Here is my base station generator which I believe I purchased for 349 with the gas tanks. It is 3450 running watts with 4500 surge watts. This is on a 110v circuit with a 30 amp circuit breaker. Doing some math the "real" wattage is more like 3300 watts until there is a risk of popping a circuit breaker. This is well within what we need, Honestly in a pinch a 2000 watt tiny generator would work, but having a big pad for additional equipment connected like lights, computer, amplifier etc. is very useful for the project. I actually used this a few days when a tornado came through and knocked out power for nearly 2 weeks. Overall is it just a couple inches bigger than a couple 5 gallon gas cans and even fits in my trunk of my Rav 4 without laying down the seats with both gas cans and more.
On a side note, I really need to spread some grass seed outside for these bare spots. I have a shameless electric car plug in the background, that's a Mitsubishi Imiev.
