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
produto bom, falta melhor acabamento botão ficar travando quando precionado, de resto está otimo
Very good product. Display is bright and easy to read. very helpful for monitoring power consumption and current draw. There is a button to reset the timer and mAh counter. Works perfectly!
