No one gets left out of the pump here
Absolutely high quality and functional SUP pump. The two 3.5 liter cylinders pump the SUP in stage 1 into the basic form within approx. 2 min. At level 2, the double stroke of the pump is deactivated and the system pumps 7 liters of air into the board each time the pump is depressed. In the last switching stage, only 3.5 liters of air are pumped with one cylinder. The air pump thus offers a fast and energy-saving inflation. This is faster than with any comparable electric pump. The pump comes in a handy, sturdy mesh bag. I am completely thrilled. From my side, I can only make a buy recommendation.
