100 feet is the maximum distance allowable between the inflatable and the source of electrical power. Here’s why, the longer the distance the greater the loss of power. Even with the heavy duty commercial grade extension cords we use, the voltage drop over 100 feet is significant. The fan motor which keeps the inflatable full of air requires a set amount of voltage at all times. When an excessive amount of cords are run, the voltage drops causing the fan motor to run slower and hotter. This can result in 1) tripped circuit breakers and/or fire 2) fan motor failure 3) slow fan motor speed and inadequate inflation. In cases where the set up location is more than 100 feet away we will require the use of a portable electric generator. A Bounce Above the Rest rents generators, however, they are not routinely carried on our delivery trucks and must be reserved.
