Query: no power

Although the rca 5400p has some nice advantages, one major dissadvantage is that there is no adaptor for power other than the battery or the wall plug in. i.e. forget watching more than one movie on trips. Rca at this time doesn't make an a/c adaptor for this unit and doesn't plan to. I've tried 3 different power sources (2 different cigarrette adaptors and 1 power inverter) no luck.Another problem is that the unit gets extremely hot and starts effecting the movie about 3/4 the way through it. you have to stop the movie and let the unit cool down. If I could return it I would and get something else. There's nothing portable about this unit.
