Product Description

Function Operation
Up/Enter/Return key: Short press is to turn up the page or adjust the number; long press is to enter or return and other functions. (Warm tips: when you are on the first two pages, long press this key to turn black and white)
Down/Reset/Confirm key: Short press is to turn down the page or adjust the number; long press on different pages respectively is to reset the power capacity, pause the curve, confirm, reset the no-load current and other functions. (Warm tips: quickly press this key five times to lock and unlock the screen display direction)
Question Answer
Q1: Why does the product not display when the product is plugged into the charger alone?
A1: The Type-C port of most chargers has no voltage output by default. At this time, the product has no power supply and no display. Only when the load protocol is detected will the charger have voltage output and the product will display at this time.
Q2: Why can't the test meter measure 10A or 120W when my product charger is marked with 10A or 120W?
A2: The value tested by this product is the real-time charging parameter during the charging process. The parameter marked on the charger is the maximum power parameter of the product, and it does not output such a large parameter at any time.
Q3: Why does the output occasionally display a current of 0.01-0.02A when there is no load connected?
A3: This product uses bidirectional current detection. It is normal to have a very small no-load current, but it can also be cleared by quickly pressing the function key in the current clearing interface.

    super useful, seems responsive
    5 out of 5 stars
    super useful, seems responsive
    Things I like: > Two buttons for control - one changes the way the information is displayed and another one rotates the data 90 degrees each time you press it > Screen as black/white and color modes. Both are super bright and look nice > Works just like i'd hope - responsive, no lag or anything Things to know: > It's only for usb-c devices. I presume it would work if you have a usbc to a adapter but I don't have one and did not test this. Things I dont like: >none! This thing is awesome. I'm somewhat a collector of various charging stations and adapters (i have a problem) and I always wanted one of these to validate the power output. I currently use a battery pack that has a rudimentary voltage/amperage display but this would be more useful and has higher precision (though I can't verify the precision).

      The media could not be loaded.
      When I have a tool or instrument I like when it’s easy to use without a lot of complicated screens and pressing buttons, and all kinds of multifunction type of things. But this meter you simply just plug it in and that’s it. There are 2 buttons, however, I find that the instructions aren’t quite clear and as always, you need to do your own poking around to find out in your mind how these things work. But most of all it gives you the basic data voltage amperage, wattage, and watts hours. It will show you the accumulative watt hours. The screen auto rotates or what you call gravity screen. Is small and compact and completely enclosed, not like the other ones that look like they have two circuitboard screwed together like a sandwich. It seems to do PD charging. I am learning more about this in their protocols. also with the other USB meters there’s an adapter that you have to plug in for the C type protocol. And it seems like they won’t read anything other than PD‘s type C.It’s looks like they’re not quite made for the other types of USB other than type A. They also have a Data out for Jack. This one does not. For this particular meter it’s visual information that you can see real time. If you look closely at the very tiny bottom banner, it shows how much time it took for the particular charging event as well as peak, wattage and voltage. A very interesting little meter. I recommend this USB meter.

      Out of the box it was about +.4V off but once calibrated it's spot on. Easy to do, plug in a charger that puts out exactly 5 volts and go to the language/calibration screen, navigate to the "calibrate" push and hold the down button until it says "OK" While you are calibrating do not have it connected to anything other than the charger. No load.

      Reviewed in the United States on March 19, 2025
      Color: Dark GrayVerified Purchase
      This is ONLY an in-line tester, meaning if you just plug this device into a USB outlet it does nothing. This is an in-line only tester meaning you have to connect it between the power outlet and the device being charged.
      If you just want to test a USB power source, this is not the device for you.

      The amount of info provided by this tiny device is pretty impressive. With this tool, you can test any of your charging adapters, cables, charging ports, or USB battery power supplies to determine if they are putting out the voltage that they claim. Great little tool for the electronics tool box.
