If no power port is available, the on-board voltage can be taken alternatively via the OBD II socket. Here, the current carrying capacity can also be reduced.

The power output is with an electrical fuse limited to 8 to 30 amps depending on the consumers connected. The power in your car is not regulated and therefore varies in trouble-free operation between about 10.5 and 14.4 volts, even if be specified as a nominal voltage 12 volts.

Many vehicles are equipped with an additional 12 - volt sockets for connection eg of electrical boxes or consumer electronics often in the trunk or under the rear seat. With newer vehicle models with sophisticated equipment, this equipment is now standard, other vehicles can be retrofitted.
