Unfortunately, the power is not enough for a SUP. It also doesn't have the right attachment for a SUP (neither for the Bestway Hydro-Force nor the red paddle).

Since a total of 3 attachments are included, this should actually be possible. However, I can imagine that the pump does not provide the (air) pressure that is needed for a SUP to be fully inflated. With my inflatable boat, I also have to use the hand pump for a short time at the end. But at least 90% is already inflated.
