NRS Super Pump
Here's what other sites are saying:
Yeah, maybe you've been doing lung exercises all winter so you'll be ready to blow up your SUP, raft, or kayak. But you'll still be about four hours behind your buddy, because he's using the NRS Super Pump to get inflated and on the water. It supplies 1. 8L of air per stroke and inflates up to 20psi with no trouble, with a sturdy design and single-action two-handed design that'll show just how much your inflate-by-mouth technique really blows.
