REI does not carry any battery operated air pumps for an inflatable stand up paddle board, however, there are several available to purchase elsewhere online. You'll just want to make sure that the pump is compatible with the valve on your SUP (if it is a SUP specific pump you should be fine) and take care to not over inflate your board. An electric pump with a gauge is recommended, or you could inflate it most of the way with the electric pump and then finish it off with a manual pump that has a gauge.
Hopefully this helps!
