  • More than I can every use or know how to read it
Great, the picture does make it look MASSIVE, it's not, probably an 1.25in x 1.5in (not including USB connector sticking out). Works well the resolution on the screen is amazing for the size and has a lot of functions. ONLY issue is buttons are TERRIBLE, not like in feel, but markings. Have to flip the device over to see what they do, couldn't add a nub on one of them to denote main function button. Or print the legend on the face of the device. I mean I kind of get it, they were trying to keep the front semi clean save for the company logo. ... show more

  • It's pretty good but doesn't work with every PD charger.
A few things could be better starting with the $109 price tag. I was expecting a larger screen but it is great very good brightness/clarity. Another issue is when plugging into certain PD chargers it will not display, once a device is plugged in good to go this only becomes a problem if you want to check charge protocols and are potentially putting 20v+ into a device not designed for it (I believe it is not supplying whatever marker is required to turn on PD output?) For around $60-$70 you will get something that I feel is a little better downside is a smaller screen, all the features of this item, still USB-C - USB-C, works with every PD Charger I have without issue (23) ... show more

  • Awesome!
This meter is awesome! It fully supports passing through USB 3.2 Gen 2x2. Gives exactly the information you need and does it FAST. I had asked about Gen 2x2 in a question and the person mentioned the buttons making no sense and not being designed well. I couldn't disagree more. The bottom 2 buttons are Up/Down. The top button is Back. That leaves one last for Enter. Super easy! This meter brings a whole new level of diag for cables and power supplies. ... show more

  • Sometimes a little flaky--More than you need or want?
ChargerLAB stuff can offer a lot of options and the ability to see what USB 3 protocols are supported. At the same time, it always seems to be just a bit unpolished and semi-finished. I find this both useful and frustrating to use. If you are patient and learn the operation of this tester you will find it useful. If you want to just get a quick reading of current and voltage, you would do well to pick another device. You might find this does more than you want for a price higher than can be justified. ... show more

  • One of the best usb analyzers out there
I am very happy with this purchase, it really does tell you what all of your chargers do i like how it helps analyzes cables as well, I would suggest reading their website to see all of the full capabilities, its expensive but for a very good reason. does a lot

  • The KM003C blows the Fnirsi FNB58 out of the water.
The protocol detection works way better than the fnb58, the display is far easier to read, and the build quality is noticeably better. Both my fnirsi’s can with bent usb a plugs. They both do rough the same thing overall, this just does it better, which for double the price it should. Worth it if you want the best usb meter currently available. ... show more
