![]() This pump is also easy to carry around and store given its carry handle and flatter, oval-like shape it could fit in the front or main zipper pocket of most iSUP bags. This may seem super nit-picky, but when all the valve pieces are connected, they get in the way screwing and unscrewing the valve, and when wrapping up the hose it’s just one of our pet peeves. Instead, the valve pieces all come separated in a bag within the Shark II box. ![]() We also liked that it came with 6 valve options that are not connected to the hose via a string-like piece of plastic. It features an automatic shut-off as well, so you can set your desired PSI using the digital display and walk away without worrying about running the motor too long or over-inflating your board. The addition of Outdoor Master’s patented shark cooling system allows us to pump up 3 boards in a row with no rest period.Īs for the specs, the Shark II can pump up to 20 PSI in about 12 minutes, and under our testing pumped up a typical 10’ board in just over 11 minutes. We have been able to use this pump for about a year and a half now without a hitch, and believe me, we put it through the wringer. The Outdoor Master Shark II Air Pump is going to hold its spot at the top of our list of best electric pumps. We love the Shark II and it has yet to give us anything we’d call a ‘con’ *Use code PUMP2023 at checkout to save 20% for our readers!

Outdoor Master Shark II SUP Electric Air Pump ![]() Outdoor Master Shark II Electric Air Pump.Best Electric Pumps for Inflatable Paddle Boards (iSUPs)- 2023 With that said, let’s get into our list of our top 4 recommended electric pumps to help you narrow down your selection and make the best choice to fit your needs. It saves your time and energy for your paddle, will deflate your board to make for an easy pack up, and will overall help you have a better, more relaxing day on the water. They are lighter and easier to pack than a manual pump, and many can be made portable. Most electric SUP pumps are under $150 and are better than a manual pump in every single way. With that in mind, you’ll notice that this list is a bit shorter than some of the other best lists on this site but be assured that each of the 4 pumps below has been super reliable over the past year or so whether it be during our 110 degree summer days or inflating board after board on our testing days (bottom line- we’ve put these pumps through hell). We’re super picky about which pumps we suggest to you because about 50% of the pumps we get fail on us before year’s end, and we don’t want you to have that experience based on our recommendation. We also want you as our reader to be aware that we only add pumps to the best list that we’ve heavily tested for over a year. This is why an electric pump is our number one recommended accessory when it comes to building out your paddle kit. 15 minutes may seem like no big deal, but once you get your board past around 6 PSI, using the manual pump gets to be a decent workout.īecause of this, we see tons of people out on the water with half-inflated boards, not having as much fun as they could be. Depending on how strong you are, or how good your cardio is, it can take about 10-15 minutes to inflate. Operate adapter with no load powered by 12V and with meter is series with the battery leads so you can measure current.Most iSUPs come equipped with a manual pump in the kit. (You may want to start on a higher current range to protect the meter from violence or stupidity. ![]() ![]() Using a 12V power supply or a car battery and a multimeter with mA ranges. You can easily test the quiescent current draw. Most adapters will be active switching regulator types. This can draw no current at all when there is no load, but the output varies badly with load and it wastes more energy that it outputs. as you start a car far more frequently than that it should not be a problem.Ī low quality adaptor may use a zener diode dropper - I've seen it done. So even if you left that connected for a year it would probably take not more than about 1/2 of the battery's capacity. That's about 2 to 5% of a typical car batteries maximum capacity. Strangely - a poor quality adapter MAY draw none.Ī good quality adapter will use a switching regulator to step the voltage down - probably a "buck regulator" The quiescent (no load) current draw will vary depending on the design but I'd guesstimate it could be as low as 10's of microamps and would hopefully not be more than say 5 mA.Ī load of 5 mA will take 200 hours or about 8 days to drain 1 Ah from the battery. A good quality adapter will probably draw some current - but not much. ![]()
