Car Power Adapter MIO for MiVue 803PRO / 903PRO / R860WD — 3‑pin cigarette lighter plug

The Car Power Adapter by MIO is a replacement in-vehicle power lead designed for MiVue 803PRO, 903PRO and R860WD dash cameras. It connects to the recorder via a dedicated 3‑pin connector and to the vehicle cigarette lighter socket (12V) to supply continuous power for normal operation, parking surveillance modes and firmware updates while driving.

Advantages

This power adapter offers a direct 3‑pin connection to compatible MiVue dash cams for a reliable electrical contact and simplified installation. The cigarette lighter plug provides standard 12V input compatible with most passenger vehicles, ensuring uninterrupted recording during trips and when in parking mode. The cable assembly is intended to maintain stable voltage and is suitable for powering the camera without additional adapters.

Suitable for

• Owners of MiVue 803PRO, 903PRO and R860WD dash cameras who need a replacement or spare car power lead.
• Users who require continuous power for long drives, fleet vehicles or taxi use.
• Situations where parking mode monitoring and firmware updates must remain active while the vehicle is powered.

When it may not be suitable

This adapter is specifically made for MiVue models listed and uses a proprietary 3‑pin connector; it will not be compatible with dash cameras that use different connector types. It also requires a vehicle cigarette lighter or 12V socket; vehicles lacking such an outlet, or installations requiring a hardwired connection into the fuse box, will need a different power solution.

Key specifications

• Connector type: dedicated 3‑pin plug for direct connection to compatible MiVue dash cams
• Input voltage: nominal 12V from vehicle cigarette lighter socket
• Intended function: continuous power for recording, parking mode and firmware updates
• Application: in-vehicle power lead for passenger vehicles with 12V outlet

How to use

Insert the cigarette lighter plug into the vehicle 12V socket, route the cable safely along the windshield edge or trim to the dash camera, and connect the 3‑pin plug to the camera’s power port. Verify the camera powers on and that recording or parking mode is active. When not in use, unplug the adapter to avoid draining the vehicle battery if the camera does not manage power automatically.

What to consider before purchase

• Confirm your dash cam model is MiVue 803PRO, 903PRO or R860WD and uses the dedicated 3‑pin connector.
• Ensure your vehicle has a functional 12V cigarette lighter or accessory socket.
• Decide whether a standard cigarette lighter plug is sufficient or if a hardwired solution is required for permanent installation.

Usage recommendations

For reliable operation, route the cable away from airbags and moving parts, avoid sharp bends, and check the connection periodically. If you need uninterrupted parking recording for extended periods, consider a professional hardwire kit or an external battery pack compatible with MiVue dash cams.
