    Incredibly useful little gadget! I use it to see if I've been scammed on battery capacities and to test if my devices are charging properly. Using it I also discovered that lots of USB wall chargers lie about the amps they output on their packaging. You can also just plug it into a power-bank to see if it has any juice left.

    good little unit , gives enough information, voltage , current , mAh , power , temp (internal) which is all you need for a quick tester

    It works very well, keeps the history even turned off and has a button on the side to restart the counters.
