Our generators are 7500-8000 Watt (9500-10,000 peak watts) and provides up to 66 amps of power for outdoor events. When you rent a generator we always bring a 2nd generator as backup. A full tank of gas will last 6-10 hours depending on how much of the power we use. For example, if we just use 15 amps of the 66 amps the gas will last 10 hours of run time, but if we use 50-60 amps a tank of gas will last 6-8 hours. A typical inflatable uses 1 blower, but a few of our inflatables use 2 blowers. Most blowers use a 1 hp (horse power) or 1.5 hp motor. A 1 HP blower uses 7 amps and a 1.5 HP blower uses 8.8 amps, but they use more when you start them up so we recommend up to 7 blowers per generator rental.
