Portable Air Compressor 110V - Quiet Small Air Pump with 5L Aluminum Tank, Lightweight Oil-Free for Home, Car Tires, Inflatables & DIY Projects

Wow! This puts 12V tire inflators to shame! Definitely overkill for filling one Schrader valve at a time but with a four tire inflation system it kills it! When using on one tire it's necessary to turn it to the 50% speed because on the full speed setting this puppy pumps more air than a Schrader valve can flow. I can fill 4 35" 285/65/20 Cybertruck tires from 30 PSI to 50 PSI in 4 minutes! Those of you who know how long most inflators take to fill 4 35" tires know it can easily take 5 (or more) times that long.This is not the kind of inflator that will inflate to a precise preset pressure, use it with a pressure gauge on your hose setup and shut it off when you have reached the desired pressure. That said, you can set it to shut off in 5 psi increments. I set mine to around 75 psi and shut it off manually when it reaches around 55-58 psi so I will have 50 psi once the back pressure goes away. That's because this puts out so much air it's building some back pressure, even when filling four tires simultaneously.If you have 120 volts available, as the Cybertruck does, this is the way to go.It's very compact and solid sounding.
