Outdoor Master Dolphin Pump – Review and Field Test 2022

Outdoor master dolphin pump

The worst part about using an inflatable paddle board is inflating it. Cheap paddle boards come with hand pumps that barely work. Pumping up a board with a single action hand pump makes you exhausted before you even start paddling. An electric pump is the solution and one of the best SUP accessories you can buy. The Outdoor Master Dolphin electric SUP pump is a low cost, small, pump that can reliably inflate your board up to 20 psi. Keep reading to get the complete story on the Outdoor Master Dolphin pump.

About Outdoor Master

Outdoor Master 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 stand up paddle boarding with inflatable SUPs and electric SUP pumps.

We really like the electric SUP pumps by Outdoor Master. We have been using the Shark 2 and Whale for a while now and love them both. I rarely ever hand pump a paddle board since getting them. They are both pricey and not that small. The Outdoor Master Dolphin is a cheaper alternative that is small and lightweight. It is only 2 lbs and small enough to easily fit inside any inflatable paddle board bag. It can still inflate boards up to 20 psi.

What does the Dolphin give up? It does not have an internal cooling fan so it can’t pump up several boards in a row. It can’t deflate boards. It only has a single stage pump so it takes a few minutes longer to inflate a board.

Price

The Dolphin costs $79.99 on Outdoor Master’s website. With our discount code ERO15 you can drop the price to $68. The Dolphin is also available on Amazon. I have seen it on sale on Amazon for as low as $40 if your lucky.

Size and weight

I can easily hold the Dolphin SUP electric pump in the palm of my hand. It is 10.25 X 6.25 X 5 Inches. It weighs about 2 lbs. The Dolphin has a shorter air hose than the Shark and Whale Pumps to go along with the smaller size. The Dolphin easily fits into the bag along with your paddleboard and all the accessories. It doesn’t add too much weight either. It has a convenient carry handle attached to the top as well.

12 volt power

The pump has a 12 volt plug for use with the 12 volt outlet in your car. The power cable is about 10 feet long so you can get the pump close to your board. The plug has a built in 10 amp fuse. You can replace it by unscrewing the metal end of the 12 volt plug.

Stand Up Paddle board compatibility

The Dolphin will work with almost any paddleboard or other water sports inflatables out there. It has the following valve adapters. H3/HR, C7, Boston, Pinch and 805. This will cover almost every inflatable paddleboard and kayak out there. Most inflatable paddleboards use H3 or Halkey Roberts plugs which this pump has. It will work with any SereneLife, Funwater, DAMA, Coolwave, Outdoor Master/Chasing Blue, iRocker, Red Paddle Co, Starboard, and many others.

Max pressure

This pump can inflate up to 20 psi. Most paddleboards inflate to around 15psi so it gives you some extra power. It won’t struggle to get you to 15psi.

Inflate only

The Outdoor Maser Dolphin can only inflate paddle boards. It does not have a deflate port that the Shark and Whale have.

1 Board at a time

The manual included with the pump states that you should only run the pump for a maximum of 15 minutes. After that, it should cool for 30 minutes before being used again. This pump is not designed to inflate more than 1 board at a time. If you need that ability check out the Shark 2 or Whale which can inflate several boards in a row without overheating or damage.

Digital Display and Controls

The Dolphin has a digital display for real time pressure monitoring in either PSI or Bar. It has 4 button controls for easy operation. It has 2 buttons for setting pressure. 1 button for switching between PSI and Bar. 1 button for power/starting and stopping the pump. It’s very intuitive and easy to use. Just set the desired pressure and hit the power button. It will automatically stop when you reach the target pressure.

One complaint is that it’s not easy to read the display in bright sunlight. You will need to hold your hand over it to shade it enough to read what it says.

Using the pump

We have spent a lot of time with Outdoor Master electric paddle board pumps. They are all reliable and easy to use. The Dolphin is the smallest, lightest, and cheapest of the bunch. It uses a similar high pressure pump to inflate the boards. It does not have a high volume first stage so it takes a few minutes longer to inflate than the other boards.

Fast inflation time

We hooked up the pump to a Coolwave 10’6″ by 33″ paddle board. This is a typical $250-$300 paddleboard similar to those sold by Serenelife, DAMA, and Funwater. We inflated it to 14 psi. It took 9 minutes and 57seconds to inflate. For comparison. It takes the bigger Outdoor Master Shark 2 8 minutes and 40 seconds to inflate the same board to 14 psi.

It takes me 7 minutes and 53 seconds to inflate this board by hand using the supplied double action pump.

Inflating boards to 20 psi

We have a Red Paddle Co Sport 12’6″ x 30″ board that can be inflated to 20 psi. We hooked up the Dolphin to it to try out the 20 psi max pressure claim. The Dolphin had no trouble pumping it up to it’s 20 psi max pressure. It took 12 minutes and 15 seconds to pump this board up to 15 psi and 16 minutes and 30 seconds to get it to 20 psi.

Red Paddle Co boards come with the monstrous Titan 2 hand pump. Using the Titan 2 Pump, it took me 6 minutes and 15 seconds to inflate the board to 15 psi by hand. It took me 9 minutes and 28 seconds to get to 20 psi.

I inflated the same board with the Shark 2 also. It took 9 minutes and 35 seconds to get to 35 psi. It took 13 minutes and 1 second to get to 20 psi.

The Dolphin needs 1-3 minutes longer than a 2 stage pump such as the Outdoor Master Shark 2 to pump up most boards. It takes 2 to 6 minutes longer than hand pumping depending on the size of the board and target pressure. It saves a lot of work and you’re not exhausted before you even start paddling.

How many boards can it pump in a row?

The Dolphin pump is compact and small and not designed for pumping up several boards in a row. The instruction manual states that you should let it cool down for 30 minutes after working for 15 minutes. It does have an overheat protection circuit in it to prevent damage if you do overheat it trying to do too much.

Noise

The Dolphin has a similar noise level to every other electric paddle board pump I have heard. It operates 100% in a high pressure cycle which is the noisy part for every electric SUP pump. This is my biggest complaint about electric paddle board pumps in general. They are all noisy during their high pressure cycle. I tend to turn on the pump and then walk away for a while and check it every few minutes.

Tips for using the Whale Pump with your inflatable SUP

1 – check for air leaks

Even a small air leak around the air valve, adapter fitting or hose connection will make it impossible to get up to pressure. Feel for air leaks when you start the pump. You should see a steady increase in pressure once the pump goes into the high pressure cycle above 1 psi.

2 – attach the inflation hose to the board first

The air hose is stiff enough that it can untwist the valve out of the board if your not careful. I find it easier to hook the valve up to the board. Set the pump down on the board so that the hose is twisting the valve into the board. This will make sure the valve stays in place while pumping.

3 – use the correct gasket on the valve

Use the correct rubber gasket on the valve. This pump came with the correct thickness rubber gasket on the H3 valve. It works with all of my inflatable paddle boards correctly right out of the box. My other 2 Outdoor Master pumps had the wrong thickness gaskets on the H3 valves. Check to make sure the rubber washer is the same thickness as the one on the hand pump that came with your board.

4 – Save time using your hand pump up to 1 psi

Hand pumping doesn’t get awful until you get past 1 PSI and have to go down to single action. The Dolphin pump lacks the high volume pump stage that makes other pumps take about a minute to get to 1 psi and switch to high pressure mode.

If you want to speed up the process with the Dolphin you can assist with your hand pump. Hook your hand pump up to the board and pump it until you need to switch to single action. Hook up the Dolphin and skip the tedious high pressure hand pumping.
