Valve comes loose from pump

We have 3 of these pump, you need them of course to pump up the sup, do you can't have not one. All 3 of them have the same problem, the valve. Before buying ask information about this. Decathlon tell me they can't help me with in store purchases. So every time we want to use the sup, it is a struggle. Great service! Also telling my gender is ridiculous, reason why you need to tell gender :This information will be display. It helps to contextualize your review and makes it more useful. Odd

Works well, but not only for SUPs

Note this is the correct pump for the Itiwit X500 kayak, not the supposed "kayak" pump! It has a different connector and supports a higher pressure (up to 20 PSI) than for the other kayaks. Thanks very much to your store staff for swapping it and going to lengths to double check it was right. The pump is easy to use. As with other Itiwit products, it's clearly labelled on the pump that it has two modes, double pumping up to 5 PSI and single pump beyond that. It doesn't take long to pump up the kayak. The built in pressure gauge is great, much better than the separate one on the other models. As another reviewer mentioned, the hose does unscrew at higher pressures. I found I had to keep hold of the connector on the pump itself, hence 4/5 stars. The one on the kayak stayed perfectly.

Not suitable for all iSUP boards

I have given this only two stars as it does not work on my board.. Generally the pump seems well made and as with all Decathlon really good value!! But I purchased this as the pump supplied with my iSUP developed a fault and anyway I wanted something a bit lighter and less bulky when travelling by rail to reduce weight and create more space in the bag. However the hose connection to the valve in my iSUP does not lock into the valve, it just spins back out as soon as pressure is applied. So one hand would have to hold this in place. This makes pumping impossible or it becomes a two person activity. So I am returning it. I would recommend the pump but only if it had a universal connector to an iSUP valve


The paddle inflated in no time at all very good

The pump does the job BUT as soon as you get near to 10psi the corrugated tubing starts to unscrew from the pump, as a result this becomes a two person job to get to 15 psi one to keep the tube from unscrewing and one to actually inflate the SUP. Took it back to my local store to swap it thinking it was just a faulty pump but no more in stock (I have been Informed there has been some on order since last week) I have therefore kept the pump for now as we wanted it for holiday...will be refunding it upon return for a new one. Whilst in store another gentleman noted he had the same isssue with his, so it would appear it is not isolated to mine. Would be great if there was a really good larger capacity pump with interchangeable connectors as I also have an inflatable kayak so have to take two different pumps everywhere! Like I said it does the job but need two people which defeats the object!


working good, anyway capacity is too small it should have two tubes

Wrong pump

Bought this as it has the gauge and is same brand as the kayak I bought at double the price of others...turns out its the wrong pump for the kayak :(

Pump not labelled - take care to get the right one

I was sold this to pump a kayak - there are no labels on it stating purpose - when I got home and checked it online found it is a specialist pump for paddle boards. Two hour round trip to my nearest store

Great for 6 months but broken

This pump worked great for 6 months but the internal seal has broken on mine and now doesn’t work.

Gauge DOES work after all!

I note from the reviews below people like myself who assume the gauge doesn't work because they don't know that they have to keep pumping for a while until 3 - 4 psi. I returned one pump because I didn't know how much pumping is required. The simple solution is to add some instructions to the packaging - I only discovered the facts by looking online at your website

Sup pump

Easy to use excellent

Two times gauge doesn't work

The gauge doesn't work, returned the first one and got the same problem for the one I have just received from delivery. I haven't tried my iSUP itiwit yet because the gauge doesn't work to know correct pressure. I live 3 hours away from decathlon, so not ideal to get defected item.

Dear Debora,

Thank you for your feedback. We are sorry to hear that you discovered some issues with the SUP pump. We checked with the product manager and he advised that you have to reach 3-4 PSI before you will start to see the gauge working. At the beginning there is not enough pressure inside the SUP board and this is why it looks like there is something wrong with the gauge. Please try it once again. If you discover that there is no movement on the scale and the SUP board is like a solid block even if you stand on it then it will be clear sign that the pump has some defect.
Once again apologies for any inconvenience caused. We hope from now you will be able to enjoy your SUP boarding.
Kind regards, 

Will not fit my SUP connection?

I bought this pump, only to discover the valve fitting does not fit properly into my Vandal SUP!!! The fitting looks the universal shape but slightly too short to lock into the Vandal SUP valve...... wasted my money!!!

Dear Customer,

Thank you for your feedback. We are sorry to hear that you found our SUP pump not suitable for your Vandal SUP board. Unfortunately brand to brand may have a different standards and dimensions and we can not guaranty that our model will fit other brand equipment. Please return your item to the nearest store or use the online procedure for full refund.
One again apologies for any inconvenience caused. 
Kind regards,

Perfect for caravan air awning or airbeam tent

The pump that came with my Kampa Fiesta Air Pro awning was useless and the awning only just stayed up. This pump is absolutely fantastic, it's quick and pumps so 8psi which transforms the awning into a stable structure.
