Thanks for the info. Inverters come in ratings as low as 75 watts, maybe even less. If 400 or 750 is not enough wattage, I have seen models available online in the 1000 to 1500 watt range for $100 to $150 or so. The one at Lowe's for $29.99 is a good deal. I seriously doubt you'll find a comparable model for less. Even Walmart is about $15 more. The one I have, the 400, includes a cigarette lighter adapter, as well as battery clips, for heavier electrical loads. The 750 does not include the cigarette lighter adapter, otherwise I probably would have sprung for that one, even though it's double the price. I'll try mine out later today, just to make sure it actually works.

For me, 400 watts should be enough. I will still have the battery powered devices, and I already have about $50+ worth of D and AA batteries (batteries were very hard to find after Frances hit, and I got them when I could.). Publix seemed to have the best (only) supply of batteries after the crisis, btw. Forget Walmart unless you show up at 4am when the truck is unloaded.
