Reviewed in the United States on 2 August 2018
If you’re a Maker or even if you you’re like me and just love working with electronics, this is a great tool/toy. Need to know how much current your Arduino or a peripheral draws? Just plug it into this. Want to know if a battery pack puts out the mAh that it claims? Plug it into this and a load. I thought this would be more of a toy but this little device really has a lot to offer. Computer and Android apps (via Bluetooth) to control it and view everything on one screen. That’s good for old farts like me. It’s easier to see the data on a bigger screen. I really like this! My daughter and I do a lot of experimenting with Arduino, Raspberry Pi and just electronics in general. This will go a long way towards making us better at what we do and making what we do more efficient.

Phenomenal features for the price and money! Some notes to get you up and running fast: For English, press and hold the button while powering up, to switch to English, then scroll. Two pair with the android app, it will ask for a pin, which is "1234". The graph displays of voltage and current, is very helpful for troubleshooting USB electronics. I definitely agree with all of the positive features mentioned in the other reviews! Excellent product!

The item does absolutely every single thing it claims to. It may be a bit daunting if you haven't yet looked into things, being greeted with another language and all. But so long as you're on the ball, you'll have an easy enough time with it. The software is a bit, meh... Not in functionality, it does what it should. Presentation could be better, with digits running out on either side of certain margins, but it's no big deal. The bigger thing is getting the software at all, I found a link in someone else review, followed that back to the wrong product, then browsed the directories of the mediafire tree until I found what I needed... and even then, it was a bit vague as far as knowing where I should be, what I should be using, etc. But it worked out. This along with the load pictured in the one image, are a fantastic pairing for troubleshooting purposes. The meter can do quite a bit on it's own, but bringing in a tune-able load is an entire other ball of tech diagnosing abilities brought forth. Thank you very much for taking the time to make an actual worth while product, it is worth every penny.

Reviewed in the United States on 16 September 2019
If you are trying to figure out what your USB-C devices are drawing , this is so far the best usb-c power meter I have used. Capable of delivering accurate PD readings, doing so in BOTH directions (charger end going out through the device, or device connected to host usb-c port to see what it is drawing), it is great.

It also draws its power from the line. This means it will use some of the current that can skew readings, but it is almost insignificant for the common person who just wants to see numbers to the left of the decimal anyways. I have not gotten very deep into calculating real world losses because it seems pretty efficient.

It is what it looks like, some plastic pieces screwed into the mainboard and a plastic support structure holding it all together with some brass inserts. I have had one of the screws come loose once, just gotta check em or loctite them once in awhile.
It comes in a nice case that does not add too much to its size. You should keep it in this anytime you are taking this somewhere with you. I would prefer they found a way to add a cap or something to it in the future. The unit itself is rugged enough but the usb-c plug protruding could get tweaked pretty easily.

As I have moved over to testing more multi-port usb-c equipment I have expanded to a few of these and have not had any problems with any of them. If that changes I will update this review promptly.

If you found my review helpful - thank you.
If you did not, please hit me up in the comments so we can change that.

Thanks for reading,
-Chris
