Starts with the Built Quality, overall built quality is good for this power bank, the surface has tiny dots(Perforated Exterior) like patters for better grip, scratch-resistant, and comfortable to hold. The material used is environment-friendly PC+ABS. The whole body of power bank looks bulky and its overall size is on a bigger side, so if you want a compact size power bank this is not for you. Here we get only white color options which may become a problem for some users because white gets dirty fast, However, we do get the black color option in 10,000 mAh of it.

Now let talk about the important thing, the performance, this power bank comes with 20,000 mAh battery capacity, and out of 20,000, only 13,000 mAh is usable means you can charge around 4 times MiA1, 7 times iPhone 7 and 3 times Redmi note 5 pros. it has 2 x USB port for output which supports quick charge 3.0 but at a time only one port can be used to charge fast to only one device connected to power bank, if you connect on both the port neither of the port will charge fast. this power bank also provides the facility to charge the power bank and the smartphone connected to the power bank, charge simultaneously (also called as pass-through charging).

According to Xiaomi, it offers high-quality circuit boards which improve the safety of the device and have 9-layers of circuit protection which enhance the safety/efficiency for both charge and discharge like – temperature protection, short circuit protection, reset protection, input overvoltage protection, incorrect insertion protection, output over current protection, output over-voltage protection, overcharge and over-discharge protection, Hardware-level short circuit protection. there is also a low power charging mode for the low power devices like the Mi Band and Mi Bluetooth headset, you just have to double press the power bank button for enabling low power mode.

Overall, the performance seems to be good and this power bank by xiaomi is value for money. I have done my testing thoroughly with multiple smartphones before writing a single letter about this power bank.
