I was wondering if anyone could point me in the right direction for a power inverter. I'm looking for just emergency backup electricity for the winter months, jut enough to run a couple lights and a radio. No heavy stuff like running a freezer or stove. I don't want to buy a generator. I have a couple deep cycle batteries in my boat that I'm thinking would store enough juice to run lights and a radio for a few days if needed. Does anyone have any experience with power inverters ? If so, would you have any recommendations ?

Thank you.
