Auto Surge Protector 12V/24V with sound
Designed to protect on-board electronics from the voltage spikes that may occur while employing electric power from an external source for
fast starting purposes (battery connected to another vehicle or booster). This appliance is simple and quick to use.
Connect the two clamps to the battery poles. The red light indicates operating voltage (12V/24V).
The buzzer sound indicates the presence of voltage spikes that the surge protector is dispelling.
