About This

• 【Installation Method】Use a multimeter—do not guess by wire color alone—to find the +12V and ground terminals on your car's connector. Insert the adapter's red wire into the +12 V slot and the black wire into ground, ensuring metal-to-metal contact. Start the vehicle and verify ~12V with your meter. Then plug in the USB buck module; its LED indicates normal operation. Secure the harness with tape. A brief misconnection won't damage the module, and ensure metal contact is good for stable operation.
• 【Universal Dashcam Power Adapter]】Fits any live 12 V source in your vehicle—auto-dimming mirror, reading lights, lane-assist, or rain-sensor harness. Be sure to tap a true 12 V circuit; if you connect to an unpowered line, your dashcam or GPS won't turn on. Only compatible with standard 12 V systems. Not for 24 V vehicles or those with delayed start, smart sensors, or other special circuits. Ensure a true 12V line is tapped for proper operation; connecting to special or delayed circuits may cause the dashcam not to power on.
• 【Wide Compatibility】Our dashcam mirror camera power adapter has a wide range of compatibility and can be adapted to different models of dashcams: V300, F7N, S7, N4 Pro, A229 Plus, N470, M300, A119, M550, N2Pro, N5, A229Pro, F9, S80, HK3, E1, T1, S1 Pro, D30S
• 【Note】Be sure to make sure that the USB indicator light of the adapter is on before connecting the Dashcam, GPS, etc., to prevent the device from being damaged. The USB indicator light confirms the power is correctly supplied and the module is ready for use.
• 【Dual DC Buck Converter Output】DC 12V/24V to 5V USB step-down module has been tested by 5V 2A continuous work for 48 hours, which is safe and reliable. For stability reasons, make sure that the current of a single device does not exceed 2A (about 0.6A for dashcam/GPS) before installation. Please note that the USB port only provides power when the vehicle is started and does not supply continuous power.
• 【Intelligent Protection Function】Our dash cam mirror camera GPS hardwire kit has built-in intelligent protection mechanisms such as over-current, over-voltage, short circuit, etc., during driving. If there is an abnormal situation, it can quickly cut off the power supply, prevent the dash cam from being damaged or cause potential safety hazards, and escort your driving safety. The power cut-off is a safety feature and not a defect, ensuring the dashcam and vehicle electronics are protected.
