OBD Power Adapter for Tesla Model 3 / Y / S / X — USB + Type-C, 18W Each

Product Overview

This OBD adapter plugs into the Tesla diagnostic port and turns it into two charging ports — USB-A and USB-C, 18W each. It powers phones, tablets and dash cams without taking up the 12V socket.

Compatibility

Model 3, Model Y, Model S and Model X. The OBD port is on the driver's side, low on the dash near the left knee.

Power

Input 12V from the OBD port. Output 18W per port, 36W total. A built-in fuse protects the circuit.

12V Battery Note

The OBD port stays live when the car is parked. Charging while parked draws from the 12V battery, not the main pack. Unplug the adapter if the car will sit for more than a day.

Safety

The adapter sits at knee height on the driver's side — check that it does not press against your leg or interfere with the pedals. Stop using it if you notice abnormal heat or sparking.
