OutdoorMaster Shark 2 High Pressure SUP Pump, Electric Air Pump 20 PSI | Auto Cooling & Auto-Off, Dual Stage Inflation, Digital Display, 12V DC, For Inflatable Paddle Board, Water Sports

I love this compressor. It inflated my inflatable kayak in less than 2 minutes, and it had no problem reaching the correct pressure. I paired it with my portable Duralast jump starter using the 12V outlet, and together they worked perfectly without needing my vehicle. It's powerful enough to inflate both my kayak and my paddle board quickly, saving a lot of time and effort compared to using a manual pump. If you own inflatable water gear, this pump is definitely worth the money. It's fast, convenient, and has made every trip to the water much easier.

I brought the pump in spring to use on my Stand Up Paddle Board (SUP) which inflates to 20 psi. The pump has worked perfectly all summer and super glad I brought it. Prior to buying the pump, I was using a manual pump the previous summer to inflate my SUP and it worked but took a lot of effort on my end to get to 20 psi. I have used it around a dozen times now and encountered no problems. On one of my outings I used it to inflate my SUP and two other SUPs (15 psi) and was able to pump all three SUPs consecutively. Some observations after using it all summer: - The pump does get a little hot when inflating to 20 psi. I did not notice it getting hot when inflating my friend's inflatable kayak (6 psi) or SUPs (15 psi). - The pump is loud; this is usually not a problem since I'm inflating my SUP in a parking lot and most parking lots are usually pretty loud anyways. - As others have stated, it does take around 10-12 minutes to get to the desired psi level. Not a big deal for me since I usually start the pump first and get my other equipment ready while my SUP is inflating. - My cigarette lighter is in my middle console and the power cord is long enough that I can use the pump on either side of my car. I usually try to park at an end spot so that I can have my SUP on a grass strip and not take up a second parking spot inflating my SUP. This also guarantees that I have a spot to deflate my SUP when I am done since someone could have parked next to me later on. - Love the fact that I can set the psi level and it inflates to the set psi level without having to consistently check on the pump. Also love that it remembers the psi level so I don't have to set it every time I use the pump. - Personally, I wouldn't use the pump on any equipment that requires pressure less than 8-10 psi since it probably would be quicker and easier to use a manual pump if you have one. Overall, I love the pump and would not hesitate to buy it again. Only time will tell if it will last but the build quality appears to be solid and I expect mine to last for many years.

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.

Works great. Just as good as the more expensive one I also bought to see the difference. This is a good one!

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 was so excited to use this electric pump. With all of the positive reviews saying it was the best, I figured I couldn't go wrong. Well...it does not work as advertised. It does not stay connected to my Hala paddle board after getting to about 1 psi. You have to hold the hose and connecter in place with a very firm grip to keep it attached to your board. The more the board inflates the more pressure you have to apply to keep the hose from losing air. Frankly if this was the only problem I could deal it. I don't need to walk away while my paddle board inflates to the proper PSI (what the advertisement shows). What I can't handle is that even while holding the hose and connecter nozzle in place, air starts randomly coming out of the hose as the board continues to inflate and I lose 1-2 PSI in an instant according to the pump gauge. I have to jiggle the hose and connector nozzle until it arrives at some magical position and stops losing air......for about 30 seconds and then it starts losing air again so I have to jiggle and move the hose again, and again, and again. All the while keeping very firm pressure on the connection. I've used it 5 times and have only once been able to inflate up to 12 PSI (my board is recommended to be 15 - 18 PSI). All the other times it continued to lose air and I couldn't get it past 10 PSI. Each time I have used this electric pump it has taken about 15 minutes to get to the point of 10 - 12 PSI where it would no longer inflate without losing air. For all but about the first minute, I had to hold the connecter in place with heavy pressure and then adjust the grip and hose each time it started losing air/PSI. I tried all of the suggested fixes from the manufacturers website, i.e., adding another plastic ring, making sure I had the right nozzle, etc. None work. Like another reviewer, I waited too long to use it after my purchase to be within the return window. Very frustrating. I will be reaching out to the manufacturer in hopes of a resolution.

I own a 180square foot inflatable tent and it blew it up in about 8min, it’s a good quality pump and the auto stop feature is nice. Worth the money 💯

I spent more than a few hours researching all could about these inflators. I compared dozens of models. I needed an inflator for my 2 Stand Up Paddle Board (SUP) which inflate to 15psi each. I recently bought one off Amazon that stated having an Automatic shut off. Auto shut off was must for me. It also was a dual volume, as it had a High Volume (for Stand Up Paddle boards/Mattresses) and a low Volume inflator (for Tires). It was also a dual power 12v/120v. Seemed like a good deal to have the dual power and volume modes and Automatic shut off. However it could not inflate my SUP past 10psi and Only the tire inflator had Auto shut off, which should have been specified in the description but wasn't. I did receive a refund. I decided to get an inflator that is designed for a specific need such as High Volume low psi inflation. When I received The Outdoor Master Dual Stage Inflator and unpacked it. Right away I could tell this was a higher quality product than my previous purchase. Let me list off the Pros of the Outdoor Master Dual Stage inflator: nozzles are tethered all together and are high quality; the Nozzles / Connectors that connect to the SUP and the end of the hose that threads onto the inflator make for a very solid connection; interface is easy to use; setting Auto Shut off is easy; the Automatic Shut off is very accurate; the length of 12v power cord is sufficient for me to plug into the 12V cigarette lighter in my SuperDuty Truck and and inflate my board a few feet away with out feeling restricted. Let me preface this about the Cons. None of the Cons were an issue for me. But, if you are like me you want to make an informed purchase. Cons: does not come with a Carrying bag; Only operates from 12v Power source and does not have lithium rechargeable battery pack or a 120v power. A couple of extra notes: It will inflate my 2 Stand Up Paddle Boards to 15psi with ZERO issue. Takes about 6 to 7 minutes each board (see edit below). Disclaimer I never Ran a stop watch. I am making a close guesstimate on how long I took. To me they inflated quickly and we were in the water and Paddling in no time at all. These types of inflators are just plain Loud. I have owned a total of 4 different inflators andI have used a $5.00 and even a $200.00 inflator and all were very loud. The Outdoor Master Dual Stage Inflator by far is the most quiet out of all of them. I hope this review helps someone out there make an informed and wise purchase . I highly recommend this product. USA. (edit/update, I recently ran a stopwatch on the inflate time. approximately 8min 40 seconds per Stand up Paddle Board to 14.5 psi. I was pumping by hand so having this pump is an amazing benefit)

this pumped saved alot of energy pumping up my SUp, should've of got it earlier. Worked like a dream.

Pump works great. Had no issues pumping up our paddle boards to max psi. It takes forever with the hand pump , this only took a few minutes per board. Keep the car running when using the pump.

Easy to use. I love that I can set the PSI required and it stops when it reaches that number. The unit is loud, but no louder than any other electric pump I’ve used before. Took all of, if not even, 10mins to fill my SUP. Very pleased with my purchase.

Can’t fault it. Inflates a SUP in minutes with zero fuss. All you can ask for. A+ for mine.

I like tbis pump a lot. I have had it for a couple years now and it still works and there is no wear on it at all. I use it in all sorts of conditions such as bushes and rocks and have dropped it a couple times and it’s great. It takes a little while to get to 15 PSI but worth it over hand pumping.
