A:AnswerI bought it for this purpose but it WILL NOT work well.
There is a low pressure/high volume hose that will fill it 75% with the correct adapter (not included). It will not get it to even 1PSI and you need 15PSI for a paddle board.
You can switch to the high pressure hose with yet another adapter but I was getting about a half of a PSI per 2-3 minutes.
Long story short, it's doable but will take like an hour to fill and you'll need to buy two different adapters.
