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.

Nice design and additional perks such as a waterproof bag, but the battery is not enough powerful. It can’t properly inflate a paddle board, barely reaching 12 PSI before shutting down.

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.

Unfortunately the hose attachment for the SUP doesn’t work with this item. There isn’t an effective plug while pumping, so air leaks out and the entire process takes 30 minutes with the car turned on for battery power. Otherwise the battery only version runs out of juice when it’s half-filled. Disappointing; will have to buy new hose attachment from another company and hope it works.
