What kind of electric generators do I use to supply power for a party?

You need to know how much your total amp. load will be @ 120 volt ac...Then you can reasonably estimate the wattage generator (s) @ 120 volt you will need...It is possible that you might need two generators.. However, Running under a near full load you will probably need to re-fuel the generator (s) about every four hrs. Amp. can easily be converted to wattage
