Review on Chamvis Electric Air Pump: High Power Inflator Deflator for Quick-Fill Air Mattresses, Rafts, Pools, and More - AC 120V, 1.2 PSI 600L/min with Nozzles by Ben Diesel

Model Charmvis HT-388. 120VAC. It worked out of the box. He didn't overheat. He inflated a 10 foot boat in less than two minutes. It comes with 7 hose adapters. The inflatable nozzle is a male bayonet fitting (15/16" OD). It didn't fit my boat's 1" inlet valve, however, so I used a 1" OD hose and one of the adapters that came with it. Exhausting the air becomes easy plugged in (1 1/8" ID). A 1" hose is 21 1/2" long. The switch is conveniently located above and in front of the handle. This is a plastic recessed slide switch. The engine ran smoothly.
