    I wish the connector was centered, sometimes you need to use a cable adapter to plug some USB accessories that are bulky. I wis...

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    A simple layout with clear display of USB port volyage and current consumption. Could not be easier to use,
    Cons:
    The right-angled design may not fit a small number of USB ports. Because the device uses one set of digits to display voltage &...

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    You may have USB power supplies that produce <5 volts. Or some that fail to deliver the amperage they're rated for. I'm not 100% sure if the results this device produces are accurate, but it certainly has helped me isolate which of the many USB adaptors I...
    Cons:
    Because of its form factor, you may need to use this with a USB extension cable.

    Pros:
    Small, compact, accurate, easy to read display.
    Cons:
    Wouldn't mind shorter times between switching between current and voltage. Or maybe a button/switch so i can manually see one ...

    Good little tool

    posted by marki555 on 11/26/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    You can measure both voltage and current without any special connections. The display is good (4x red 7-segment led digits) and alternates between volts and amperes (current).
    Cons:
    Under full load (1.05 A) seems to periodically lose the power, so keeps resetting and displaying only the voltage (but does not...

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    This is one useful little gadget. It's perfect when you are using several devices like tablets, phones, portable batteries and chargers. You can see without any hassle what voltage the USB port has, and the current draw of the device.
    Cons:
    The only con is that it will not let data connections pass through it.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    This is a very handy device if you have anything with a USB Port on it. This will show you both current and voltage. It can be incredibly useful to determine what charging issues are on USB devices.
    Cons:
    I wish the usb port rotated, sometimes it will wind up with the display facing down or away from you and can be hard to read. T...

    Very interesting

    posted by Nafai on 10/16/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    It's a seamless way to diagnose, not only the voltage (which is really easy) but also the current consumed by any USB device. Yo can diagnose faulty chargers and problems with charge process, such as slow charging or not charging at all.
    Cons:
    Depends on USB orientation, mine gets faced down in one of my devices.
