Hi I have a small avtex 15 inch tv that i like very much .it has a good picture and the sound with speakers in the front is perfect.Up to now ihave allways used it on mains electric on hookup,but over the weekend we stayed in a carpark over night in north Wales, so used the 12v plug that came with it. The red on light came on but i failed to get it to go with remote or manually so assume the 12v is faulty' My question is .What size inverter would do?. I would also like to charge my laptop as well from it. I thought possibly a 350 watt should be enough .Any help would greatfully accepted. Cheers Keith.
