Standard televisions connect into an 120 volt electrical sockets. However, if you are on the go most vehicles do not have such an outlet built into the vehicle. This is where the 12V DC cigarette outlet comes into play. It is possible to convert the 12V DC outlet to an AC power port. This instantly allows you to hook up your television to the car's power source (televisions do not use all of the 120 volts provided by the electrical home outlet so you do not have the risk of blowing out the vehicle's DC power source).
