Great little meter

Used to make a diy power supply from and old pc atx. Works great, is not deadly accurate but it will do.

Easy to read

I used it to make an emergency 12 volt power breakout board and this allows me to keep track of the power.

So far works good

The two units that I received worked fine. I compared the displayed current with a hand-held meter; the first one was right on. The second one current was displaying approx 20 ma low, and I was able to adjust it with the potentiometer on the PCB labeled I_ADJ so it was right on. Voltage displayed agreed with the hand-held meter also.

Tried and true

The voltage rating is only 30 vdc that's no problem for me but could be for others also a wiring diagram would be nice I already have a couple so again no problem for me but again more documentation would be nice.

The gauges work like they are suppose to

Easy to mount, very readable. I use them in my electronic projects.

Have only used one meter... so far, so good.

I used this meter to monitor voltage in a 24VDC battery box.

Great, but must see this video

They work great, but not trivial to figure out from the provided diagram. You must see the video, in a well-known video site, by Robojax, "Complete Test/Review of 10A 0-100V LED DC Volt and Ampere Meter", AND see the comment by Peter Kay on how to zero it.
