Power Banks – Product Review and comparison in 2021
It is very frustrating and annoying to leave your battery on your phone, tablet or laptop when you need it most. In order not to go through such unpleasant moments, it is best to always have a Power Bank (external battery) close by, which will charge your device with energy, so that you can use it until you have access to a socket for recharging. Wouldn’t a list containing some of the most popular products of this kind on the market help you? You will find it below. At the forefront is theASUS ZenPower , a 10,050 mAh battery that will help charge a phone 2-3 times, if the device’s battery is about 3,000 mAh. It is universal, so it will fit a lot of phone models and not only, the connectivity being done via micro-USB. The charging time of this model is 6 hours, the output amperage is 2 A and the voltage is 5 V. It comes with key features like PowerSafe and battery level indicator. The dimensions are 90.5 x 59 x 22 mm and the weight is 215 grams. It is black and has an affordable purchase price. If you want a model with an even larger capacity, see ADATA P20000D .
It is an external battery, with a fairly large capacity of 10,050 mAh, to be able to power your phone 2-3 times (if it has a 3000-4000 mAh battery) and has an output amperage of 2 A, to be able to use the smartphone while it is connected, without affecting the charging time.
This Power Bank allows the power of a single device, as it has a single USB input, which can be unpleasant for some people.
Buy this external battery if you want to be able to charge your phone or tablet several times, because it has a capacity of 10,050 mAh.
We recommend this Power Bank primarily due to its large capacity of 20,000 mAh, which makes it possible to charge a 4000 mAh phone even 4-5 times. Then, it offers the possibility to connect at the same time two devices with USB interface, but also to use a flashlight.
Due to its dimensions (163 x 80.6 x 23.3 mm) and weight (450 grams) we cannot say that it is a portable model.
This Power Bank is a suitable choice for people who want a quality product, with a large capacity and a decent price.
It has a very large capacity of 20,000 mAh, which will lead to multiple power cycles (4-5), depending on the size of the battery that the device you have. It is also equipped with the Fast Charge function, to allow an even faster charging, and offers you the possibility to power two gadgets at the same time.
Very important information about this product, such as the time required to charge it with energy, is missing from the purchase site.
It is our recommendation due to the large capacity, the Fast Charge function and the rich interface, which allows you to power two devices simultaneously.
