OBD2 To USB Power Adapter Cable — Overview
This OBD2 to USB power adapter cable plugs into the diagnostic port to power dashcams, ambient lights, and other 5V USB accessories without cutting or tapping factory wiring. A mode selector lets this OBD2 to USB power adapter cable switch between 24-hour always-on output and ignition-based ACC power.
OBD2 USB Power Cable with Selectable Always-On or Ignition-Based Output
Why This Product Exists
Hard-wiring dashcams or accessories usually requires fuse taps, panel removal, and permanent wiring changes. Many users want a simpler solution that:
Does not involve cutting or tapping factory wiring
Is easy to remove or transfer between vehicles
Allows control over always-on vs ignition-based power
This OBD2 to USB power adapter solves that problem by using the vehicle’s diagnostic port as a power source, combined with a physical mode selector.
Where It Is Used
The adapter plugs directly into the OBD2 diagnostic port, typically located below the dashboard. The USB-A female port is then used to power:
Dashcams
Ambient light controllers
USB accessories
GPS modules or trackers
Because it uses the OBD port, installation is tool-free and fully reversible.
How the 24H / ACC Switch Works
The built-in switch controls power behaviour:
Switch ON (24H Mode)
USB port receives power continuously
Suitable for parking surveillance dashcams or trackers
Switch OFF (ACC Mode)
Power turns off automatically after ignition / ACC is switched off
Ideal for daily-use dashcams and accessories
This logic removes the need for complex wiring decisions.
Installation Notes
Plug the adapter into the OBD2 port
Connect your device to the USB-A output
Select desired power mode using the switch
Route the cable neatly along dashboard trim
No coding, fuse tapping, or electrical modification is required.

FAQs
This cable carries a 6 month warranty, with an exchange-only return policy.
In 24 Hour mode the USB port stays powered continuously regardless of ignition state, which is intended for parking-surveillance dashcams or trackers that need to keep running while the car is off. Since the output is a low-current 5V USB feed, drain depends mainly on what your connected accessory draws, but leaving it in 24 Hour mode for long parking periods will use some battery power continuously, so switch to ACC mode for everyday driving if you don’t need parking coverage.
No. The adapter only draws low-current power from the OBD2 port, and vehicle diagnostics functionality remains unaffected.
Yes, ambient lights are one of the listed applications for this adapter, alongside dashcams, USB accessories, and GPS modules or trackers.
No. There is no coding, fuse tapping, or electrical modification involved. You simply plug it into the OBD2 port and connect your device to the USB-A output.
The USB-A female output is suited to 5V USB accessories such as dashcams, ambient light controllers, GPS modules or trackers, and similar low-current USB devices.
There are two modes. With the switch ON, the USB port stays powered continuously in 24 Hour mode, suited to parking surveillance dashcams or trackers. With the switch OFF, it runs in ACC mode, where power cuts automatically once the ignition or ACC is switched off, suited to daily-use dashcams and accessories that shouldn’t drain the battery.
Yes. Since it simply plugs into the OBD2 port with no cutting or fuse tapping involved, it is tool-free, fully reversible, and easy to transfer between vehicles.
It may not be ideal in that case. This adapter is not recommended if the vehicle’s OBD2 port is already permanently occupied by another device.
No. It is not intended for accessories that need high-current power output or a hard-wired trigger signal.
Any vehicle with a standard OBD2 port, including Volkswagen, Skoda, Hyundai, Kia, and Tata. Compatibility is based on OBD2 port presence rather than a specific vehicle model or platform.
