The Nordrok dual power aeropump is an electric pump that can be powered via DC 12v adaptor (lead included) or by 8 x AA batteries (not supplied), making this pump easy to use, whether you are on the beach, on the campsite, or away from DC power. With a large capacity air output, it will rapidly inflate (or deflate) most inflatable items. Three valve nozzles are supplied to fit various inflatables, from beds to paddle boards.
