Known really wants to pump up their SUP manually, leaving you to tired to paddle afterwards! Our SUP 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 SUPs only need to be inflated to 12-15 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, simply use the device to quickly deflate the board.
