Kavalan USB Type-C Power Meter Monitor, OLED Multimeter Charging Tester for V & A & Watts, Bi-Direction Indicator with Display Flip Button

Neat little gadget, works great and easy to use.

This thing just works. It displays the load flow direction via an arrow and the current values of the voltage, current, and wattage. I haven't had any problems with this thing. It's simple and it works. Worth the money.

I bought this to confirm various devices and accessories.It is very easy to use (love the screen orientation flip) and has seemed to validate everything so far.I have more things to test, but even after just a handful of uses, I have noticed one small defect. When in operation, it produces a small but noticeable high pitch buzz, it is so faint you almost cannot tell where its coming from.This is audible to my ~30 year old ears when closer than a body length away. Your hearing and mileage may vary. Perhaps I have a bad unit, but it's not bad enough to go through exchange process.

I bought this to test a new 3rd party power supply for my MacBook Pro, and it worked as expected. I've since given it to one of the engineers of my company to use on testing new products and he is in love with it. We make external SSD enclosures and testing voltage prior to this has been stripping down USB-C cables and using a volt meter. This has simplified the process and gives us the same results!

I was lucky enough to pick this up for $10 (sale I guess?)There are zero USB C power meters near that price at the time of writing this review.Works as advertised, and I'm quite happy with it!!!I only wish it were as fancy as my "USB Safety Tester" which shows time elapsed and total power and current consumed. Can't complain for the price though!

Larger font, watt rating, easy to switch from upside down make this superior to others I've tried. One thing to watch for is that the the two sides need to both the same "polarity" (don't know if its actually polarity, but it acts that way. If the display doesn't light up, unplug one side, turn it over and plug back in.

Accurately has read everything with fairly fast update/refresh for changes, shows me what combos of charger/cable/device are best not all combos are created equally when you have PD Charger and Device. I have one small gripe the thickness of the case is too fat close to the body, so i had to grind down the case 1mm on both sides of the USB to plug into my phone with a case on, and the only thing I think would be nice is logging and dump, so you can track the IB V/A and W and correlate with device battery voltage logs.

the usb c connector is too easy to break off. You have to support the weight of the cord or you will damage this tool.
