If you don't want to be limited by the "power" of dinky generators, go for broke with the help of Generac. The GP15000E supplies an eye-popping 15,000 watts of power r 10 hours (at 1/2 load). What makes Generac generators different from most generators is that they are equipped with their own OHVI engine, which lasts 3-4 times longer than engines not specifically made for generators. Nobody likes buying more fuel than they have to, which is why you'll dig the automatic idle control (which reduces fuel usage). Does your outdoor event need electricity? No problem; the 13" all-terrain wheels and handle will make transportation easy. Changing electrical loads can be too much for some generators, but not for the GP15000E; the Electronic Governator provides a super quick response in situations like this. Generac makes the best generators on the market, and it isn't hard to see why.
