010-12530-23 OBD-II Constant Power Cable for Garmin Dash Cams - 24/7

Our review of the 010-12530-23 OBD-II Constant Power Cable focuses on who needs continuous dash cam power without a complicated hardwire job. This cable is aimed at drivers who want reliable 24/7 parking surveillance for supported Garmin dash cams and prefer a plug-and-play solution. The single biggest reason to buy is the cable's combination of dual USB outputs and an integrated low voltage cut-off, which provides uninterrupted device power while protecting the vehicle battery.

Key Features

• Wide Compatibility: Works with a range of Garmin dash cam models including the Dash Cam 46, 47, 56, 57, 66W, 67W, Mini, Mini 2 and Tandem so owners of these models can enable parking mode without model-specific adapters.
• Continuous Power Supply: Supplies power to your dash cam while the vehicle is off, enabling round-the-clock monitoring and recorded footage for incidents that occur while parked.
• Dual USB Output: Two USB-A ports let you power two dash cams or an additional USB device at the same time, adding flexibility for multi-camera setups or charging a phone.
• Low Voltage Protection: Automatically shuts off when the vehicle battery drops below 12V, preventing excessive discharge and helping preserve the battery life of the car.
• Time Control Switch: Three selectable modes (10 minutes, 24 hours, always on) allow easy tailoring of parking surveillance duration to match different needs and battery concerns.
• Plug-and-Play Installation: Connects to the vehicle OBD-II port for a quick, tool-free setup that avoids splicing wires or professional installation.

Who It's For

The 010-12530-23 is well suited for everyday drivers and owners of supported Garmin dash cams who want a simple way to enable parking mode without modifying the vehicle. It is ideal for people who value convenience and battery protection via an automatic low voltage cutoff.

It is not for commercial vehicles with a J1939 connector or for users who need a custom hidden hardwire installation; those users should look for dedicated hardwire kits designed for commercial OBD systems or professional installation services.
