If you can get bigger, that's always better. Better to have more power than you need than not enough and have to rotate more things on and off the the power. This calculator will give you a ballpark on your needs. http://www.generatorsales.com/wattage-calculator.asp Really you should go to each thing you want to run and see specifically what power needs you have. I also recommend having an extra spark plug or too, pull cord, etc so that if power goes out and something happens, you can fix it right away. Oh and remember the thing won't run without fuel so having filled fuel cans is always a good idea. If you get it, do a tune up on it. Run fresh gas, clean carb, plug, air filter. Run it, hook stuff up to it, before you need to so you know it operates properly. If you run it outside, chain the hell out of it because its common for them to be stolen in an emergency. If you can secure it in a garage or basement, make sure it's exhausted properly or you'll die from carbon monoxide. I rent so hooking it up to the house isn't an option. Mine has a corded remote that I can bring inside and plug into as well as start/shut off the unit.
