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

Revainrating 5 out of 5

Suitable for most applications

These are used in meterless power supplies used in amateur radio equipment. Most of these ham radios have a wide voltage tolerance of around 11.5v is also 15.0v. Both gauges showed a slight discrepancy in the voltage displayed, reading 13.4 volts when the actual voltage was 13.7. Not a big deal for my purposes, but keep in mind that these are not precision instruments. The blue display is also very bright if that's an issue.

Pros
  • Great for a small home
