The USB Power Current/Voltage Tester from Brando lets you easily measure USB power and device operating current/voltage. Just plug the small USB adapter between the device and your computer or AC outlet and the built-in display shows current and voltage. It will work with smartphones, tablets or any devices with a USB charging port. It is able to read voltages from 3.5 to 7V and current from 0 to 3A. The USB Power Current/Voltage Tester is priced at $10 and is available from Brando.

    Oh, I just bought the same (from a cheaper shop http://www.buyincoins.com/item/34684.html )
    I’m playing with it for 2 days.
    It helps me to know when my gopro 2 camera is fully charged (my camera has a slight defect with the battery and is unable to tell when it’s full).

    Thanks Fabien!!!!!!!!!!!
    I don’t know why, but this website always puts up items from Brando, which are cool etc, but always over-priced…..
    I wasn’t aware\thinking that such product existed- now there seems to be a way to measure all the generic USB wall cahrgers that can be bought in Chinese websites for cheap etc..
    Cheers :)

    This doesn’t actually measure the USB wall charger (well, it’ll tell you if it’s capable of putting out what it says it puts out, and with a standard kill-a-watt you’ll be able to work out efficiency.) This is designed to measure the *device* that you are charging.
