Review on BUYMAX Electric Air Pump for Inflatables - 110V AC/12V DC Air Mattress Pump for Airbeds, Boats, Pools, Rafts, and Inflatable Pool Toys - Portable Pump with 3 Nozzles by Kris Wagner

Looks like a great inflator. I already have a Ryobi battery powered compressor/blower, but it's not really rated for the air volume in large inflatable boats. This is more true in high PSI and low volume situations. I've only encountered one problem, and it applies to pretty much all of these inflators: make sure you have reasonable expectations of how much air can flow through the hole. Straw. If your inflatable boat has large valve holes, this will happen very quickly. If, as in many cases, the opening is <0.25", it takes much longer. Still smaller than my Ryobi and I don't have to hold the trigger the whole time. - Displacement and high PSI compressor to do more. It costs >10x.
