    Pros: Great unit.. it is small and accurate. It is easy to read and provides at a glance how much power a USB accessory is using.

    Cons: I wish the connector was centered, sometimes you need to use a cable adapter to plug some USB accessories that are bulky. I wish there was away to manually control the voltage and amp display. The unit toggles automatically from one display to another

    Other: It is a good fair price, quite useful and very easy to use

    posted by Cogitosus on 19:05:14 G1T 23/01/2014 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 & currect alternately, it's not possible to monitor both simultaneously, so shourt spikes can be missed, but this is a minor point.

    Other: Very useful gadget to keep in the toolbox, extremely simple to use and good value for money.

    Involvement Level: Expert (understands the inner workings)

    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 should toss in the trash. Incredibly easy to use. It's simple, uncomplicated, does exactly what it's supposed to and nothing more.

    Cons: Because of its form factor, you may need to use this with a USB extension cable.

    Other: This is a must-have diagnostic tool for USB users. I wish I had found this device years ago. Would have helped me clear so much clutter.

    Involvement Level: Expert (understands the inner workings)

    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 or the other

    Other: for less than $6, it's great to have, so if you ever need to troubleshoot whether your PSU is enough for whats hooked up to it or even if you're just curious to how much voltage or current any device draws... definitely a must have for IT folk or tech tinkerers

    posted by marki555 on 15:28:20 G11T 26/11/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 affect the connected device).

    Other: Good device which allows you to see the quality of your charger - you can see the effect of increasing current has on voltage. Ideally the voltage should be always 5.00 V, but usually it will be lower and lower with higher currents.

    Involvement Level: Expert (understands the inner workings)

    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.

    Other: It is a gadget definitely worth having around. Also it's nice to have around a short usb extender for it because it will sometimes not fit some smaller chargers.

    posted by zramix on 19:44:52 G10T 26/10/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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. This can be solved with a male to female USB extension cable, but still the design would be improved it it had a rotate or swivel on the male port.

    Other: Get one if you want to know what's up with your USB ports and charging.

    Involvement Level: Expert (understands the inner workings)

    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.

    Other: A must have tool for technicians

    Involvement Level: Expert (understands the inner workings)

    Pros: Seems to give a reasonably accurate reading on both voltage and current.

    Cons: Does not have the ability for data to pass through it when hooked inline. That is if you hook it to a computer and then hook a USB drive to it you will not be able to use the drive while measuring voltage and current.

    Other: worth having for such a small amount of money. For those times when you aren't sure how much a cheap wall adapter is really charging your phone.

    posted by pakehatribe on 18:53:05 G9T 26/09/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: measures voltage /amps in tenths accurately,example 0.55 =550 milliamps , unit is on a loop 9 seconds display amp-erage, 4 seconds voltage, RED display characters, easy to look at in shaded day/indoors or Night although cant see red characters in direct sunlight.well built

    Cons: well thought out measuring tool, the cant -see-in-direct-sunlight is the compromise to obtain unobtrusive indoor/night time viewing, not a con in my opinion. doesn't appear to allow data to pass when testing a usb hub. still not a con for its intended design/mission. but others intention for this device may differ.

    Other: satisfied, a useful tool to measure usb volts and amps/milliamps.
