Dash Cam Power Adapter (12P Type C) Fit Toyota/Lexus - Hardwire

Our review of the Dash Cam Power Adapter (12P Type C) finds it best for Toyota and Lexus owners who want a clean, hardwired dash camera installation using the vehicle's lane assist power source. The bottom line: this adapter makes a near-permanent dash cam or GPS installation tidy and reliable by tapping the lane assist 12-pin connector rather than the mirror power feed, and it includes multiple USB cable ends so most cameras fit without extra parts.

Key Features

• Vehicle compatibility: Designed specifically for many Toyota and Lexus models, it ensures a proper fit when the vehicle has lane assist.
• Lane assist power source: Draws power from the lane assist 12-pin interface to provide a stable hardwire connection separate from the auto-dimming mirror circuit.
• Dual USB outputs: Two USB ports each include a 12V-to-5V step-down module, allowing simultaneous powering of two devices at up to 5V-2A per port.
• Three angled cable tips: Ships with left and down 90 degree mini USB cables plus a 90 degree Type-C cable so it fits about 98% of dash cams, mirror cameras and GPS units.
• Installation guidance: Interface comparison images and diagrams are provided so installers can identify the 12-pin connector under the front sensor cover and route the cable correctly.
• Customer-proven fit: Reviewers report ease of installation and reliable operation on compatible models such as the RAV4 2019.

Who It's For

This adapter is aimed at Toyota and Lexus drivers who have lane assist and want a neat, hidden hardwire for a dash camera or GPS unit instead of a cigarette lighter or mirror tap. It is particularly useful for owners of RAV4, Highlander, 4Runner, Sienna, Tundra and the listed Lexus models who prefer a semi-permanent installation and the ability to power two devices.

Not suitable for vehicles without lane assist or cars where the 12-pin interface differs from the models listed. Buyers who cannot confirm their model year, interface type, or that the connector is the 12-pin under the front sensor cover should consult the compatibility list or contact the seller before purchase.
