Review on π‘ SMAKN 0.56-inch 2-Wire Blue DC 3.0v-30v LED Panel Digital Display Voltage Meter Voltmeter by James Holker
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.
- Great for a small home
- Some cons
