Airhead Hi-Pressure 12v Pump

I bought a sofina carribean island raft. At 10 feet by 13 feet the raft is too big to inflate at the dock so I needed a 12v pump to fill it. I did a dry run inflate on shore using a spare battery. Inflated the entire raft, including 4 backrests, the boarding platform and the slide in under 10 minutes. Raft was plenty firm for me to walk on with only about a 2" depression (I weigh 210). Deflated it also in about 10 minutes. Sucked each compartment flat. Absolute great pump! Only possible problem is the 10 foot lead could be longer to reach from the battery compartment to the back of the boat (or side gate).
