Having a cordless air compressor is incredibly convenient. We keep one in our car, and now we’ve added another to our boat. This model features a built-in rechargeable battery that charges using the included USB cable (note: an AC adapter like the one in my picture is not provided). It also has an LED display that shows the battery level as well as a selection of inflatables to preset the PSI, or you can set it manually.Alternatively, you can power it using your boat or car's 12V outlet (if you have one) —though keep in mind this method powers the compressor but does not charge the battery.We primarily use this compressor on our boat to inflate water toys and a paddle board. Since our boat doesn’t have a built-in 12V outlet, I purchased a cigarette lighter socket adapter from Amazon. It’s a handy addition that also allows us to power other accessories, like a floodlight.This compressor comes with a case to hold it and all the accessories so its easy to store.
