Today I’m talking about the OutdoorMaster Shark, my favorite electric SUP pump, and for a good reason. I will tell you what is so great about the OutdoorMaster Shark (besides the obvious design), tell you about the difference between this model and the Bluefin Electric SUP Pump (which I was testing at the same time) and I will let you know where you can purchase this model for the lowest price.
The OutdoorMaster Shark once started as a crowd-funded project on IndieGogo, but since then it has become very popular and is sold in many places. This review is about the OutdoorMaster Shark II.
The difference between the OutdoorMaster Shark I and II is a design update and the implementation of their frost active cooling system, which allows this electric pump to be used for 30 minutes in a row. As it takes about 10 minutes to inflate a board, you can inflate 3 boards in a row without having to take a break in between. A marvelous update for families and groups.

I took the OutdoorMaster Shark electric SUP pump out for a day on the water, together with the Bluefin Aura Fit as you will see on the pictures. I was very interested in seeing the performance of both the OutdoorMaster and the Bluefin Electric Pump, as these are two of the most popular electric SUP pumps on the market.
Before this I have used the Decathlon electric SUP pump, but to be honest I did not enjoy using it a lot. Electric SUP pumps generally make a lot of noise and only work near your car, so you still have to carry it from your car to the beach. Maybe this depends on the country, but in the Netherlands the parking usually is nowhere near the water itself.
I’d rather spend my time on the beach instead of standing next to my car for 10 minutes waiting for a board to inflate, but then again I am a bit impatient when it comes to these things. So can the OutdoorMaster Shark or the Bluefin Electric SUP Pump convince me to switch to an electric pump? We’ll see!

Let us start with the specs of the pump. What does it contain and what can it do?
| Maximum pressure | 20 PSI |
| Weight | 3.6 lbs / 1.63 kg |
| Size (L x W x H) | 11.9″ x 9.45″ x 4.84″ / 30.23 cm x 24 cm x 12.29 cm |
| Voltage | 12 V |
| Stage 1 | 350L/min (Maximum speed) |
| Stage 2 | 70L/min (Maximum pressure) |
| Nozzles | C7, H3, Round 17 mm, Cone 7.3 mm |
| Cord length | 9 ft (2.75 m) |
| Max. usage time | 30 minutes (continuously) |
| Warranty | 1 year |
So as you can see the OutdoorMaster Shark offers quite a lot for an electric SUP pump. 20 PSI makes sure that you have a good and stable SUP board, which usually requires about 15 PSI. As said I have taken the pump to inflate the Bluefin Aura Fit, which I have inflated up to 18 PSI.
In my video review below you can see exactly how the Shark II works and how quickly it inflates any board I attach it to. This is a comparison video between my favorite SUP pumps, so you’re in for a treat!
In the first stage, the pump inflates with 350 liters of air per minute to get the board inflated as quick as possible. In the second stage, the board is already inflated but needs to be pushed to the right air pressure. As this takes more power, the pump goes to using 70 liters of air per minute to get this remaining part done. (Spoiler: The second stage is noisy!)
Below you can see a video of the OutdoorMaster Shark II in action, inflating the Bluefin Aura Fit SUP Board to 18 PSI. As you can see it takes about 10 minutes to fully inflate the board to the desired pressure and you can hear the noise you can expect from the pump while it is working.

So I have taken the OutdoorMaster Shark Pump out to the lake on a sunny day (it is a hot summer here!). I have unpacked the SUP board, the pump, and the accessories needed. Attaching the 12 V connector to the car is of course a piece of cake π°, as was attaching the nozzle to the valve of the SUP board.
You just turn on the pump, select the exact PSI (or bar if you wish so) on the digital screen and the OutdoorMaster Shark is ready to go. It is possible to set it by every 0.5 PSI to accurately inflate your inflatable paddleboard to the desired pressure. You do not have to be afraid that it will overinflate your board, as the pump will automatically switch off when the desired pressure is reached.
The pump is very accurate in measuring the pressure, where other pumps usually are a bit off on this. OutdoorMaster claims it is even accurate up to 0.01 PSI, which is hard for me to verify as I do not have the professional equipment with me to do this, but it seems very close at least.
As seen in the video the inflation took about 10 minutes, time I could spend sending emails and taking pictures around, or of course time you could spend together talking. If you inflate 3 boards in a row you will be next to your car for 30 minutes, so you might want to take some drinks if it is a hot day!

So the OutdoorMaster Shark has an on/off button, a button to switch between the pressure in PSI and bar and a + and a – button to increase the pressure by 0.5 PSI or decrease it by 0.5 PSI. If you need more explanation on how the buttons work, you should probably not be touching electric devices in the first place π€£.
The deflation option on the OutdoorMaster Shark is also very convenient, as getting the air out of your paddle board manually by rolling it up takes some time and effort and I would rather relax a bit after my paddling adventures.
A small downside of the deflating option is that it does not automatically switch off, it keeps sucking the air out of the board endlessly. When you see it is empty enough to roll up the board and stow it away just switch of the pump and move on with packing your stuff.
Deflation of the board with the deflation nozzle of the OutdoorMaster is logically a lot quicker than the 10 minutes of inflation time. Deflating the Bluefin Aura Fit board took me 3.5 minutes, which is faster than I would do it. On the other hand I can inflate this board manually in 5 minutes, so an electric SUP pump cannot beat me at everything πͺπ».

As said I will also compare the OutdoorMaster Shark to the Bluefin Electric Pump. They are in the same price range (with the OutdoorMaster being a bit more expensive) and both offer to inflate your board quickly. As you can see on the pictures above, the OutdoorMaster Shark is a lot bigger than the Bluefin Electric Pump, almost twice the size.
So which of the two pumps is better? The short answer: the OutdoorMaster Shark. They both offer a lot of similar functions, like the digital pressure meter, the automatic shut off at the correct pressure, 12 V car adapter and an easy connection to the SUP board.
But the main thing you want from an electric pump is quick inflation. The OutdoorMaster shark took 10 minutes to inflate the board to 18 PSI, the Bluefin Electric Pump took 14 minutes to inflate the very same board to 16 PSI. So it took 40% more time to inflate the same board to a lower pressure, which is too much and makes the OutdoorMaster win this comparison easily.

Another difference is that the OutdoorMaster Shark can inflate a board up to 20 PSI, where 16 PSI is the absolute maximum for the Bluefin Electric Pump. The OutdoorMaster of course has the very handy deflation option, that the Bluefin Electric Pump is not equipped with.
Also the Bluefin Pump does not have all the nozzles that the OutdoorMaster Shark comes with, so for instance an inflatable air mattress would not be possible to inflate with the Bluefin version. Last but not least the Bluefin Pump got pretty hot after using it on one board and it made a lot more noise than the OutdoorMaster Shark.

The only advantages of the Bluefin Electric Pump are the smaller size, easier carrying and the lighted display. (For all those times I go paddle boarding in the dark…). If you want an electric SUP pump that does what it should and as quickly as possible, always go for the OutdoorMaster Shark!
So I think the conclusion of the comparison between these two pumps is very clear, the OutdoorMaster Shark wins it by miles. To be fair it isn’t even really a contest, these pumps are in completely different leagues.

The OutdoorMaster Shark is suitable for everyone who wants to go out with an inflatable paddle board and does so by car. Remember: this electric pump does not work on a battery but only with a direct connection to the car, so if you are going by bicycle or maybe through public transport a manual pump will be the only option for you.
But it doesn’t matter if you want to inflate one paddle board or up to three, because of the built in cooling system the pump can keep inflating all three boards without having to pause in between. So no matter if you go alone or in a group, this electric SUP pump is meant for you.
You will however have to be willing to stay near the car for the duration of the inflation (I’m a poet
