Inflatable Boat SUP Pump Adaptor Air Pump Converter Standard Schrader Conventional Pump Adaptor Air Valve Adapter Pumping Head Connector for Inflatable Rowing Boat,Stand Up Paddle Board,Kayak

This works perfect for my blow up pontoon fishing tube. Great quality.

Not sure if the connections are incorrect inside the valve or if I just don't have enough surface to tighten the valve but never could get it to latch. Once the connector is inside the valve I was unable to twist with my fingers or with pliers. Seems like structure is solid just couldn't use it. Worked fine with the new Bluefin iSUPs.

Required lubricant. Once lubrication was applied, no issue with fitting properly and worked like a charm. No longer at muscle failure before I head out. Recommend that paperwork be included that provides recommendations and solutions when the adapter doesn’t connect properly.

This is it! The solution I was looking for. I'm now able to fill up my paddle boards using my Ryobi 18v dual flow air compressor. I start with the high flow side, which gets the paddle board up to around 3 PSI. Then I attach this Schrader converter, set the pressure to 16PSI, and flip the switch.Now...I'm not going to tell you this process is fast. It isn't. With my paddle board, we're talking 15-20 minutes to get it to the appropriate pressure. But it save you the back-breaking effort of using a manual pump, and for that reason it's well worth it.

I bought this in lieu of buying a specialized SUP compressor pump...but unlike the special compressors, this really is intended only for the last few PSI, and not the full fill. I experimented and tried a from zero to 5 PSI run, and gave up at around 25 minutes. It was inflating, but soooo slowly. in that period of time it did not reach any registerable PSI. My friend's SUP compressor pump takes roughly the same amount of time of a full manual pump up..about 10-12 minutes. So I wish I had paid more attention, that this is just for topping off, really. If it doesn't work like the SUP compressor, then it's not worth it to me to lug my standard compressor around in addition to the manual pump. I'll just develop really strong tri's. It works as advertised, just be sure you read what they advertised.

The second one I bought would not lock in place and I couldn’t inflate my paddle board. The one I bought a year ago worked great but I misplaced it. I don’t know what the difference is.

I bought this to use with my Caribe' Rigid Bottom inflatable. It works great, exactly as advertised. I am using this with my commercial duty air compressor to maintain the inflation of my boat. Although high pressure air compressors are low in volume, this works great for me. Much easier than the low pressure, high volume, foot air pump although it takes a bit longer but zero effort.

This adapter appears to be quality made, with a solid design. I couldn't be happier with my purchase.I used it to inflate my DDM Inflatable paddleboard (SUP), equipped with the Halkey-Roberts style valve. With my little Ryobi compressor, it took me about 23 minutes to pressurize my 10' by 6" by 30" board to 13 PSI from a full, but non-pressurized state.
