Sealed switch cover and an IPX4 rating let this 550-watt blower keep running through drizzle or on a wet lawn, which is where most inflatable setups actually live. The motor spins at 3260 rpm and pushes air at 26 meters per second through a 4.5-inch vent, enough flow to hold a garden bouncer firm. A 25-foot power cable reaches a distant outlet without a second extension lead, and the plug carries a ground fault interrupter that cuts the circuit the moment a fault appears. Input is 120 volts at 60 hertz. Wind pressure measures 1.65 kilopascals. The housing runs 13.5 by 9 by 13.5 inches and weighs 11 pounds, so it lifts by hand into a car boot and stores on a garage shelf between parties. Orange polypropylene housing keeps it visible on grass.
