OutdoorMaster 20PSI High Pressure SUP Air Pump Shark - Intelligent Dual Stage Inflation & Auto-Off & Deflation, 12V DC Car Connector, for Inflatable Stand Up Paddle Boards, Boats

I’ve been paddleboarding for years, and the OutdoorMaster Shark SUP Air Pump has completely transformed my setup routine. This electric pump is fast, reliable, and packed with smart features that make inflating (and deflating) my board a total breeze. If you’re tired of sweating it out with a hand pump, this is the upgrade you need!Pros:• Lightning-Fast Inflation: The dual-stage system is a game-changer—350L/min for speed in the first stage and 70L/min for pressure in the second. My 11’ paddleboard hit 15 PSI in under 8 minutes, no effort required!• Intelligent Auto-Off: Set your desired PSI on the clear digital display, and it shuts off automatically when it’s done. No babysitting or worrying about over-inflation—perfect for multitasking while gearing up.• Deflation Made Easy: The deflation function is a lifesaver. It sucked all the air out of my board in about a minute, making packing up quick and compact. Rolling up my SUP has never been this effortless!• Built to Last: The active cooling system kept it from overheating even after inflating two boards back-to-back on a hot day. Plus, the 12V DC car connector with a 12A fuse feels safe and sturdy.• Versatile and Portable: It comes with a full set of nozzles that fit my SUP, kayak, and even an air mattress. Lightweight and compact, it tucks right into my paddleboard bag.Cons:• A Bit Noisy at High Pressure: The second stage gets loud, but it’s a small price to pay for the speed and convenience. I just pop in some earbuds if it bothers me.• Stiff Hose: The hose could be more flexible—it twists a bit during use, which can loosen the connection if you’re not careful. A quick adjustment fixes it, though.• Cord Length Could Be Longer: The 12V cable reaches my board from the car just fine, but if you park farther away, you might need an extension or a portable power source.This pump is hands-down one of the best investments I’ve made for paddleboarding. It saves time, energy, and hassle, letting me focus on enjoying the water. The OutdoorMaster Shark is worth every penny—five stars without a doubt!

I got this to inflate and deflate my Sea Eagle sts10 inflatable boat and it works REALLY well. I'm impressed with how fast it is.

I ordered 3 pumps to try with my Advanced Elements inflatable kayak. This is the one I kept. It's not perfect but it is a very workable solution. These kayaks only require 2 psi for the primary chamber but they have a proprietary spring valve that requires either a special adapter or enough pressure to keep the valve open during inflation so that the device can measure back pressure. The AE kayaks come with a hand pump that is very short and exhausting to use. It's annoying that NONE of the electric pumps offer the proper adapter to match the advanced elements kayaks that use this spring valve. This is a major manufacturer of kayaks so this adapter is really needed.Of the three I tried, this one was clearly the best. Plenty of pressure to hold the value open and get a live pressure reading. It stayed in first stage for most of the inflation. It managed to inflate my kayak all the way to 2.0 PSI in about 3 minutes - compared to an exhausting 10-15 min by hand. Unlike other solutions, I did not need to top it off by hand. This took me right to 2.0 PSI and shut itself off. Since I was able to do this with the valve in the inflate position no pressure was lost when disconnecting. I've been looking for this for a long time.For other AE kayak owners, you have two options. You can use the press fit adapter (the same one that works on all the other valves on the kayak) - it stays in position pretty well and it will push the valve core down to inflate - ie you don't need to inflate with the valve turned to the deflate position. But I also found I was able to tape the AE spring valve adapter onto one of the other adapters that come with the pump. You can use either silicon tape or self-fusing electrical tape. It takes a lot of tape to get a solid connection and it probably won't hold forever - but by doing this I can actually screw the OEM adapter on and use this pump. Since I have two of these kayaks to inflate when we go out, this has made a huge difference.For the price, it ought to come with a case and I really hate the shape of this pump. It's hard to get a grip on the body because of the curve and it doesn't neatly fit into anything. Not sure whose idea it was to have this shape (the marketing department no doubt). However, if you have an Adv Elements kayak with the spring valve - this is the one to get.

Awesome pump! I ordered this to pump my pull tubes up fast! I like pumping them up with some air pressure to, they glide on the water better and ride smoother with some air pressure behind them. All the other towable pumps are slow and weak, this thing pumped my big marble up in 3:30 mins! And 1-2 psi was more than enough stiffness for what we needed! Awesome pump!

This pump works so much better than my previous pump from a different company. It is an easy set up. It’s working great so far! I haven’t had it very long. Pumps to 15psi in about 8 minutes.
