Essential tool for phone diagnosis. Plug into a usb charger and then plug whatever device into the other end and it will tell you the voltage and current draw of the device. This can tell you whether phone is charging, if it has dead battery or motherboard or if there's a short circuit.
You can also use to measure true battery capacity by draining battery then measuring how much per it takes to charge the battery.
