Let me know.

Haha I have 3 sizes. My order links are dead but search for voltmeter watt meter. The tiny one with .000 resolution is hard to find. In the same shape it usually comes in .00 resolution. You can tell accuracy is all over… theyre off by different amounts over the voltage range, and the ones I have cannot be calibrated.

30q for scale.

The tiny one feels the most fragile and has bad viewing angles. The big one is the best to use of course. I like the one on top but the reset button is recessed grrrr.

Thanks, yeah, I have exhausted Ebay and AliExpress. I am looking for something that is about the size of your smallest one’s display… 5A is fine…

Really just show amps and Volts, no thrills.
