Universal 12V Dash Cam Power Adapter–Dual DC Buck Module 12V to 5V, Dash Cam Mirrior Camera Wire Kit, Quick Installation, Plug and Play

Features

• 【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.
• 【Clean Installation】This dashcam power adapter DC Dual USB Buck Module is easy to install and plug and play. （note: that this universal adapter cord does not provide continuous power and will only work when the vehicle is started.）
• 【Dual USB Buck Module】Equipped with 2 USB buck modules, each outputs 5V2A max. Please note: the current of a single device is best not to exceed 2A (the current of the dashcam/GPS is about 0.6A), you can unplug one for spare if you only need to use a single USB.
• 【Including 3 USB Cables】We provide micro/mini/type-c USB charging cables to power GPS, e-dogs, phone charging stations with wireless charging, and more.
• 【Installation Method】 Use a multimeter—do not guess by wire color alone—to find the +12 V 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 ~12 V 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.
