Never guess your battery status again. Our OBD2 Dash Cam Hardwire Kit with USB-C & LED Display gives you real-time voltage visibility and 4-level adjustable low-voltage protection (11.6V/11.9V/12.5V/20min Timer)—so you always know exactly when power will cut off, and your vehicle always starts. True 24/7 parking surveillance with zero battery anxiety. Unlike cheap cables that drain your battery with full-power 24/7 recording, our Type-C OBD charger cable activates genuine low-power timelapse recording while parked and instantly switches to full HD recording when vibration or impact is detected. Smart ACC detection automatically identifies vehicle ignition status—switching between driving mode and parking surveillance without any manual operation. The 20-minute delay-off function prevents your dash cam from power cycling during traffic jams or quick stops, ensuring you never miss a critical moment. Install in under 3 minutes—no fuse box, no ACC wire hunting. Simply plug into your OBD-II port and connect to your dash cam. No wire cutting, no fuse tapping, no warranty voiding. Hidden wiring keeps your cabin clean and frees up your cigarette lighter port. The built-in gyroscope chip with A5-B5 signal pin support (plus free A8-B8 adapter for special models) ensures broad vehicle compatibility—works with most 12V-24V cars, SUVs, and trucks, and is compatible with dash cams, GPS, and radar detectors. Complete kit—everything you need in one box. Includes OBD2 Hardwire Kit (with LED Display), USB-C Cable (13.35ft), Ferrite Core Noise Filter, A8-B8 Signal Adapter, Pry Tool, 4 Zip Ties, and Bilingual Manual. Built-in fuse plus over-current, short-circuit, over-heat, and reverse polarity protection safeguards both your dash cam and vehicle. Ready to install out of the box.
