The best power banks are extremely useful devices that you should always have with you. This small gadget will fit in any woman’s purse or backpack, and in an emergency it will relieve the stress of a discharged smartphone. People who use power banks recommend the Xiaomi 3 PRO PLM07ZM with a capacity of 20,000 mAh, which is enough to complete several charging cycles. The power bank is equipped with 3 different USB ports that allow you to connect different types of chargers. The power bank is made of high-quality materials, which directly affects the durability of the device.
Another recommended model is Samsung P1100 EB-P1100CSEGWW . This small external battery is very light and thin. The technology used allows you to charge two devices simultaneously, as well as connect equipment with the Adaptive Fast Charging function.
The best power banks of 2021-2022 - what to look for?
When choosing a power bank, several factors are decisive. The first is portability. Some of the devices we review are small and light enough to slip into your pocket. So pay close attention to their weight and avoid bulky models if you plan to carry a power bank with you every day and not just occasionally. In the rating, we focused on lightweight models intended for everyday use.
The power output indicator is also important when choosing a device of this type, which shows how quickly the power bank will charge devices. In most cases, this will be an indicator with an output of 1 A (5 V), 2 A (10 V), and often even 2.5 A (12.5 V). The first one was designed for smartphones, while the other two were designed for tablets and phones that support fast charging. By the way, it’s also worth paying attention to the inputs, because the use of USB 3.0 and USB type C can speed up charging of the device compared to USB 2.0.
The best power banks usually have an auto-on/off feature, although some only support auto-on while others have neither of these options. Auto-on allows devices to start charging our equipment as soon as it is plugged in, and the auto-off option allows us to turn off power supplies after charging is complete, saving energy. However, devices that do not have this feature will have a small switch somewhere on the body. It is also commonly used to illuminate an LED flashlight (if a given power supply has one) or to check the remaining energy.
In most cases, you will find a series of LEDs that indicate how much power is left. This is a good solution for power banks with a smaller capacity, but for models with a larger capacity this option is not entirely suitable. So it's good to look for equipment with an LCD display that can give out the exact amount of remaining energy - so as not to experience an unpleasant surprise in a crisis situation.
A frequently used accessory for power banks is the already mentioned built-in LED flashlight. It can be useful, for example, when traveling or on particularly busy days, but you need to remember that such equipment must be relatively comfortable and have an ergonomic design, otherwise it is unlikely that you will use it as a flashlight.

External batteries - large power banks from Xiaomi, Rombica, Buro and others
Before reviewing various power banks of different capacities for smartphones and tablets, watches, fitness bracelets and other electronics, let’s take a little look at what exactly you need to pay attention to when buying external batteries.
Housing materials
Power banks are made of various materials, namely metal (aluminum) and plastic. There are also differences in the form factor: there are cubes, tubes, rectangular or stylized. Since power banks are primarily necessary for use anytime and anywhere, the purchased external battery should be as convenient and compact as possible, easily fitting into the same jeans or jacket pockets. It is also better to give preference to metal options, since plastic batteries may be a few grams lighter, but they are much inferior in reliability. With active use, the plastic coating can crack, quickly fray, or break, which cannot be said about aluminum.
The right Power Bank with the optimal current
The current supplied by the power bank greatly affects the charging speed of a smartphone/tablet or any other gadget. The lower the current and/or voltage, the longer it will take for connected devices to charge. For inexpensive entry-level gadgets, it is best to use external batteries with a current of 5V/1A, for mid-price ones at least 5V/2A, and so on in increasing order. If you have a flagship, then you need to find out whether it supports fast charging from Qualcomm, Mediatek, Samsung, etc., and then focus on the current parameters required for the device and select the appropriate power bank. After all, we can’t always charge our smartphone or other device smoothly; sometimes we need fast charging on the go in a limited period of time.
Compatibility of power banks and gadgets
If you only have a smartphone or tablet, then an external battery with one USB port will be enough to charge them. Otherwise, you should look at power bank options with two or more ports so that you can charge several devices at the same time. And it’s best to choose the latter option, although as a last resort you can always buy a USB hub.
Functionality of external batteries
The main task of a power bank is to transfer the accumulated energy to the device that needs it. However, in order to stand out from competitors, many manufacturers go further, offering flashlights built into external batteries, digital displays to display the percentage of remaining charge, etc. There will be no advice here - take what you like.
Buying guide - which power bank to buy?
Buying a power bank is a good solution for people who spend most of the day outside the home and do not have constant access to the power grid. Many people who study or work outside the office are willing to use an alternative that will allow them to charge their smartphone, tablet or car navigation if necessary.
This little gadget has the same battery as a mobile phone. The charging method is the same as with a smartphone. But portable energy storage devices are much more practical. The 10,000mAh+ model performs multiple charge cycles, meaning it can be used multiple times. This is a very good option for people who don't have access to an outlet or who go on a long trip without being able to plug their smartphone into an outlet.
What electronic devices can be charged using a power bank?
Power banks are devices equipped with at least two USB ports. The first is standard, for charging a spare battery, the other is for transferring energy to other electronic devices. Most people buy power banks to charge their smartphones and tablets, but this little device can also be used to power car navigation devices, music players, game consoles, digital cameras and smartwatches. The power bank includes a micro USB cable that allows you to charge the above-mentioned devices. An induction battery for charging devices equipped with this technology is also increasingly available for purchase.
Which power bank to choose?
When considering which power bank is best, it is worth determining what capacity will be optimal for a given user. People who frequently charge their phones and tablets away from home should choose a device with a high capacity. High-quality equipment should allow you to connect your smartphone at least twice and fully charge the battery.
According to reviews, the best power bank has a capacity of 10,000 mAh. This is a safe value that allows multiple charging cycles. The number of recharges performed depends on the recipient's battery capacity. If the smartphone has a 4,500 mAh lithium-ion battery, the 50,000 mAh power supply can handle up to ten charging cycles. New phones with larger displays have much larger batteries than models released a few years ago. Mainly for this reason, mobile chargers with a capacity of less than 4000 mAh are not so readily chosen by consumers. Today, most users decide to buy a model with an energy storage from 10,000 mAh (for example, an 80,000 mAh power supply) to 30,000 mAh.
What additional functions should a power bank have?
When deciding to buy a power bank, you should pay attention not only to the capacity of the device. In many emergency situations, additional features such as an LED flashlight or solar charger can be very useful. The largest power bank with a capacity of more than 10,000 mAh is often equipped with an LED flashlight that consumes little energy. LED light is intense, so it can be useful in any situation.
A feature that users appreciate is solar charging, which is useful while hiking or camping. The panel, exposed to sunlight, allows you to charge the power bank without connecting to the mains. This is a very practical and convenient solution that makes the device completely mobile. Other features that users prefer include a built-in power cord or a durable handle. A power cable that is permanently connected to the device, or a power supply with a built-in cable, is a good solution for forgetful people. Thanks to this solution, the user does not have to forget to put the cable in his bag or luggage. Smaller power supplies often have an eyelet for attaching to a key or lanyard. who doesn't like looking for a device in a backpack.
Power banks at good prices
Buying a power bank is a cost that depends on the capacity and additional functions of the device. The cheapest models can be purchased for 300-700 rubles. Of course, a power bank of up to 1000 rubles is enough for no more than one charging cycle, which may not be enough for demanding users. Models with a larger capacity of 10,000 mAh cost from 1,000 to 7,500 rubles, depending on the manufacturer. When deciding to purchase a suitable device, it is also worth considering the quality of workmanship and additional functions. All these elements add up to the price of a quality branded product. Of course, a power bank for iPhone produced by this company will be more expensive than non-branded models.
How to properly care for a power bank?
When you know how to choose a power bank, it's time to talk about guarantees of its durability. The power bank ratings represent truly reliable solutions, but it is up to the user whether the solutions offered at this level will last longer.
Keep in mind that the best way to extend battery life is to fully charge it . “Refilling” by a few or ten percent is not the best solution. In the same way, it was discharged to zero. This also does not have the best effect on the quality of the battery.
It's also worth remembering - when you're not using the device for a long time, make sure it's charged. Maintaining power, even at a few tens of percent, is important, and be aware of the automatic loss of power from power supplies that will drain them completely within a few weeks.
For safety reasons, you shouldn’t overheat power banks either . These are electrical devices, after all—and unless we're talking about solar models—excessive temperatures are not good for battery life.
