Why pump by hand if you don't have to? Let the NRS Blast 12-Volt Inflator Pump do the heavy lifting for you. Designed for fast and easy inflation of rafts and inflatable crafts, its compact size and rugged durability ensure it will be a reliable tool for years to come. Key Features: Fast & Easy Inflation: This 12-volt electric pump is capable of inflating up to 2 psi quickly. (Note: For many inflatable crafts, you'll still want to keep a hand pump nearby to top off to full pressure.) Universal Valve Adapter: Comes with a versatile adapter designed to fit a wide variety of valve types. Durable & Secure Grip: Inlayed rubber insulation protects against heat and sound while giving you a secure hold. Convenient Reach: A 12-foot power cord allows you to easily inflate your boat right next to your vehicle. Battery Powered: Integrated heavy-duty electrical clamps allow for quick, easy connection directly to your vehicle's battery. Overheat Protection: A purposely designed small hole in the pump nozzle prevents back-pressure buildup to keep the motor running safely. Important Safety Notes: Never operate with the vehicle motor running. The higher voltage output from a running motor can cause the pump to overheat. Do not block the small hole in the pump nozzle. It is there to bleed off back-pressure; blocking it can cause the pump to overheat and burn out the motor. Limit continuous use to 20 minutes. Allow for proper cool-down time between uses to prevent overheating.
