    • Does what I want
It's hard to rate something that you don't use constantly, but it works when I need it. Accuracy? No clue since it's the only one I have and I don't have anything to check it against. It's easy to read, easy to use. It appears well made and shows me all of the information I want and I would purchase again. ... show more

    • Very nice little testing device
The display is excellent. USB-C in either direction and allows all kinds of testing as long as you have a few USB-A to USB-C adapters (both male to female and female to male). The data seems accurate given that I know what kind of power I should see from/to a certain device. Although I am still confused by the calibration "feature" of this. It seems odd to need to do this, and when I tried it nothing changed. That probably means it wasn't necessary, but I wonder how wrong the data would be if it became uncalibrated and I failed to calibrate when necessary... and how do I know when I need to calibrate! I really like the mAh and mWh resettable readings as it gives a good way to test battery capacity and efficiency (how much power it takes to fully charge vs how much power you get out of it!) I suspect a lot of people buy these for testing something and return a month later, but I think for the very small price I'll keep this on hand. ... show more

Great little device, very easy to use, I use it with everything I’m charging to see how much watts each device needs or use, I especially got it for the Steam Deck and Asus ROG ally to see exactly how much power each device uses when playing on a external display or on the main display, or even when not in use and just charging. I wish the display was a bit bigger though. ... show more

    • Robust voltage range is great for battery testing
I like working with USB-C. I also like working with USB-C out of spec; the cable's very convenient, small, plentiful, and cheap; I have lots of male and female breakouts. I've found the device will accept down to right around 3.5V before cutting out (perhaps at the expense of accuracy, but it has seemed within expectations with most LiPo cells meeting their rating). The 3.5V minimum makes it unsuitable for single LiFePO4 cells, but you can run two in series and be fine; it is also almost fully useful for single LiPo cells given their "voltage cliff" in capacity through discharge; you will miss out on capturing maybe 5% of total capacity, and discharge that low is bad for battery lifespan, anyway. The neat thing about it handling higher voltages is that my DIY power sink is also reasonably voltage-tolerant, so I can still capture full Ah and Wh I need without adjusting anything -- but if I needed to, I could also move a linear regulator downstream of this wattmeter device (into my sink circuit) and get 5V out without introducing the huge inaccuracies which would come from having the regulator upstream of this wattmeter. Though from a cost/value perspective, I would say this device is essentially already perfect, a feature I would appreciate in a future revision or separate "power-user SKU" is a programmable voltage cutoff, where the device would flip a relay; or the cheaper/simpler option may be to close the circuit when the screen shuts off at ~3.5V, and this would be suitable for single-cell LiPo testing without risking dangerous overdischarge (though it was not too much expense or trouble to rig up an auto-cutoff myself in the power sink circuit with a relay and a comparator IC). I'll grant I'm probably in a pretty small niche of people who would appreciate that, though; there may not, in fact, be dozens of us. ... show more

As titled, looks like I received a worn down, used item. Two significant scratches on the screen. Dead pixel almost in the center of the screen, above the W on the third pic.

    • Great tool to verify USB charging and device power use
With USB-C PD capable of providing well over 100 watts of power, this is a fine tool to see what is used by anything hooked up to same. From high-end laptops to Pine64 soldering irons and nVidea Orin AGX development kits (65 watts), it comes in handy during product design, prototyping and debugging. I'm sure its accuracy is not laboratory instrumentation grade but since the USB wiring isn't accessible and we only need a few digit accuracy in the readings, it serves very well. Bravo! ... show more
