  2. 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 🙂

  3. 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.
