More details on the Garmin Constant Power Cable

Product Research


Overview: The Constant Power Cable provides power to Garmin Dash Cameras without taking up a 12V power port. The 12" cable plugs into your vehicle's OBD II port, and provides constant power to two Type A USB ports. This lets your Dash Camera to continue to operate in Parking Mode with the engine off. The Constant Power Cable can also power or charge most any electronic device that requires USB power. A 3-way switch on the OBD-II plug lets you choose the duration of the power output. The cable is not compatible with commercial vehicles with a J1939 connector.

OBD II Port: The OBD-II (On-board Diagnostic) port is a female 16-pin port on most passenger vehicles, usually located near the steering wheel. Plugging the Constant Power Cable into the OBD II port connects it to battery power (constant), ignition power (switched), and chassis ground to power the two USB ports.

USB Output: The USB connector features two USB-A ports, each with a 5V 1.5A output. It allows you to power your Garmin Dash Cam with one port, and one other device, such as a smart phone. An adhesive-backed hook-and-loop pad is provided for attaching the USB connector to your dashboard.

Time Switch: The Constant Power Cable's Time Switch lets you determine the length of time the device continues to supply power after you exit the vehicle. The switch has three positions: 10 minutes (10m), 24 hours (24h), and Always On (∞).
