei Is one of the oldest companies in China, founded in 1987. There are products for both mobile devices and PCs.
• Romoss- offers all charges for tablets, laptops, phones, MP3 players, e-books. The products are divided into 6 series: Domino, Polymos, Solo, Sailing, Sofun and EnCase.
• Hiper Is an international leader in the consumer electronics niche. The collection of the company includes 13 different series, which also include convenient chargers-key fobs. The company's products are not surprising with their high power, successfully supplying power to only small equipment.
• Defender- this brand cannot boast of a solid assortment, its line for 2017 includes only 8 types of different models. At the same time, the emphasis is on the convenience of their use, which is manifested in an ultra-thin body, a built-in flashlight and other nuances.

Such gadgets are mainly divided into lithium-ion (Li-Ion) or lithium-polymer, their capacity ranges from 1600 to 26,000 mAh and above. The higher this figure is, the more expensive the device is. The average weight of the product is 250 g, its body is made mainly of metal. The optimum amperage is about 3 amperes. Classic versions have one USB port, and universal ones have several, usually 2-3 pcs.

Rating of the best external batteries

Traditionally, the most worthy candidates were selected based on the analysis of user reviews and expert assessments. The priority was the build quality, convenience and efficiency of the product, its brand and cost. The final decision was made taking into account the following characteristics:

• Duration of charging;
• The number of connected devices;
• Type of equipment to be charged;
• Dimensions - weight and dimensions (width, height, thickness);
• Battery type;
• Design;
• Battery capacity and resource;
• Delivery set (completeness of instructions, length and types of cables);
• Body material.

Particular attention was paid to the compliance of the actual characteristics with the declared manufacturers.

The best small capacity external batteries: up to 10,000 mAh

Here you will not find super powerful portable chargers, but manufacturers do not "break" prices. On average, for 700-1000 rubles, you can buy a pretty decent product that can charge not the most powerful smartphone or tablet once, maximum 2 times.

An option for those who are not used to carrying "bricks" with them, because the device weighs only about 180 g. Users note in the reviews the convenience of notification of the state of charge. But this does not change the fact that its declared capacity (7800 mAh) does not correspond to the actual one (about 3500). The difference is quite impressive, and it can hardly be compensated for by the presence of two USB connectors and a powerful lamp that illuminates well at night. The plastic case also suggests low quality. But in general, this is a good external battery for a budget segment phone, capable of recharging a not very powerful tablet or book 1-2 times without recharging the charge.

Advantages:

• Small;
• Enough for 4-5 iphone charges;
• Built-in flashlight;
• Beautiful design;
• Charges quickly;
• Allows you to connect two devices at once.

Flaws:

• The indicated power does not correspond to the real one;
• The cable breaks.

Romoss solo 5

A solid thing that works flawlessly even with regular use. It doesn't matter what you need to charge - book, player, phone, tablet - it can handle all small gadgets. And this despite the fact that the declared capacity is not so high here, 10,000 mAh. True, you will have to pay for this, since it is not always convenient to carry a 300-gram device with you. In favor of this model is the possibility of recharging it using a laptop and a plastic case that is not afraid of falls and moisture. The battery life is quite impressive - over 300 cycles. It takes about 6 hours to charge the devices, which is pretty good.

Advantages:

• Non-slip and shockproof housing;
• Compact dimensions;
• Charge status indication;
• Compliance of the declared power with the actual;
• Modern type of batteries.

Flaws:

• Small maximum output current;
• Low temperature operating conditions;
• Perceptibly heavy weight.

Chargers from the most renowned brands in their niche were included in this category. Given this and the rather high cost, one can expect better performance from them than from less powerful counterparts.

Xiaomi Mi Power Bank 10 400

In this category, this model was noted, first of all, by a faster full recharging in comparison with other "brothers", for this 5.5 hours are enough for it. The reliable aluminum casing, which does not break or scratches, also leaves a pleasant impression. The batteries of the modern type Li-Ion, which practically do not have a "memory effect", are not lagging behind them. They provide a power of 10,400 mAh, which is an average value, but which is quite enough to provide power for iPhones and other smartphones, players, tablets. But, alas, using this model at subzero temperatures will not work, and it is not very convenient to carry it with you due to its weight of 250 g. But with its design, users were more fortunate.

Advantages:

• Charges devices quickly;
• Enough for 3-4 times;
• High-quality assembly;
• Metal body;
• Automatic shutdown when not in use;

Which external battery is better to buy

Owners of a large number of different gadgets - inexpensive smartphones, tablets, players, e-books, laptops, etc., should choose a model with several connectors and with different output amperage. For recharging not the most powerful phone with 750-1500 mAh, inexpensive products with a capacity of up to 10,000 mAh will be quite enough.

1. To power the laptop, you need a device with an output current greater than 2A. In such a case, you will need an Iconbit FTB20000PB battery.
2. For those who travel frequently and use tablets, the Hiper SP is the right choice.
3. Owners of "weak" phones, who need to charge only them, can be limited to Romoss Solo.
4. If you need a universal device for all occasions, choose the Defender Lavita 20000.
5. Look for a product with good value for money - take a closer look at the Huawei AP007.
6. If the device is often to be taken with you, then it should be light, and here the Canyon CNE-CPB78DG will do.

What brands produce "serious" devices, what "surprises" may await the buyer when buying them, all about the pitfalls when choosing a product - you will learn about all this from the following video:

All the best external batteries have been included in our ranking based on objective user and expert ratings. There are a lot of companies on the market that produce portable chargers, but the models shown here are the most popular and of high quality.

For all mobile devices, autonomy is a weak link. Low energy reserves do not allow the user to fully enjoy the opportunities during the day. If we talk about flagship models, then the active work time can be calculated in several hours. For a long time, society had to carry a charger in a bag and depend on an outlet, but modern power banks have completely eradicated this problem. Different styles and materials of the case, total usable capacity and charging technologies allow you to choose an external battery for a specific smartphone or group of devices.

Among the large assortment, Xiaomi products stand out. The brand's popularity is growing rapidly, and in the production of power banks it can already be called a leader. The company has ensured such a result for itself with an optimal combination of cost and characteristics.

Singaporean Rombica and American Goal Zero were awarded to the premium segment. Both companies make professional external batteries for charging any device. The main feature is the combination of the familiar with the high-tech - solar panels, inverters.

HARPER has successfully established itself in the middle segment with a focus on tourism. The devices have increased durability and functionality for survival in extreme conditions.

The budget segment has always been the most popular, so a large number of Chinese craftsmen work here - Asus, TP-Link and Yoobao. They were joined by the European brand Hiper and the American Canyon. Their main task is to provide users with autonomy, so the devices have a large capacity.

The manufacturer Xiaomi has already made a lot of noise, it is not for nothing that it is often called the "Chinese Apple". The Xiaomi company was able to surprise the weight of the world, and especially China, overtaking all its competitors in sales of mobile devices, despite its young age. As for any Xiaomi products, they are of high quality and affordable prices. Directly Power Bank Xiaomi Mi 2 10000 earned its honorable fourth place precisely for its dimensions, weight, metal body and Quick Charge 2.0 (two-sided) function.

The power bank for your phone allows you to charge your phone and other devices without even having a power outlet at hand.

The compact Power Bank is an innovative gadget that can recharge all user's phones on the go.

Batteries differ in three main criteria:

1. By its capacity;
2. By the type of outgoing current;
3. By the type of the battery itself.

Basically, all external chargers are made of plastic. More expensive options are made from metal and a waterproof surface.

However, these batteries are more for outdoor use than for everyday use. A plastic Power Bank will be enough for an ordinary user.

There are also external chargers for selected smartphone models. They are attached to the body of the phone.

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 is able to recharge several user's 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, the external battery must have a capacity of 5000 mAh. These minimum capacity requirements will allow the gadget to be fully charged at least once.

The amount of current supplied by the smartphone also influences the choice of the battery. Basically all smartphones transmit a current of 1 or 2 amperes.

On the charger that comes with the smartphone, you can read the required voltage that the charging should have.

How do I charge my smartphone? To do this, simply connect your phone to an external charger using the 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.
