We keep a electric air mattress pump (coleman brand from walmart) on board to blow up floats, rafts, tubes, you name it. Mine is an 800 watt, I have even ran my small shopvac off of it while on a beach camping trip. The electric air pump works a ton better than one that we had that was DC. This thing doesn't mess around! I was inspired by KG last year when we went out with them and he had one stowed away and pulled it out to plug in his margarita machine. Love having it!
