can it be run from a 12v battery?

I've got a TV Screen that apparently has come from a caravan: How do I run it from a 12V Battery: Here's the info from the Adapter Box: EDACPOWER ELEC: MODEL EA1050A-120 AC INPUT 100-240-1.8A, 50-60HZ DC OUTPUT 12V --- 5.0A One end of the Adapter has a plug at the end of a wire similar to one of those AC/DC Adapters then you have the box which has the Kettle Plug type Pins. Can it be run from a 12V Battery and if so do you know how?

Forget the adapter, what's the TV say? Though if that adaptor powered the TV from an (100-240V) AC supply, then yes - it seems like a 12V DC powered TV with a maximum 5A draw (=12x5 =60W @ 12V, or maybe 13.8x5 =69W @ 13.8V, etc - though that 5A represents a "maximum" average current draw). It can therefore be connected to the battery through a fuse (say 5A, but maybe larger (7.5A or 10A), or a slo-blo type) making sure that the polarity is correct (+ to +12V, - to ground). Actual implementation can vary - anything from cigar socket to a relay-controlled circuit; maybe with low voltage cutout. It depends on your desire, interference, power delivery issues etc. FYI - the TV at ~60W is a similar load to ONE traditional low-beam headlight - ie, 55W.
