Mi Power Bank: a good partner for batteries

In full 2015 we still need to deal with batteries that don't last a whole day. And if you need to demand more from your smartphone, it's a good idea to have a portable charger with you. THE Xiaomi launched together with the redmi 2 a We Power Bank, I received the accessory with the device and I was able to use it in the last few weeks.

O portable charger it has a textured aluminum body – resistant to water and corrosion – and withstands a pressure of up to 50 kg; there are two inputs, a microUSB and a traditional USB. It uses lithium cells from LG and Samsung, and according to the company, it has nine protection technologies to avoid voltage spikes and overload, control the temperature, and protect the battery in case of short circuit.

A We Power Bank has an internal battery 10400 mAh, which are capable of doing 3,4 full charges on the Redmi 2 or 4,5 full charges on the iPhone 5s. These numbers are provided by the manufacturer; in practical use, the efficiency is slightly lower. Even more so if you recharge with your cell phone on or in constant use.

The high recharge capacity brings a negative point: the weight. It's an accessory compact (90,5 x 77 x 21,6 mm), but weighs 254 grams. Not the most comfortable device to take on the pants pocket, for example. However, it won't take up much space in a purse or backpack.

Indispensable accessory on long journeys, the We Power Bank can be acquired by R$ 99,00 on Xiaomi's official website.
