The readings aren't very accurate but a cute little device and the seller is good.

So far so good. It reports volts, amps, watts, direction, and accumulated power. It appears to be accurate--agreeing within a few percent of the reports of other devices in the power supply chain.The auto-rotation feature is sometimes useful and sometimes annoying.The graph feature is kinda lame in my use case. The time scale is way too short for me.It was pretty difficult to figure out how to get into english output mode, but eventually I got there and got it to persist.If I had a wish, I'd wish that it could provide some PD/PPS information, so that we can compare what was requested vs delivered. I took at the voltage and I don't know if it is voltage drop across the cable or poor power supply or simply not requesting the voltage I think it might be requesting.

Does what it is intended to do, namely measure voltage, amperage, and wattage. Accurate results when compared with more expensive test equipment. Please note that the USB-C standard requires that a load be present (i.e. input and output connected) in order to turn on and provide a reading. Changing the display language from Chinese to English was frustrating and time consuming with the vague menu selection buttons. Small, yet clear display.

Very cool gadget. Clear legible display, many features, actually includes readable instructions. Couldn't ask for more, especially at this price. I may buy another one just to have two!

I would probably give it 4.5 stars if we had half stars.I like the device especially that it is bidirectional in that it can be plugged into the charger or the device.It is smaller than I had envisioned but the screen is easy to read. with large letters and high contrast colors.`The 2 buttons are tiny for us handicapped oldsters. They take a short and long press so 4 functions on 2 buttons. A little confusing at first but I just found the setting I like and don't see the need to change it.I don't have a calibrated meter to compare it but my iPhone draws 19.7 W from my 20W charger and 19.8 from a power strip with USB ports. A USB hub, my slow charger measure 7.4W. My Fire 10 draws 11.8 W. These are very close to what I expected.It is also informative to watch a device -charge to 100%. It goes to zero for a few seconds then charges for a few seconds in and endless cycle.making it clear why we should leave it any device plugged in long after charging is complete.

In a nutshell: HARD recommend for DIYers and the generally curious. Super strong utility and relatively plug-and-play.So, I originally got this device expecting it to only be useful on a project involving a Raspberry Pi 4B, so I can get a gauge of how much power consumption it has, but knowing the power consumption is so darn important that I find myself using it all the time. I'd connect it inline with my phone to see the adaptive charge rate, hook it up to some HAM radios of mine to optimize the power consumption, and loads of other things. Honestly, this is a hard recommend for anyone who wants an idea of their power consumption through a USBC connector, and doesn't want to fiddle around with the encumbersome clips a multimeter requires. Honestly considering putting one of these in my Cyberdeck, just to keep mental tabs on its power use.

Tiny device, more than accurate enough to tell you what you need to know. Helped me figure out a couple non-functioning "high-power" USB ports.

This is a useful, impressive and annoying little meter.The screen fonts and the screen itself are so tiny it's hard to use.The entire screen is smaller than my thumb with controls that are not intuitive.Sometimes UP goes up. Sometimes not.If you turn it over, up is now down.Hold on, , it flipped over. So...up that was Down is now up agai. Right? or not.Sometimes UP also sets other variables, Or not. Then you have to figure out how to get into or out of edit mode with only 2 buttons while the same 2 buttons also control up/down.Down goes down except when it doesn't.Sometimes neither button does anything.Hoooold the button sometimes works. Sometimes not.2 buttons for everything depending which one is pushed first, how many times and how long was it pressed while also blended with what mode or page was it on at the time is not intuitive.It device won't communicate or turn ON when connected to most USB-C chargers or batteries.It remains off unless you connect a load to it.Apparently it doesn't communicate on it's own so it remains off.Another "feature" with no purpose is having an entire menu page dedicated to a 3 second auto-count-down timer that shuts off the screen without asking. Drat. Off again.They really want the screen OFF while I keep trying to keep it on.A whole page dedicated to turning it off is pointless.That's a page we have to avoid for the life of the product and it keep coming up as we try to get back to the main page. You have to go around to get back and watch out for auto shutdown.It doesn't need that menu at all with a page that forces auto shutdown.I looked a while but I don't see what B-VoL 3.0 to 3.7 to 5.0 is for and why it shows 2 -3 different values for the mAHr at the same time. 3000, 4400 and 5300mAH. which is which?It's a useful meter with a nice but tiny color screen that's awkward to use.
