New to forum and appreciate any and all advice. We now have a 21 foot MH which will be a test bed for future travel plans - not full time but larger and nicer for extensive use. I have been able to get a handle on most things but, as usual, understanding electrical on my weak side. My question is laptop usage. We will not have, althought it would be nice, any mobile net capabality - at least not yet. In the interim I shall be dependent on various hot spots for wi-fi usage. The lap top is 6.3 amps and as I understand it one needs to multiply by 110-120 volts for watts. But I just can't believe the laptop is about 700 watts! Is there a built in transformer which will allow me to use an inverter in the 400 watt range - - I need to use on the road as I have a lot of misc data to imput. My apologies for the ignorance but this sort of thing drives me nuts.? Tom M.........? ? ?
