2 In 1 Function: The voltage gauge monitors battery voltage and power in real time. Voltmeter test range: DC 5-48V, accuracy ± 0.1V. Power test range: 0-100%, accuracy ± 0.1%
Touch Switch Control: You can switch between voltage and battery percentage on the volt meter 12 volt, or turn it off to reduce battery consumption when storing
Multiple Protections: The 12v voltage meter with 10A fuse for overload, overcurrent, and short circuit protection, and IP65 waterproof to ensure safe use
Reverse Connection Protection: If the positive and negative poles are connected in reverse, the 12 volt gauge will not burn out, but there will be no display
Widely Used: The digital voltage display is suitable for DC 12V 24V cars, motorcycles, RVs, SUVs, off-road vehicles, ATVs, boats, marines, ships, trucks, tractors, etc
