It works. I bought battery holders that take three AA batteries and plug in to a D space. With 12 AA high power rechargeables, this thing went all summer inflating my Saturn raft. It works quickly and saves a lot of pumping by hand. You do still need to top up the pressure with a hand pump, but it only takes a minute. The biggest bonus was that this pump will also vacuum out your boat. It works fast and collapses the boat completely, making it much easier to fold up and store. I keep it in my dry bag so I always have it.
