The Bravo BTP12 Two Stage Electric Turbo Pump is an ultra-fast electric pump. It is made even more convenient with a battery which neatly fits into its carry bag. This two-stage electric pump will rapidly inflate you inflatable craft with a high capacity turbine blower and then switch to a high pressure piston pump to pressurize the hull from 1 to 14.5 PSI. With a full battery charge, you can easily inflate the largest inflatable boats several times over.
