Electric 12V SUP pump, does the laborious pumping of the SUP board for you up to 20psi and also works with almost all other inflatable products. The Saimaa SUP electric 12v pump fills the board up to 20psi conveniently from the cigarette lighter of a car or boat or directly from the battery with pike jaws. To speed up the pumping, the SUP pump initially only uses the blowing function and when the resistance rises, it starts the compressor, which produces 20psi of pressure. You can adjust the automatic cut-off to the amount of PSI you want. The high-quality designed and durable 12v SUP pump also has a suction function (the hose is changed to the suction side), with which all pull toys, swimming mattresses and rubber boats can be conveniently emptied into a small space. Thanks to its convenient size, the sup pump is easy to carry. Compatible with the following valve types: Halkey Roberts (SUP boards, larger dinghies) Boston Valve (Pull toys, rubber boats) Lighting Valve (Pull Toys) ECO v
