Review on πŸ’‘ SMAKN 0.56-inch 2-Wire Blue DC 3.0v-30v LED Panel Digital Display Voltage Meter Voltmeter by Justin Miller

Revainrating 3 out of 5

Reasonable price, good day and night vision, just right for most needs.

I use them to monitor 2 24VDC batteries. Each battery voltage can be displayed at a 12 volt or 24 volt setting in combination with a shutdown setting to avoid wasting energy if not monitored for charging issues such as a low battery. I have a blue and green display, both are accurate, I can tell to within 0.05 volts, and it's wise to buy one for each 12 volt battery I use for my solar arrays.

Pros
  • Quality build
Cons
  • Some little things
