How to choose an external battery for a smartphone: cheat sheet from CHIP

How many times have you suffered from your smartphone running out of power at the most inopportune moment? What if you need to make an urgent call or wait for an important message? It’s good if there is an outlet or computer nearby that you can quickly charge your device from. But what if they are not there? The solution is to use an external battery (power bank). The Internet project “Be Mobile” has collected tips that will help you choose the best option for you.

First, let’s define what an external battery is and what its advantages are. An external battery or Power Bank is a portable high-capacity lithium-ion battery that can be used to charge a variety of mobile devices: phones, smartphones, tablets or e-readers. This battery is capable of storing energy within itself for a long time. You can take it with you to work, school, on a business trip or while traveling.

The portable charger can be made in various form factors with a housing made of plastic, polycarbonate or metal. On sale you can find models in the form of boxes, bars, disks, cones and tubes in a variety of colors.

The Power Bank is charged from the electrical network or from any device with a USB output (for example, a computer or laptop).

All external batteries are equipped with one or more USB ports. Modern phones, smartphones or tablets can be charged using a USB cable, which in most cases is included with the device.

Tip 1: look at the capacity of the external battery

The main parameter when choosing an external battery is energy capacity. Everything here is simple and clear. The larger the capacity, the more energy the device stores, and the more expensive it is. Capacity is measured in mAh - milliamp hours.

Currently on sale you can find portable chargers with a capacity ranging from several hundred milliamp hours to several tens of thousands. You can estimate the level of charge you will need based on the battery capacity of your smartphone or tablet.

For example, in an average smartphone the battery has a capacity of 2,000 mAh, in high-performance and expensive models - from 2,500 to 3,000 mAh. This means that a fully charged 5,000 mAh external battery will be enough for 2-2.5 charging cycles. A fully charged 10,000 mAh external battery will last for 4-5 cycles. If portable charging is necessary for your tablet, then you should choose from models with a larger capacity, for example, 20 or 30 thousand mAh.

Currently produced portable power sources use lithium-ion or lithium-polymer batteries. Depending on the type and design, the nominal battery output voltage may vary (3.7, 4.2, or 7.4 V), while the standard USB bus voltage is 5 VDC. Obviously, in this case, a battery with a capacity of 2000 mAh with a nominal voltage of 3.7 V, even under ideal conditions, will not work for even an hour and a half when powering an external load connected via a USB bus and consuming a current of 1 A. In addition, the amount of electricity that can be stored Batteries having the same capacity but different voltage will vary.

Tip 3: trust, but check, because the declared capacity does not always coincide with the real one

Another important point is the actual capacity of the Power Bank. The fact is that many manufacturers embellish the performance of their products. Of the 50 models of portable chargers that we tested over the past year, 46 had a capacity significantly less than stated. On average the difference was 25%.

For example, the manufacturer indicated that the external battery has a capacity of 10,000 mAh, but in reality it is 7,800 mAh. The difference is due to both the dishonesty of the developers and the improper storage of batteries during transportation and subsequent sale.

Forget to look for the indicator

Some overly economical battery manufacturers do not equip them with charge indicators at all. Which is very bad - just go figure out whether the battery is charged or is almost empty. Therefore, when purchasing, we recommend that you look to see if there is at least some kind of indicator on the case. He could be like this...

...like this...

or even like this:

The fact is that it should be. Otherwise - torment and inconvenience.

Tip 4: consider the self-discharge of portable charging

The actual capacity is also affected by such an indicator as self-discharge.

On average, external batteries with a full charge are discharged by 5% within two weeks. This is worth considering if you do not use Power Bank for a long time. To activate electrolytic reactions, you should charge the device before use.

Keep in mind that the battery capacity will decrease over time. Our measurements show that with active use, a high-quality battery loses its capacity by 15% per year, the cheapest models - 35%.

To monitor the charge level, almost all Power Banks use LED indicators. And some external batteries are equipped with LED displays that show the exact state of charge in percentage.

Tip 5: choose a power bank with multiple USB ports to simultaneously charge your friends’ smartphones

Some models of portable chargers have several USB ports for connecting two, three or even more mobile devices at once. This option is suitable for simultaneous recharging, for example, when you go on a trip with friends. It's comfortable. You can all charge your phones, smartphones and even tablets together.

You often ask us where you can be guaranteed to buy a high-quality external battery cheaply. We cannot give a definite answer. Of course, the reliability of purchasing from a large Russian online store or retail chain is higher, but the prices there are also higher. It is worth remembering that little-known Chinese sellers have a peculiarity: they can deceive. Their external batteries are much cheaper than their branded counterparts; they often indicate a capacity 2 or 3 times higher than the real one. Prices that are too low can be a trap. Although branded Power Banks in such stores can be fakes.

Next, we’ll look at six of the most interesting external batteries for different occasions.

Consider the brand name on the case as a guarantee

The presence of a logo of one or another well-known logo on the case - Samsung, Asus, Huawei, Xiaomi and so on - to a certain extent guarantees the level of quality and reliability. But you need to understand that copying an external battery is much easier than, for example, a laptop or smartphone. And therefore, under the guise of a device from one of the listed brands, they may sell you something that has nothing to do with these brands. Therefore, without taking it as an advertisement, we will give you some advice: it is best to buy batteries from large brands in their online or offline stores. Or at least in large retail chains that carefully monitor what they put on the shelf. Then you definitely won’t run into a fake.

However, incidents sometimes still happen. Not long ago, one fairly large and respected regional retail chain held a promotion: you buy a smartphone of a certain class and receive a Xiaomi “bank” as a gift. In fact, it turned out that the Xiaomi batteries were... fake. And the retail network really didn’t know about this: the authors of the promotion were 100% sure that they were giving away the original.

By the way, we recommend paying special attention to Xiaomi batteries. The company’s batteries are cool, cute and inexpensive, and they are counterfeited much more readily than batteries from other brands. They fake it and then sell it for three pennies, including on AliExpress (see point number one). There are a lot of instructions on the Internet on the topic “how to distinguish an original Xiaomi power bank from a fake.” For example, here is this video instruction. Or this text manual. We recommend reading before purchasing. There are a lot of small nuances.

Universal

The ideal option would be batteries with a capacity of about 10,000 mAh. This is approximately three times more than the battery of a modern smartphone, which means that even taking into account the loss of energy during charging, it will be enough to fully restore the gadget’s charge several times. A high-quality example of such a power bank is the Anker PowerCore 10400 mAh model.

Another option for a high-quality external battery with universal functionality is the Aukey PB-N42 10,000 mAh.

Ports and cables

Devices are connected to the power bank via USB ports using the supplied cables and adapters. Take another look at your devices and ask yourself two questions:

• Firstly, how many devices do you want to charge at the same time ? Ideally, an external battery should have the same number of ports.
• Secondly, what devices do you have ? If you have an iPhone, the power bank should have a Lightning connector; if you have an old iPhone, you will need an Apple 30-pin to USB adapter. To connect other devices to an external battery, you may need adapter cables from USB to microUSB, USB Type-C or a DC-DC cable (for a laptop).

Cables can be supplied with the power bank, but if necessary, they can, of course, be purchased separately. In addition, there are external batteries with attached sets of adapters, including those for peculiar connectors like the same Apple 30-pin.

CHIP recommends: power bank with a set of adapters

Supports fast and wireless charging

If universal options are not your option, then you should pay attention to models with additional functions. For example, a power bank with fast charging support will be able to charge compatible gadgets much faster than usual. If the battery is capable of delivering a consistently high current (about 2A), then even without fast charging support, your gadgets will charge stably and relatively quickly.

Among the ones we recommend is an 8000 mAh Baseus Wireless Charge Power Bank. Its main feature is the presence of Qi wireless charging. That is, to charge a smartphone, you don’t need to connect a wire to it, just put it on an external battery and that’s it. Charging started. In addition to wireless charging with a current of 1A, the device supports a wired USB connection of two compatible devices, while the output current to the USB connectors is 2A.

A good option for iPhone is the Zikko PowerBag 6000 mAh external battery. The main difference from popular Xiaomi external batteries is MFI certification, which means the battery is compatible with all Apple devices. The device supports fast charging - the output current to the USB connectors is 2.4 A. In order to monitor the battery capacity, there are special LED indicators at the end. A nice bonus is that the smartphone is connected to the battery using the included Lightning cable.

How to choose an external battery for a smartphone?

To figure out which battery is best to choose for your smartphone, you need to carefully read the technical characteristics of the product. When purchasing, many device parameters are taken into account. But there are main ones that you need to pay special attention to:

• The declared current strength affects the rate of energy drainage to the donor. It is measured in amperes. If you purchase a battery with a current strength of less than one ampere, it will transmit energy longer than a stationary electrical network.
• Device dimensions and weight. An important criterion when choosing a device, since you have to carry it with you in addition to the main gadget. If it eats up space in your bag or does not fit in your pocket, it will complicate use.
• Suitable types of connectors and their number with the ability to connect several devices at once. All batteries are equipped with standard USB ports, but not all devices have micro-USB, Type-C and Lightning outputs.

With record capacity

If you need a strategic boost of power, check out the HyperJuice 26,000mAh AC Battery Pack. This giant can quickly charge absolutely any device, including a tablet, other portable equipment and even a laptop. There are 2 USB output connectors here. One provides a maximum charge strength of 3A at a voltage of 5W, and the other provides a current of 2.4A. A nice bonus is the ability to provide 220W power to any electrical appliances with a power consumption of up to 100W. You can connect a laptop, a flashlight, and even a blender to this battery.

The HyperJuice AC Battery Pack case is made of aluminum alloy, which perfectly protects the device from external mechanical influences.

10 Best Laptop Batteries

Choosing an external battery: what to look for

Type

Lithium-ion (Li-Ion) and lithium-polymer (Li-Pol) batteries are relevant as of the first half of 2020. Both are durable, highly efficient, and have a large number of recharge cycles, but lithium-polymer batteries are safer, although more expensive than lithium-ion batteries.

Capacity

Perhaps the key parameter of a portable battery. The higher the battery capacity, the more external devices can be charged with its help. Most modern smartphones are equipped with a 3000-5000 mAh battery, for tablets it can be 10,000 mAh, and for laptops it can reach 20,000 mAh or higher. Accordingly, an external battery with a capacity of, for example, 6000 mAh will charge the smartphone once or twice.

The large capacity of an external battery is great, but the weight and dimensions of the gadget increase in proportion to the capacity. A 1500 mAh power bank will look like a pen or a small keychain, but a 25,000 mAh external battery for a laptop can weigh half a kilo and will take up a lot of space.

Voltage

A standard USB port outputs 5 volts. This is what the batteries of most portable devices are designed for, so this is the voltage that most external batteries designed for charging smartphones, players and other pocket devices are characterized by. Power banks that need to charge laptops usually support a higher voltage.

Current strength

The higher the current supported by the external battery, the faster the gadgets connected to it will charge. A current strength of less than 1.5 amperes is not serious.

Supported devices

Most external batteries are designed to charge smartphones, players, smart watches, wireless headphones and other wearable electronics: such batteries cannot handle anything more serious than a tablet. If you want to extend the autonomous life of your laptop, then you need an appropriate power bank: large capacity, high voltage and a suitable connector.

Interfaces

As a rule, external batteries are equipped with one or more USB ports, to which you can connect any cables and charge any gadget: be it an iPhone or a gramophone. In addition, universal batteries designed for charging laptops are usually equipped with a variety of adapters.

Additional functions:

External batteries, like any modern gadgets, compete with each other in the number of additional functions of varying degrees of uselessness. Among the things that can really be useful:

• the ability to charge two (or even three) devices simultaneously;
• the presence of a solar battery - can be useful if you are going on vacation for a few days somewhere in the sun;
• support for fast charging - so as not to wait several hours until the smartphone gains strength and you can free up the scarce connector;
• support for wireless charging - relevant for modern flagship smartphones;
• charge level indication - usually this function is implemented through LEDs on the case or even through a small liquid crystal display. A convenient but not critical option.

Best Medium Capacity Power Banks: 10,000 to 20,000 mAh

This category included chargers from the most famous companies in their niche. Considering this and the fairly high cost, you can expect better performance from them than from less powerful analogues.

Xiaomi Mi Power Bank 10 400

In this category, this model was noted primarily for its faster full recharging compared to other “brothers”; 5.5 hours is enough for it. The reliable aluminum case, which does not break or scratch, also leaves a pleasant impression. Modern Li-Ion batteries, which have virtually no “memory effect,” are not far behind them. They provide a power of 10,400 mAh, which is an average value, but which is quite enough to power iPhones and other smartphones, players, and tablets. But, alas, you won’t be able to use this model at sub-zero temperatures, and it’s not very convenient to carry it with you due to its weight of 250 g. But users have better luck with its design.

Advantages

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

Flaws

• The cable connector quickly becomes loose;
• Takes a long time to charge;
• Heavy weight;
• The edges are sharp.

Xiaomi Mi Power Bank can be called the best external battery among inexpensive models.

You can learn about the impressions of one of the Xiaomi Mi Power Bank users from this video review:

Huawei AP007

A surprisingly decent offer from a Chinese manufacturer, which promises the buyer a capacity of 13,000 mAh. In fact, it does not exceed 12 thousand, but this is not critical. Among the advantages, it should be noted the ability to connect two devices at once and work both at sub-zero temperatures and in hot weather (from -20°C to +50°C). The presence of a charge indicator is also handy, allowing you to control its consumption. There is no need to worry about the safety of the product; it is protected from overheating, short circuit and overload. The advantages are complemented by a metal case, which, however, partially affects the considerable weight of the product - 325 g. The gadget is produced in a pleasant gray color.

Advantages

• Good charge current;
• Stylish design;
• Fits comfortably in the hand;
• Work with two devices simultaneously;
• Overheat protection.

Flaws

• Difficult;
• Slow work;
• The power button sometimes works every other time;
• Does not reach the declared capacity;
• Just one color.
