Dongar Dashcam Integrator (10-pin Type B) - Hidden USB-C Power

In this review of the Dongar Dashcam Integrator (10-pin Type B) the bottom line is simple: this adapter is for drivers who want a neat, non-permanent way to power a USB dash cam or accessory from a compatible rearview mirror harness. Installation is genuinely plug-and-play and hides the power cable behind the mirror, which is the single biggest reason to choose this adapter. It is designed for vehicles with a powered or auto-dimming mirror and provides USB-C 5V-12V output, making it a practical choice for modern dash cams and radar detectors.

Key Features

• Plug-and-play installation: Connects directly to the vehicle rearview mirror wiring so no permanent vehicle modification is required and cables stay hidden behind the mirror.
• USB-C 5V-12V output: Supplies modern USB-C power suitable for USB-powered dash cams and other accessories, helping future-proof installations.
• Wide dash cam compatibility: Works with many USB-powered dash cams such as Garmin Mini 2, Garmin Live, Vantrue N2 Pro, Viofo, 70Mai and similar models for straightforward power delivery.
• Accessory support: Also usable with radar detectors and GPS units that accept USB power, expanding its usefulness beyond dash cams.
• No constant battery drain: Powers connected devices only when the vehicle ignition is on, preventing unintended battery drain for most users.
• Complete kit: Ships with one adapter and two shorty USB cables (USB-C and Micro USB) to support common device connections out of the box.

Who It's For

The Dongar adapter is best for drivers of compatible Toyota, Lexus, and Subaru models who want a discreet, reversible power solution for a USB dash cam or radar detector. Installers and DIY owners who prefer a tidy look with wiring hidden at the rearview mirror will appreciate the plug-and-play approach.

It is not for owners who need constant parking mode power or those with vehicles that lack a powered or auto-dimming mirror, since the adapter requires a powered rearview mirror and only activates with the ignition. Also, if your device uses a barrel jack or RJ11 connector you will need an extra adapter cable.

Pros & Cons

Pros

• Easy hidden install that avoids cutting or altering factory wiring for a clean finished look.
• USB-C 5V-12V output supports modern dash cams and accessories for broader compatibility.
• Includes short USB-C and Micro USB cables so basic setups work immediately out of the box.
• Ignition-activated power prevents battery drain during parking for most users.

Cons

• Requires a powered or auto-dimming rearview mirror so it will not work on mirrors without power or illumination features.
• Not intended for parking mode or constant power applications without upgrading to a dedicated constant-power solution.
