One of those USB chargers - 4 ports - 2 are 1amp and 2 are 2.1amp - how do i test which is which?
I thought about taking a usb cable - cutting the end off - and using the bare wires against a multimeter - but i will need a multimeter which measures amps?
will one of those digital ones from builders for R150 odd work?
