Review on πŸ“Ÿ 2PCS Red LED Digital Voltmeter Voltage Meter DC 4.5V to 30V Panel Meter for 6V 12V Electromobile Motorcycle Car - DGZZI by Mark Colbert

Revainrating 3 out of 5

Fragile wires are best in testers

Good thing it came in a pack of 2. When I tried to install the first one both wires broke. The 2nd still works, I installed it on the boat's battery box.

Pros
  • If the input voltage is higher than 30V, it can be irreversibly damaged!
Cons
  • Negative is present
