MECHEER PM01-US-W, the reading stays
It keeps its readings when I unplug it.
The MECHEER PM01-US-W I use keeps its readings when I unplug it. I run a power station down until it dies to test its real capacity, plug the meter back in, and read the results without losing the data.
Well-known alternative. We own a P3 Kill A Watt P4400 too. The MECHEER is our pick.
