My power needs for comps are fairly light so I'm thinking of getting an 900 watt inverter like this one: http://amzn.com/B00APL78W2 and hook it up to a deep cycle battery. I would use this setup to power some lights Fri. evening (2 hours maybe), small box fan to keep cool at night, electric knife and a hotplate to warm sauces. During the colder months I might also use it to power an electric blanket at night. Would this setup work? Can anybody recommend a good deep cycle battery? Seems like prices vary quite a bit. Thanks!
