Why pump by hand if you don't have to? Let the NRS Blast Inflator Pump do the work for you. Its compact size and rugged durability will last for years. 

• This 12-volt pump is capable of inflating to 1.5 psi for a fast and easy inflation. For many inflatable crafts you'll still want to have a hand pump for top off to full pressure and to take along with you on the water.
• Comes with an adapter to fit a wide variety of valve types.
• Inlayed rubber insulates from heat and sound while providing a more secure grip.
• 12 foot power cord allows you to easily inflate your boat near your vehicle.
• There is a small hole in the pump nozzle. It's there to prevent back pressure buildup that can cause the pump to overheat.
• The electrical clamps allow quick and easy connection to your vehicle's battery.

Never operate LVM with vehicle motor running - can overheat pump due to a higher volt output.
