Effortless Inflation The O'Brien ISUP Electric Pump is a 12-Volt, high-pressure pump that pairs perfectly with inflatable stand-up paddleboards, inflatable docks, and our drop stitch floats (Runways, Party Pits, and Yoga Floats). Powered via a car plug, use the buttons on the handle to designate your desired pressure (adjustable from 1-20 psi) and let the pump do all of the work. It will automatically shut off when it reaches the specified pressure, so you can immediately start enjoying your time on the water.
