    5.0 out of 5 stars indispensable to check charging power

    Comes in very handy when charging my phone or earbuds or watch on my desk stand. Confirms the exact charging rate. The button in back to change display is a bit small for my fat fingers....I use a stylus to click the button. Otherwise, nicely priced and easy to use with integrated USB C male / female connectors

    4.0 out of 5 stars Nice Little Tester
    Reviewed in the United States on January 19, 2025
    I needed a USB-C tester as that is where connections are going. Initial testing the unit appears to work as it should. Three different display options are nice, especially the graphing mode. Though a bit hard to read due to the small font (and my aging eyes) on the main screen, it provides a lot of data. For the price, I feel it's a good value.

    This usb-c meter worked great for a month then it stopped working suddenly. I’ve tried different sources and cables but to only work when plugged into a usb-a port. It will not power on when plugged into a usb-c port.

    5.0 out of 5 stars Works really well; nice and compact
    Reviewed in the United States on July 3, 2024
    I used this throughout the day while charging miscellaneous devices and I have no complaints. It's quite a lot like the first Kowsi USB meter I bought except it appears to be upgraded in most ways. It's a bit smaller with a nicer case and button. It just has a male USB C connector sticking out one side rather than on the end of a short cable.

    The display also seems upgraded with additional information, and the convenient ability to double tap the button to flip the display. It even has a little chart though I'm not sure how useful that is.

    I'd easily recommend this if you're in need of a way to keep track of USB-C charging power and device battery capacity.

    3.0 out of 5 stars Usb-c only; small display
    Reviewed in the United States on December 20, 2024
    The unit has a colorful and nicely quick update rate, and, shows a lot of information. IF, that is, you can read it; the display is too tiny for my old eyes.
    Al8, it would be more useful if there was usb-a input.
    Overall, it works as advertised if you are ok with usb-c for input and output.

    4.0 out of 5 stars Handy USB-C power monitor
    Reviewed in the United States on July 5, 2024
    This little meter makes it easy to verify that my USB-C chargers are working properly. I like being able to watch my phone's charging in real time, including any changes in power demand. The meter passively monitors the charging process, so it doesn't interfere with USB-PD/PPS/etc. I wish that the unit could display information about the protocol in use, but I can get by with the basic power info that it does show.

    The single-button interface is simple enough, but it can be a little quirky. Sometimes a short-press on the graph screen will change the time scale, other times it needs a long-press (as documented in the instructions). Sometimes the graph resets when you change the time scale, sometimes not, and I haven't figured out why. It's not a big deal, but I do end up clicking the button more than expected.

    Physically, the meter is nicely built, and the screen is tiny but clear. The design isn't perfect, however, as the male USB-C plug can have trouble seating into a recessed port. For example, I must take my phone out of its case before I can plug in this meter. It would be better if the plug extended out a little further, or if the meter's housing was tapered at the male end.
