A modern caravan has basically three electrical systems on board. Two of these systems are 12 volt Direct Current (DC) just like your car and the third is 240 volt Alternating Current (AC) just like your house. The first system is to provide the lights that replicate the road lights on your car.

How does caravan power work?

Most portable caravan generators produce 240 volts of power by connecting a petrol or diesel engine to an alternator; to power sensitive appliances such as computers or phones, youll need a sine-wave inverter generator. Benefits: They will efficiently run most appliances. You can refill them at a petrol station.
