This thing is great. It solves all of the mysteries of slow phone and tablet charging.Just plug it in and select the display you want to use and it will show you the real facts on power delivery.I just got it but it's already shown me that nearly every USB C cable I've purchased doesn't deliver the promised amount of power to my phones...so back they go. It also displayed the performance of several chargers that I though were doing their job...3 out of 4 weren't.Finally, I can see the truth with my own eyes, and it only takes 5 seconds.

Kinda hard to switch through everything, it is kinda confusing but it works as it should. It comes with instructions which should help but I don't like reading. I'm a learn as you do/use it, person. Over all, I like it. (:

Love seeing how much juice is actually flowing between my chargers and devices!!! No more guessing and this meter does both USB C and Regular USB A 2.0.

Works great. Can be a little hard to read but don't have to worry about cables adding resistance to the measurements.

This is great to test the power of the many USB charging options in my house and car to find the most power for Ipad charging.

Really like being able to verify that my devices and cables are working to max potential. Not for everyone but if you have a lot of devices to keep up with this will save you time and money by pin pointing problems

Takes all the guesswork out of what charges what the fastest. Also helps spot fake/scam chargers, especially in this new USB-C PD world.

You never know if a cable is bad or a power adapter has taken a dump. It also allows you to verify the claimed output of a power adapter. Sometimes you can be surprised.
