If you’re looking to power your television with a car battery, there are a few things you’ll need to know. First, the TV needs to be plugged into an outlet and the car battery should be able to provide enough power to keep it running. Second, make sure that your TV’s power cord is long enough to reach your car’s cigarette lightersocket. Finally, make sure that your TV has an appropriate outlet - most TVs come with an AC adapter - and connect the car battery to the outlet. Once everything is connected, turn on your TV and wait for it to start up.
