I was surprised that this pump was able to inflate the Tesla Cybertruck's 35-inch tire from 36 psi to 50 psi within 5 minutes. It completed inflating 3 tires in 15 minutes without overheating, while another portable Fantik X9 took 13 minutes per tire. I originally purchased this to inflate the Cybertent (buying a separate valve adapter is required) and I thought that I might have to buy another stronger pump for airing down and airing up the truck tires for frequently going off-roading, but to my surprise, this pump was all I needed. The original unit had an error where it stopped showing the battery level indicator after plugging into the 12V cigarette lighter, so I contacted customer service for a warranty issue. They were a little slow to respond at first, but they finally did send a replacement. For that, I'm confident in highly recommending this pump after much field testing, and I know that the company stands behind its product after sale. I'm very happy with the purchase and am using it quite regularly. Warning: if you are using the cigarette lighter socket method, the output rating must be 120W max for it to work with inflating vehicle tires. Otherwise, a 60W max works when I use it to inflate the tent.

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.

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!

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

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.

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
