A balloon inflator includes a nozzle adaptor configured to fit over an outlet of an inflation nozzle. A nozzle receipt is provided by the balloon inflator housing to selectively receive the nozzle adaptor and a switch is provided at the nozzle receipt. The nozzle adaptor is adapted to trigger the switch when received at the nozzle receipt. The switch controls the power supplied to the motor, such that different motor operating parameters are realized when the switch is triggered and when the switch is not triggered. In a particular embodiment, the nozzle adaptor includes vent channels that exhaust a portion of the air to the atmosphere when a balloon is fitted over the alternate outlet. |
