Works great and gives plenty of information

Used this to measure the power feeding into a drone charger. Told me exactly what was being drawn, definitely handles max USB-C voltage and current. Just plug and play, no fuss.

This is a fairly basic, but a really neat product! Its a great way to see what voltage, amps, and watts various devices charge at.While this also supports cumulative watt hours charged.. i felt this was a very inaccurate reading, so that is why this gets 4 stars. But overall its a nice product and well worth the minimal cost.

As a hobby, I shoot digital pictures with OM/Olympus mirrorless cameras. I have delved into the rabbit hole of wanting to understand the power draw of a camera when doing an action (such as the difference between using the viewfinder and rear monitor in terms of power usage). For testing, I use a power source that provides a fixed voltage, and I measure the watts that are used and I hook that up to a dummy battery in the camera.What I'm most interested in is the getting the maximum watts used for this operation.With other volt/amp meters, I would need to do a test with bluetooth support, and then go over the graph on the phone to find the max. watts used. This is tedious.So, I went looking for a volt/amp meter that displayed maximum volts/amps/watts on one of the screens, and by pressing a button, I could reset the stats (so I could ignore the watts needed while turn on the camera).This is evidently a rare feature.Several of the newer USB C meters had this feature. I rigged up a 5.5mm x 2.1mm to/from USB C and I did the tests. Unfortunately this meter did not reset the maximum volts/amps/watts display, just the time used (and presumably total watt/amp hour usage, which I wasn't interested in).So I searched again and I found the Makerhawk DC28 meter. Unlike the other meter I had purchased and the Makerhawk C2301, the DC28 takes a 5.5mm x 2.1mm plug in and out, which meant I don't have to use a 5.5mm x 2.1mm to/from USB C adapter, but I can measure the power directly.The Makerhawk DC28 shows the maximum numbers like I want, and when I press the button for 3 seconds, it will reset the maximums without turning off the power to the device. Exactly what I wanted.

It does as what it says on the tin... amp, voltage and whatnot display. Great screen!

It's a nice little unit. Emphasis on "little". This thing is small, which can make reading the screen in some orientations more difficult. But overall it is easy to use!The main downside I have found is that it does not pass through USB data, so some applications won't work. For example, you can't use it to see how much power is going to your phone while also using Apple Carplay or Android Auto. And you can't use it to see how much power a USB device (like a Webcam or mouse) is drawing from your laptop. But it works fine for most charging or power-bank related things. Even so, I am removing one star for this flaw.

Display has lots of information. Note that some of the characters are quite small. Basic voltage and current are easily read. The overall unit is very compact.

I'm quite impressed with this little device. Although I don't usually *need* to know the value of charging current and wattage, it is interesting to monitor, and it may be useful for troubleshooting in some circumstances. The readout is bright and clear. I like the fact that the display orientation can be swapped with a simple double press of the button on the back. (Press once to change display details, twice to reverse orientation, and long press to re-zero the data.)
