Sharing is caring!

Updated April 9th, 2024

SereneLife SLPUMP10 Review

The worst part about using an inflatable paddle board is inflating it. Cheap paddle boards come with hand pumps that barely work and make you feel exhausted. An electric pump is the answer to making inflatable paddleboards much more enjoyable. The Serenelife SLPUMP10 is a simple low cost pump that can inflate boards up to 16 psi. We got one to try out. Keep reading to get the full review and test of the Serenelife SLPUMP10 electric paddle board pump.

What we liked:

  • Cheap electric pump that works
  • Small and compact. Easily fits in SUP bags
  • Easy to use controls and digital display

What we didn’t like:

  • Can’t deflate boards
  • Slower inflation times than other pumps
  • Questionable warranty and customer service

Features of the Serenlife SLPUMP10 electric pump

The Serenelife SLPUMP10 is one of the most popular inflatable paddleboard pumps on Amazon. It is also one of the cheapest. It is a single stage air compressor style pump with a max pressure of 16 psi. This pump is sold under many different brand names such as the Seamax SUP20S. Bodyglove includes this pump with several of their boards. Tuomico and Dongyan are 2 other popular sellers.

These small cheap single stage pumps are good to go along with cheap inflatable paddleboards. If you spent $200-$300 on an inflatable SUP paddle board, you probably don’t want to spend another $150 for an electric pump. You will hate life using the single action hand pump that came with the board and want a better solution. Little electric pumps like this and the Outdoor Master Dolphin are perfect options to go along with cheap inflatable paddle boards.

We paid for our own pump to try out for this review. We will give you all the positive and negatives of it like any other review we publish.

See our review of the Serenelife SLPUMP30 for their faster 2 stage pump that can also deflate.

The Serenlife SLPUMP10 electric air pump runs $56.89 on Amazon. You can expect to pay between $50 and $70 for it if you shop around for the cheapest seller.

The general rule of Amazon cheap items applies. If the item looks exactly the same, it probably is exactly the same, so browse around and purchase from the cheapest seller.


Serenelife mentions a 1 year warranty in the questions section for this item. A check of the comments and ratings reveals people have not had any luck getting warranty replacements. Assume when you buy this item that it does not have a warranty.

Size and weight

This Serenelife SUP pump has a compact portable design. It is 9.1″ x 5.5″ x 4.7″ in size. It weighs about 3 lbs. It is smaller than most 2 stage pumps. It will easily fit inside your inflatable paddleboad bag with the board.

12 volt power

This pump uses a standard 12 volt plug that will work with most 12 volt outlets in a car, truck or SUV. It has a 10 foot cord. It does not come with alligator clips or any other kind of adapter.

Stand Up Paddle board and Pool Toys compatibility

The Serenelife electric pump has a detachable air hose with a set of connectors on one end. A variety of rubber gaskets are included so you can put the correct thickness on any of the air valves.

It will work with almost any paddleboard or other inflatable water toy out there. It has the following valve adapters. H3/HR, C7, Boston, Pinch, and 805. This will cover almost every inflatable paddleboard, kayak, and water sports toys out there.

Max pressure

This pump has a max pressure of 16 psi. Target pressure can be set in 0.5 psi increments.

Inflate only

The Serenelife SLPUMP10 can only inflate boards. It does not have a deflate function.

1 Board at a time

The SLPUMP10 is only designed to inflate 1 paddle board at a time. The manual states that the pump needs to cool down for 30 minutes after being used for 15 minutes. 15 minutes is enough to inflate almost any All Around or Touring Paddleboard to 16 psi. It is not enough to inflate a second board. The pump will shut down if it overheats. Running it until it overheats over and over will reduce its lifespan.

Digital Display and Controls

The pump has easy to use controls and a small digital display. The display shows the target pressure before you start the pump. After it’s running it shows the current pressure down to 0.01 psi. The display is easy to read outdoors in bright sunlight.

It has 4 buttons for controls. A + and – button for adjusting target pressure. A power button for starting and stopping the pump. A PSI/Bar button to change the units.

This is an intelligent DC electric pump. It will auto-shutoff when the set pressure is reached. I would still watch it while running. It should not overinflate your paddleboard unless you set the target pressure too high. It has a 16psi upper limit. Most inflatable paddleboards can handle at least 15 psi without risk of damage.

Using the pump

The pump is easy to operate. Plug it into the board. Plug the 12 volt cord into the 12 volt outlet in your car or truck. Select your desired pressure. Hit the power button to start it. The pump will automatically shut off when the target pressure is reached. Hit power then sit back and relax for a few minutes while you wait for a fully inflated paddle board.

This pump doesn’t have a high volume stage to quickly fill up the board before switching to air compressor mode. For the first 4-5 minutes it will seem like it is filling the board very slowly.

Inflation times

We timed how long it took this pump to inflate 2 boards. A 10’6″ All Around paddleboard and a 12’6″ touring board. We inflated the all around board to 14 psi and the touring board to 15psi. For pumps that are able to inflate to 20 psi we would also inflate the touring board to 20 psi. The Serenelife SLPUMP10 has a 16 psi upper limit.

It took the pump 11 minutes and 32 seconds to inflate the 10’6″ ALl Around board. This makes it the slowest pump we have tested. It was slower than the Outdoor Master Dolphin by almost 1.5 minutes. The Dolphin is another air compressor style pump with no high volume first stage.

It took the Serenelife SLPUMP10 13 minutes and 49 seconds to inflate the 12’6″ touring board. This was also about 1.5 minutes slower than the Outdoor Master Dolphin.

Pumps with a high volume 1st stage can inflate paddleboards a few minutes faster. They are worth the extra cost if you care about how long it takes to inflate or want to also be able to deflate your board.

See the table below for the inflation times of all the pumps we have tested.

How many boards can it pump in a row?

The pump is not designed to inflate multiple boards in a row. It does not have active cooling like the Outdoor Master Shark 2 or Nixy Ventus pumps. It will inflate a second board with a rest to cool down between boards. We waited about 20 minutes between inflating the 10’6″ All Around board and the 12’6″ touring board. It was about 85F outside in direct sunlight.


Every inflatable paddleboard electric pump is noisy when running in the high pressure stage. This pump only operates in air compressor mode so it is noisy all the time. This is the worst thing about every electric pump out there. I haven’t noticed any pump available to be louder or more quiet than any other once they start acting as an air compressor.

The Verdict

The Serenelife SLPUMP10 electric air pump is a great companion for your inflatable paddleboard. It is small and easily fits in an inflatable SUP bag. It doesn’t cost much so you won’t feel like you are spending more on a pump than your board. If you want to enjoy the ease and convenience of an electric air pump, give it a try.
