    s

    Multiple Port

    there is a USB-C inpot and Micro USB port, you can use this 2 port to test the resistance of a cable, for testing current, jus use USB-A in and USB-A out to check the voltage and current

    Protection Film

    Our USB meter has protection film, maybe it fits the panel so well that you can not see it, but it does exist!

    Work together with USB Load HD35

    For our USB meter, it can work together with our USB load HD35, you can use HD35 to use certain voltage and current to discharge the charger/power bank, and view data on the USB meter to check the performance of charger/power bank, you can search "HD35" in our store to order it
