The NRS is a double-action pump, so both the upward and downward strokes push air into your inflatable boat. You can also switch the NRS to a single-action pump.

The other technical features include a built-in water & oil separator for effective maintenance, manual safety valve for safety purposes, upgraded air filter for improved efficiency, and a full metal housing encased in anti-vibration rubber feet for portability.

The powerful 4000 mAh lithium-ion battery takes 8 hours to charge but is quite powerful. You can pump up more than one boat and do other things with the pump without worrying about the battery running out. The pump runs on 110 watts of power. Removable Nozze
