Shark 3 for quicker inflation
The Outdoor Master Shark 3 is the pump we reach for when speed matters. In our testing, it inflated an 11’6” touring board to 18 PSI in 5 minutes and 18 seconds using its internal battery.
That’s a useful saving when you have another board waiting. It does come with compromises, though: it’s another substantial piece of kit to carry, and it certainly isn’t silent. For us, it earns its place by making setup quicker and letting us inflate away from the car.
Our Shark 3 review covers the inflation tests, charging, noise and the things we’ve noticed through regular use.
Shark 2S for longer between charges
The Outdoor Master Shark 2S is worth considering if battery life matters more than getting inflated as quickly as possible. Its 88.8Wh battery is larger than the Shark 3’s 74Wh battery, and we’ve found the extra endurance useful when spending a few days away from charging.
The trade-off is speed. Our 11’6” touring board took 9 minutes and 48 seconds to reach 18 PSI with the Shark 2S. We’re happy to accept the longer wait when we need more use between charges, but for a straightforward day’s paddle we tend to favour the quicker Shark 3.
You can read about those differences in our Shark 2S review.
Vortex Pro for a compact setup
If packing space is a priority, take a look at the Outdoor Master Vortex Pro. It offers rechargeable inflation in a compact format and comes with a storage pouch to keep the pump and accessories together.
Consider how far you’ll carry it, the boards you need to inflate and the space available in your kit bag. Compact doesn’t mean weightless, so it’s worth checking the dimensions and weight alongside the other specifications.
What our testing means for your board
The times we share come from boards we’ve actually inflated. A smaller board at 15 PSI won’t place the same demands on a pump as a larger touring board at 20 PSI. Board volume, target pressure and operating conditions all affect inflation time and the number of boards you can manage on a charge.
That’s why our reviews include the conditions behind the results, along with practical observations about charging, carrying and using the pumps. We also explain the drawbacks—because they matter when you’re deciding what to buy.
