Designed to safely hard wire and power dash cams or devices with Micro or Mini USB, Gator GUNIHWC is a simple plug and play solution that supplies power to any dash cam or device. It's compatible with 12V/24V DC for car or truck installations. This means GUNIHWC provides constant power supply to your dash cam when the engine isn't running. While its Battery Drain Protection mechanism ensures your dash cam won't drain your vehicle battery, the battery itself will stop relaying power to your dash cam, as soon as it detects your battery level gets too low.
