It works on the majority of inflatable stand up boards.

It is also suitable for boats and kayaks which also use the Halkey-Roberts valve for inflation.Use your compressor or tire pump to easily reach 20 PSI.Be very careful not to over inflate your board or craft, and check the board' s pressure frequently.The car tire inflator is a low-volume high-pressure pump,(10Litre/min up to 100PSI) but these SUP pumps are high- volume low-pressure ,It takes about 15 minutes to fill up with acar tire inflator It fits the standard Halkey Roberts (HR) valve, which most SUP have, but some cheaper SUP don' t have a HR valve, so beware.

When used with a car tire inflator, it definitely does work, but the cheapest inflators will be too slow, and you probably need an inflator that outputs at least 70 Litres/minute (2.5GPM).
