    Seems accurate
    Useful for detecting broken chargers. Found one in my house that gave out 6 volts, slowly destroying my tablet's battery. RIP.
    Shows both amps and volts.
    It's solid! Seems cheap at first, but it's really sturdy and it's also easy to read.
    Worth the money, I'd say.
    Nothing, really.

    Good tester
    I bought this to test my chargers. Was surprised to see that one of them supports some QuickCharge.

    - Easy to use
    - Bright display

    - The plastic body seems to be weak

    Fantastic usb voltage tester / Fantastico medidor de voltaje usb
    Very ease to use and very clear led display to see the volts and amperes used by a charger or battery. The display changes volts measure to ampere automatically.

    Muy facil de usar y con digitos led claros para ver los voltios y amperios usados por un cargador o bateria usb. El display cambia automaticamente de voltios a amperios.
    None. I really like this product.
    Ninguno, me gusta mucho este producto.

    Works like a charm
    Does what it say, I'm not 100% sure about how accurate is it.
    but it's not a big deal
    this will give you a good approximation of how much Voltage and Amp your device gets.

    And for this price, what more do you need?
