Inflatable Boat SUP Pump Adaptor Standard Schrader Conventional Air Pump Air Valve Adapter Spoke Plate Attachment

Did its job without any problems. I more than likely will never have to replace them.

It doesn't feel real heavy-duty, but it allows me to inflate my ISUP (inflatable stand up paddleboard) using a battery-operated pump that has a schrader valve. I'll keep my fingers crossed that it lasts for a while. So far, I think it's definitely worth the price.

Not sure what the problem is but can’t inflate my wife’s SUP with this. I’ve tried it 3 times with my Ryobi battery operated inflator and have given up each time after 15 minutes and no visible form to the board. The manual pump gives shape to the board in a minute or less. I wonder if because the manual pump has a high volume and low volume setting, requiring high volume until the board takes shape then switching to low volume until desired PSI is reached, that perhaps I should use the manual pump on high first then switch to this. Haven’t tried it yet though.Update: I am bumping to 5 stars because it does work with my battery-operated inflator, just takes about 20 minutes to reach 15psi. Not a problem with the product, just normal time I guess. Beats the hell out of using the manual pump.

One worked on my ISUP. Not sure what I’ll do with the other that does not fit my board.

Worked great!

This adapter didn’t work and we had to use our old pump to inflate our SUP on our last trip. I was really hopeful this would make inflating our SUP easier. Item will be returned

It works great! Many reviews claimed the product didn’t work since the SUP that was being inflated was taking forever to inflate. It is not the fault of the device but the amount of or lack there of air pressure coming from the pump that is being used.The device creates a tight seal when being filled and is sturdy plastic.

These don't work EXACTLY as advertised. It did not work for MY intention so I will save you the trouble if you are thinking the same. long story short, it's for when you need to know the accurate PSI with real gage.I was trying to not spend 80 bucks on a 12v dual stage electric pump. I aired up my paddle board with a regular air mattress pump and it did the bulk of the work. then I put this on and started my 12v car tire pump. There is just too much volume left for the car tire pump. It would take too much time and the car tire pump would probably burn up from running that long. So can you pump your board up to 20 PSI with this? Probably, but you would need an 80 pump! OR, a regular air compressor at your house is a different story, but the main point is to take them too the beach deflated.Some people noticed there's leaking a bit. Mine sometimes does, but I just tighten it up more and its fine. Additionally, if I'm checking the PSI its entirely negligible. More air comes out when you don't get the air gage on there properly than from the fitting seals. So just pop it on, check the pressure, take it off. No big deal.

We have a cabin at the lake and wanted a way to pump up our paddleboards without using the hand pump. Standard high volume inflators can't pump up the board to 15PSI. We've tried about a dozen mini electic SUP pumps but most of them run on 12V and are underpowered, expensive and cheaply made.This HEYTUR SUP Pump adapter is the perfect solution for anyone who has an SUP, electricity, an air compressor and an air pressure gauge. This HEYTUR adapter snaps onto your paddle board converting your SUP air valve into a Schrader valve or car tire valve in layman's terms. You then attach your compressor to the value and pump up your SUP just like inflating a tire. I have an inline air pressure gauge and trigger chuck combination so I can check the air pressure as I'm filling up the SUP. It works awesome and is so much more convenient that hand pumps, mini compressor pumps, 12V car pumps or cordless pumps that need to have their battery charged.This HEYTUR adapter is inexpensive, simple to use and works. I bought the 2 pack for less than $15. If you have an air compressor this is the only way to go .... Highly Recommend!

works perfect

Man ska se till att alla delar skruvat in ordentligt.

Really useful for quick inflation (I combine electric pump with hand pump) but the little crossbar in the valve that the pump twists onto snapped after 4-5 uses. I have returned it and replaced with another in the hope it doesn’t happen again because it is so useful.

They fit perfectly with the Amor Aqua and Serene Life Free Flow iSUPs. Using them with electric tire pump is very slow, so I use the manual pumps that come with the iSUP to inflate to 8 or 9 PSI first and let the electric pump do the rest.
