No one really wants to pump up their iSUP manually, leaving you too tired to paddle afterwards! Our iSUP inflator/deflator is quick and easy to use for your inflatable paddle board or other similar items. Our max 20 PSI is higher than most inflators, although most iSUPs only need to be inflated to 12-13 PSI. Simply dial in the desired PSI and press start. The pump will shut off when desired PSI has been reached. At the end of the paddle, use the device to quickly deflate the board.
