Let’s take a look inside a MEECHER Power Analyzer. This construction and design of meter goes by many names and brands, so here are a few others that look very similar to this. This is not an exhaustive list:

Estink Power Analyzer (Looks almost the same)
Fayleeko Power Analyzer (LCD looks different)
kuman KW-47 Power Analyzer (No backlight on LCD)

Enjoy!
