USB C Tester with Cable

Perfect for testing output and throughout from your usb power source to your device. Smaller than I expected, but the display is bright and crisp.

Handy to see what is going on with chargers and laptops/ tablets

Gets the job done with accurate voltage and current readings, but the build quality feels a bit cheap. It’s functional for basic testing needs, but don’t expect a premium experience. A decent option for occasional use.

Excellent but of kit works really well.

I'm a keen experimenter with overclocking and added peripherals so was looking for a USB test meter to put in line with the PSU feeding my Raspberry Pi5. This has been absolutely perfect for the job.My only concern when ordering was the tiny font size used by the display, but it's absolutely pin sharp with an excellent contrast ratio making the small characters very easy to read.I believe I bought this around 5 months ago, and it's been in 24/7 use since the day it arrived without a single hiccup, and there are no signs of any display burn-in.Highly recommended.

When heading out for a multi-day backcountry hike these days there's rechargeable lights, phones/gps etc. to consider.So portable solar becomes a thing - with quoted outputs ranging from almost plausible to hilarious.There's no magic here. Bigger panels receive more sun & produce more power but the circuitry also (seems) to be a thing.If you've ended up dissatisfied with a panel and bought another (and another, or more!) how do you know what they are doing for your lamp etc?So, for me at least, in steps this device. Jack in your phone, rechargeable lamp etc. to this and the other end goes into your panel - under cloudy, sunny conditions etc you then get real data about how your panel interacts with your kit and the watts it's actually delivering.Invaluable. Recommended.

I had to buy one of these as my original tester was USB A in and out .. this enabled me to test a usb-c battery pack output.Using some A-C and C-A adapter I was able to compare accuracy with my well used/loved USB device .. showed exactly same results.

Wanted something to check the output of my devices and this one did the trick, small display but perfectly readable and worked as it said.
