I bought this pump to inflate kayaks. I love that you can adjust the pressure and that it’s portable. It has come in very handy to inflate and deflate all sorts of stuff. I’m buying one for each of my children. Makes a great gift.

Can pump up my inflatable SUP to 15psi. Only small issue is that from a full charge, the pump only can get to 10-11psi via battery power. I would recommend just using it with the 12v attachment for the most part. Still an invaluable resource for SUPs as well as pumping up car tires if needed. It will take some time, but it’s better than the manual pump! And it allows for quick deflation when you are ready to pack up!

This has been a pleasant surprise. I have 6 large all-terrain tires on my Sprinter 3500XD van (235/85 r16) and I was able to get them all pumped up from a pretty low state in one charge. These devices are noisy in general so it was nice to be able to set a PSI and go back inside while it worked.

This product did not work on 12v car plugin. I tried it in my car and my partners, and it would not work. We used the neighbors blow up on our 12v and it worked. So we are returning product as it did not work as described and we don't feel its powerful enough.

I paddleboard. I have multiple paddleboard pumps. This pump always comes with me. It is my slowest pump. Why do I always take my slowest pump? It is the best pump I know of that has both a battery and can run off 12v DC power (from a car). I always want the security of knowing I can inflate and deflate my boards without having to worry about the battery health and capacity. To be honest; I usually bring two pumps (I’m always inflating/deflating multiple boards… I bring my fastest battery only pump as well). But that should not detract from this excellent device and how indispensable it is to me.

Edit: Adding a star because HOTO reached out to me after I initiated my return and apologized for the issues I had. They even sent me a new pump from one of their other models. Really excellent customer service, and that's worth an extra star. I still wish the "pump master" worked for me, but big props to HOTO for trying to make it right.Bought this (quite expensive) pump because it is one of the only ones I can find online with different tools for different uses that includes filling up a stand up paddleboard. I've got a pair of boards that fill to 15psi. But I liked that I could also use this on my tires for roadtrips, or other uses while camping. So I justified the really high price.Well, this little pump couldn't get through it's first use when I went out to go paddleboarding with it for the first time.I used a manual pump to quickly fill the board with a basic volume of air up to about 7psi and planned on using the Hoto pump just for the higher pressure air fill. So the Hoto didn't even need to fill the whole board. Well, unfortunately, it wasn't able to do that job. I plugged it in to the first board and it took a while to get from 7psi to 14psi, then it suddenly stopped and threw an error code. I attached my manual pump to finish it off to 15psi but my manual pump showed the Hoto pump had actually filled the board to 17psi!I like the intended functionality. It's a battery powered pump with a bunch of attachments, and you can't really find that elsewhere. I had hoped for the price it'd work for me and I'm disappointed it didn't. I ended up returning it for a refund and I'll just use my manual SUP pumps for now.
