## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice and Simple
*by Z***L on July 12, 2023*

What's different about this one (the USB-A Tester and Meter), is that it has the tester built in. I haven't really come across any USB power meters that have that feature. Either that or I have, and they were just too complex for me to realize that they did. What I would really like to see though, is something that's just like the power meter that has a USB-A and a USB-C output and input, and that also has a tester like this one does. As far as basic testing of what devices are charging at though, this tester and power meter works quite well, in my opinion.

### ⭐⭐⭐⭐⭐ Good pass / fail tester.
*by S***Y on August 21, 2022*

I bought this for testing USB ports in campers while working as an RV Technician. 910Beside the data display screen there is the test screen which has 4 load levels to choose from.I have had a charge port ‘fail’, and it dimmed the bedroom lights too which indicated a problem. Very rare, but you don’t want to sell an $80k 5th wheel hauler that has a plug that won’t charge your phone!I’ve only played around with the pass thru feature so far, bought it for testing USB ports, which it does great.This isn’t for everyone, definitely a techie gadget. I only wish it had its own power so that I didn’t have to wait for it to ‘boot’ before testing. Some RVs have several ports throughout.I would buy again but I shouldn’t ever have to. It’s of good Klein quality. I like it.

### ⭐⭐⭐⭐⭐ Very good product
