Best way to pump up an inflatable SUP....without the manual pump

[capobeachboy]

Been using this one for a couple years and it works great. ULI boards got this a replaceent for the Bravos a few years ago and modified it by installing a longer hose and a breather so it tops out at 18psi (I capped mine off for higher pressures but don't walk away and forget you're pumping cause it can reach about 80psi).  It fits the ULI valve but you just need to change out a rubber washer on the attachment and it will fit any other iSUP. It's heavier than the Bravo but very robust.

Oops, I see I pretty much already said all that. I should read back before I post.

We have a Red 12'6" Elite and 9'8" Ride.  The best option I've found for inflation is a Viair portable compressor:

Combined with any adapter (I use this: https://greenwatersports.com/shop/red-paddle-co-inflatable-sup-schrader-valve-adaptor), it takes about 15 minutes for the 12'6" to reach 20-25psi.

All things must be considered.
