Answer 1 -- Some OptionsThat depends. For example, I have an old, small [5 inch] B&W TV that was designed to be portable. It operates on "C" cell batteries [8 of 'em] placed in a compartment inside the TV, or on an auxiliary 110-120 volt AC to 12 volt DC battery "eliminator" transformer that plugs into a household wall receptacle. It also has a power cord with battery charger type "clamps" so I can hook it up directly to the terminals of any automotive battery.

For ordinary TVs that are designed to operate only on 110-120 volt AC, you have to use what is called a POWERINVERTER.

The Inverter either plugs into an automotive Cigar/Cigarette Lighter socket, or any similar 12 volt DC power socket, OR using cables [look like jumper cables, but they are permanently tied into the Inverter] which attach to the Positive and Negative terminals of any 12 volt DC automotive battery.

Inverters are available in several different sizes [amount of electrical current output capability specified in Amperes (Amps)]. The inverter output must equal or exceed the Amps required by the TV set, or any other 110-120 volt AC device one wished to power via an Inverter.

How long can a tv run on a 12 volt battery?
