OBD2 16-Pin to USB Charger Cable with Switch for Car DVR and GPS

Hardwiring a dash cam or GPS through the fuse box is a job; plugging into the OBD2 port is a ten-second install. This cable takes the vehicle’s 16-pin diagnostic port and outputs regulated 5 V USB for DVRs, GPS trackers and other always-on accessories — with an inline switch so the device can be cut without unplugging anything.

The protection suite is the reason to buy this class properly: high-efficiency conversion at 95–98% from a 12 V input (88–90% across wider ranges), 2.1 A overcurrent protection, 11.6 V overvoltage protection to keep input spikes from damaging devices, and 11.5 V low-voltage protection detected automatically — so the cable stops drawing before the battery is drained to the point of an unsuccessful ignition. It is compatible with diagnostic tools and accessories with a 16-pin socket.

FAQ

Will it drain the battery?
The low-voltage protection cuts output at 11.5 V automatically — a safeguard, not a licence to leave high-draw devices on for weeks.

Does the switch cut the vehicle or the device?
The device — it breaks the downstream 5 V output; the vehicle side stays untouched.
