Purchased to have with my vehicle in case of deflated tires when on the road. This little thing works great! I deflated my car tire to about 20 PSI and set this to 32 PSI as a test and it only took about a minute to air up my tire. Plus it isn’t even loud which is a nice bonus. Really easy to use and set up. Glad to have purchased this

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.

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.

Works great.

I attempted to pump up one of my car tires and literally stared at the screen for 5 minutes and NOTHING. The PSI reading never changed. I’ve used inflators before and bought this to just keep in my vehicle for when I needed it. Well, I needed it today and it let me down. I wish I didn’t buy this like 4 months ago because it would be an immediate return. I guess I’ll use it to pump up bike tires and basketballs since that appears to be the only thing this is good for.

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.

build quality is good, silent,for SUP, kayaks a bit slow, but if you use high flow mode first, and then switch to SUP, much faster, batteryis good, enough for 2 SUP in a raw

Compact , easy to use and much better than the other two my husband bought over the years . Takes no time at all to inflate a car’s tire.
