Power Adapter 3-Pin for BMW and MINI F/G Chassis - Dash Cam Power

In this review of the Power Adapter (3-Pin) for Dash Cam, the author finds it best suited for BMW and MINI owners who need a tidy, vehicle-integrated power solution for a dashcam or radar detector. The single biggest reason to buy is the combination of both 5V and 12V outputs plus a clear LED display showing current and voltage, which removes guesswork when installing electronics behind the rearview mirror. Installation is plug-and-play for compatible F Chassis and G Chassis models and does not interfere with the rain sensor or vehicle warranty.

Key Features

• Dual voltage output: Provides both 5V USB power and a 12V DC output so you can run USB dashcams and devices requiring 12V from one adapter.
• Six output cables included: Comes with two DC 3.5mm cables, an RJ11 cable and three USB variants so most dashcams and modules will connect without extra purchases.
• LED display: The built-in screen displays current and voltage so installers can verify proper power delivery at a glance.
• Vehicle fit: Designed for BMW and MINI F Chassis and G Chassis that have a 3-pin connector behind the rearview mirror bracket, reducing wiring complexity.
• Easy installation: Uses a special wiring harness connection that is plug-and-play and claims not to void factory warranty or affect the rain sensor.
• Brand support: FitDVR produces dash cam power adapters and offers customer support for questions or compatibility needs.

Who It's For

The adapter is ideal for BMW and MINI owners (F and G Chassis) who want a neat factory-style feed for a dashcam, radar detector or USB-powered accessory and who can confirm a 3-pin connector behind the rearview mirror bracket. It suits DIY installers and professional fitters who value an LED readout and multiple cable options so they do not need separate converters.

Shoppers who do not have the specified 3-pin mirror connector or who drive models outside the stated chassis should look for a model tailored to their vehicle. This adapter is vehicle-specific and not a universal cigarette-lighter replacement.
