Most, if not all, SUP boards will include a hand pump of some nature. As big as these boards tend to be, it can take a great deal of energy to inflate them. Thus, it is not surprising that some people are interested to know if they can pump it via an electric pump. Well, there really is not a set yes or no answer for this one. Firstly, it depends on the specific board that you invest in. Some will need a special valve for using an alternative method, some will not advise using an electric pump as it may damage the inner walls and some will simply not fit.
But, if you can fit one on the valve that is used for air transfer and there is no warning against using one then there is no reason why you can’t. Just remember to not fill it past the recommended PSI; which should be displayed on the pressure gauge. All in all, it is generally not too difficult to manually pump SUP boards with air. It can just be a time-consuming process.
