Without question, the worst part of an inflatable SUP is pumping it up by hand. You feel like you get a full workout in before you even start paddling. I love paddleboarding. I hate inflating paddleboards. The answer to this is an electric pump. The Outdoor Master Shark Electric Pump is the best SUP pump out there today. It is an absolute must have for any inflatable paddleboard or kayak owner. In this review, we’ll take a look at what makes the OutdoorMaster 20PSI High Pressure SUP Air Pump so great

OutdoorMaster is a California based company started by a bunch of outdoor enthusiasts. They recognized that to get good functional gear you had to pay premium brand prices. Cheap bargain gear frequently didn’t work and was a waste of money. They decided to create great functioning gear at an affordable price. They started with ski goggles which have proven to be one of the best performing goggles on the market. Now they have moved into inflatable SUPs with the great performing Shark ii inflatable SUP electric pump and Chasing Blue paddleboards.

The Shark can inflate paddleboards up to 20 PSI. This is enough for almost every paddleboard made. Most inflatable SUPs are designed for 12.5 to 15 PSI pressure.
Inflating Multiple Boards with Cooling System
The Shark ii pump is one of the few pumps that claims it can inflatable several paddleboards in a row. Most pumps out there now can pump 1 or maybe 2 boards before overheating. The Shark can pump up 3 to 4 boards. It does this by having an active cooling system that keeps the motors cool. The cooling fan continues to run after pumping has stopped to ensure the motors can cool. The pump also has a sand filter inside to keep it from getting clogged and overheating. It has a 12a fuse to prevent damage if it does manage to get clogged.
In the event it does overheat, it has a high temperature cutoff that will shut down the motors until they cool off. This means increased safety because you won’t burn out your pump or start a fire from overheating.
The pump has a very easy to use interface with a digital pressure gauge. It can display both PSI and Bar. It can inflate up to 20 PSI in 0.5 PSI increments. To use you set the Pressure with the +/- buttons and hit the power and let it go. It automatically shuts off when it reaches the desired pressure.
Fast inflation and deflation
It pumps fast thanks to a 2 stage pump. It has both a high volume pump and a high pressure pump. It automatically switches around 1 psi too high pressure inflation. This is about the air pressure I find I have to switch from 2 stage to 1 stage with a hand pump. I timed pumping my Chasing Blue Infinite 10’6″ board and it took 7 minutes and 31 seconds. It takes me just under 6 minutes to do it by hand if I am really going at it.
The pump is quiet during the low pressure stage. It gets louder during the high pressure stage which is most of the inflation time. Its loud enough that you can’t hear your car running but not tolerable to stand around and talk. The below video shows the pup inflating a board.
The pump has a deflation function as well as inflation. Move the hose to the deflate nozzle and it will suck the air out of your board.
10 foot cord
The pump has a long enough cord to let you get some distance away from your car. The cord is about 10 feet. This is long enough that your paddle board doesn’t have to be right under your car to reach. The hose is long enough that you don’t struggle to get the pump to sit on the SUP board or next to it. It’s long enough that you can set your paddle board on the grass next to your car and still reach.
It comes with a variety of valves that cover almost every paddleboard made. This includes an H3/Halkey-Roberts, Pinch, Boston, 805, and C7 valve. It also includes a few different thickness gaskets to make all these adapters work. A new feature of the Shark 2 is that the adapters are connected to the end of the inflation hose instead of in a separate bag. This way you don’t need to keep track of a little bag of parts with the pump.
You can use this electric air pump on more than just inflatable paddleboards and kayaks. It can be used for almost any inflatable boat, inflatable watercraft, towing tube, inflatable dinghy, or other high pressure inflatables.
How well does it work
What we liked
This is one of the best paddleboard accessories you can get. I am extremely pleased with it so far. It works and works well. Let’s talk about some of the best points of this paddle board pump.
Inflation times almost as fast as hand pumping. I have tried out the Shark 2 on a variety of boards now.
- Chasing Blue Infinite 10’6″ x 34″ board – 13 psi – 7 minutes and 31 seconds
- Coolwave 10’6″ x 32″ board – 14 psi – 8 minutes 40 seconds
- Red Paddle Co 12’6″ x 30″ Sport – 15 psi – 9 minutes 35 seconds
- Red Paddle Co 12’6″ x 30″ Sport – 20 psi – 13 minutes 1 second
I can beat most of these times with the included hand pumps by 1 to 2 minutes. It takes a lot of work, minimum breaks to rest, and you are exhausted by the time you are finished doing it.
Below is a table of the time it takes all the pumps we tested to inflate a 10’6″ All Around Board and a 12’6″ Touring Board
|Name||10’6 x 32.5″ x 6″ All Around Board to 14psi||12’6″ x 30″ x 6″ Touring Board to 15psi||12’6″ x 30″ Touring Board to 20psi|
|Double Action Hand Pump||7 minutes 53 seconds|
|Red Paddle Co Titan 2 Hand Pump||6 minutes 15 seconds||9 minutes 28 seconds|
|Outdoor Master Shark 2||8 minutes 40 seconds||9 minutes 35 seconds||13 minutes 1 seconds|
|Outdoor Master Whale||9 minutes 22 seconds||9 minutes 58 seconds|
|Outdoor Master Dolphin||9 minutes 57 seconds||12 minutes 15 seconds||16 minutes 30 seconds|
|iRocker Electric Pump||7 minutes 27 seconds||8 minutes 32 seconds||11 minutes 50 seconds|
|Nixy Ventus||8 minutes 28 seconds||11 minutes 15 seconds||14 minutes 34 seconds|
|11 minutes 32 seconds||13 minutes 49 seconds|
|8 minutes 12 seconds||9 minutes 27 seconds||14 minutes 20 seconds|
The pump is very straight forward and easy to use. It comes with instructions but most people could figure it out without them. After plugging it in, you press the +/- buttons to set the target pressure. After this, you push the power button to start it. Then it pumps until the desired psi is achieved and it stops. Nothing to it. It handles switching from low to high pressure on its own.
The cooling fan works very well. To test out the pump, I inflated my board to its max pressure (13psi), deflated it, and inflated it again. I did this 4 times in a row to see how hot the pump would get. The result is that it didn’t get warm. This has proven to be a very consistent cooling system. The inflate hose was a little warm but that is it. It didn’t feel warm anywhere on the pump housing. It was about an 85F day while I did this.
I have inflated my board twice several times in a row while setting things up, figuring out how to use the pump, and showing friends how the pump works. It’s never gotten warm yet.
I timed the inflation of my board. It went from zero pressure to 13 psi in 7 minutes and 31 seconds. It takes longer than I can do it by hand but only by a minute. I’m sure it will save time on a hot day when I need to take more breaks while pumping. The pump doesn’t need to rest when the pumping gets difficult. I’d rather use my energy enjoying my paddleboard, not pumping it up.
Deflating with the pump worked very well. You have to unscrew the hose and screw it into the deflate port. Turn it on and let it suck the air out. This made deflating quick and easy compared to sucking out air with a hand pump or rolling the board to squeeze the air out. You will notice a change of tone when the pressure hits zero and you start sucking a vacuum into your SUP. Turn off the pump and disconnect the hose at that point.
What could be improved
The inflate and deflate labeling on the pump are hard to read. I almost need to remove my glasses and hold the pump up to my face to read them. I’m sure I will remember which is which after a while. It wouldn’t hurt if they mold the labels in a little more pronounced way. This is my biggest irritation with this pump and it’s not really much of a problem.
The feet of the pump could stand to be a little larger. I found that it tips over while pumping when you set it on the paddle board. This doesn’t really affect anything as long as the vents don’t get blocked. There is enough stiffness in the inflation hose that it can turn the pump on its side. The pads on the bottom of the feet are working fine when the pump is on the board. I can see that if you put it on concrete or a rough surface it might wear them after a while.
The pump does not come with a carrying or storage bag. This would be a great addition. I have a canvas bag that is just about the right size I have been using. A nylon storage bag with a handle would be great for storing the pump and parts.
Tips for using the Outdoor Master Shark air pump
1 – Check for air leaks
Check that there are no air leaks at the adapters, the valve in the board, and the hose attachment to the pump. You should not feel air coming out of any of these points. If you feel air leaking something is loose.
On my first try using the pump I did not tighten the H3 valve tight enough onto the hose. I started inflating and the pumping rate slowed down a lot around 5 psi. I felt my hand around the inflation valve and could feel air coming out. I tightened up the valve and tried again and it pumped up to 13 psi with no problem.
I have tried up to 17psi with the pump. There should be a steady increase in the psi level the entire way to maximum pressure. I didn’t notice much drop off in rate from 2 psi onward. If your pressure stops increasing or goes very slow you may have a loose valve or hose.
2 – Attach the inflation hose to the board first
I find it works best to attach the valve to the paddleboard and then attach the hose to the pump. The hose is stiff and can flip the pump over. If you hook the hose to the pump first you will twist the hose getting the inflation valve attached. This may put enough twist in the house that it won’t let the pump rest on the board. Hook up the valve and then screw the hose onto the pump. The hose won’t be twisted and everything will sit nice.
3 – Check your hand pump valve and gasket to know what to use
It can be a little confusing to find the right valve and gasket combination. The easiest way to do this is to hold up the valve on your manual SUP air pump and find the matching valve and gasket. Don’t assume because you have an OutdoorMaster pump and an OutdoorMaster SUP that the gasket on the valve will be correct. It wasn’t on mine. I had to switch the gasket on the Halkey Roberts Valve to the thin gasket. It had the thickest gasket from the start.
