Ever felt that one USB charger / cable charges your device really fast and the other doesn't? Now, you can test this with Ampere. Not all devices are supported because there are devices that lack an appropriate metering chip (or interface) and cannot be supported at all. Read the list of unsupported phones at the end of the description. The app is not intended to be mA accurate. It is only good to evaluate which charger / USB cable combination works best for you on the same device. Launch the application and wait approx. 10 seconds ("measuring" is on the screen). After this time, the charge or discharge current will be displayed.
