I am glad to be able to use this mini USB device that able to measure current, voltage, time and also mAh stands for mili-Ampere-hours and is a unit that measures (electric) power over time [1]. Measurement process is done evening of 29 December 2018.

Start charing with current capacity 1.05 A and voltage 5.05 V.

Finished charging after 2 hours. The device recorded 2,193 mAh is charged to my phone battery.
