Air pump adapter set for SUP boards and inflatables Key benefits Fast, controlled inflation: use with a bike pump, compressor, or SUP electric pump adaptor to reach the recommended psi quickly and accurately. Reduces manual effort: start with a hand pump to preinflate, then finish with the adaptor to complete inflation without excessive pumping. Flexible compatibility: designed to work with standard fittings, enabling easy connection to bike/tire pumps, air compressors, or SUP electric pump adaptors. Clear, reliable inflation process: ensures you inflate to the correct pressure, improving board performance and safety. What you get Air pump adapter: for connecting a bike pump or compressor to inflate to the recommended psi. Air adapter: allows a SUP electric pump adaptor to utilize a standard fitting to couple with an air compressor or bike/tire pump. Pump adapter: recommended to use after hand inflating the board until it's difficult to pump further, then use this adapter to finish inflating to the pressure. How to use Connect any pump with a standard fitting to the corresponding adapter. Begin inflating the board by hand until it becomes difficult to continue. Attach the adapter and use your powered pump to finish inflating to the recommended psi. 2 3 practical use scenarios At the park or beach: bring a portable electric pump with the SUP pump adaptor to quickly reach the target pressure after a light manual preinflate. At home: use a bike pump with the adapter to gradually build pressure and then complete inflation to the specified psi with an electric pump if available. On a trip: carry the adapter set to maximize compatibility with available pumps (bike pump, portable air compressor, or SUP electric pump adaptor) and achieve the correct pressure with minimal effort. Compatibility and notes Works with standard fittings and connects to bike pumps, air compressors, and SUP electric pump adaptors. Intended to finish inflation to the recommended psi after initial manual preinflation.
