Yes — the OutdoorMaster Shark 2S is worth buying if you want a rechargeable SUP pump that can take you away from the car, and the current £139.99 price makes it more attractive than usual. It sits at 4.3/5 from 578 reviews, is 13% off the £159.99 RRP, and the current price is the all-time lowest recorded, so this is a strong buying window rather than a rushed premium purchase.

What stands out first?

The headline feature is the 88.8Wh rechargeable battery, which OutdoorMaster says can inflate and deflate up to 6 SUP boards on a full charge. That matters in real UK use: if you’re rigging up at a windy car park, a lakeside launch, or a beach spot where mains power is nowhere near, a battery-powered pump removes a lot of faff. The Shark 2S also supports 12V/15.8V DC input and Type-C input, with 45W Type-C fast charging claimed to fully charge it in 2 hours.

How does it perform on the water?

OutdoorMaster claims the Shark 2S can inflate a 10.6ft SUP at 15PSI in 8 minutes 40 seconds and deflate it in 1 minute 30 seconds. Those are useful numbers because they point to a pump that is designed for practical pre-session setup rather than just emergency top-ups. The max pressure of 20PSI is also important: many recreational SUPs in the UK sit below that, but having headroom is reassuring if you use a firmer touring board or want precise final pressure before heading out on flat water.

The auto-off function is another genuine benefit. You can set a target pressure or inflating time and the pump shuts off when it reaches the chosen setting. That reduces the risk of overinflation and makes the Shark 2S easier to trust when you’re distracted by kit, wind, or changing conditions.

Is the 2-in-1 inflation and deflation useful?

Yes — especially if you want to pack down quickly after a session. OutdoorMaster says deflation takes 1 minute 30 seconds for that same 10.6ft board, which should make post-session pack-up much easier. That is particularly handy on cold, wet days when you want to get off the beach or slipway fast, or when you’re folding multiple inflatables after a family outing.

What about build and versatility?

The Shark 2S includes 8 nozzles and is listed as compatible with stand up paddle boards, air beds, kayaks, kites, boats, arches, swimming inflatables and more. That wide nozzle set boosts value because it turns one pump into a multi-use accessory, not just a SUP-specific gadget. For households that mix paddling with camping or summer inflatables, that flexibility is a real plus.

Is it good value for money?

At £139.99, it is cheaper than its £155.07 average price by about 9.7%, and the price history is encouraging: the lowest ever recorded is £99.99 while the highest is £228.81 across 72 data points over roughly 72 weeks. That history suggests the current price is reasonable rather than inflated, and the all-time-low alert makes it a better buy now than it was at many other points in the past.

The main value question is competition. The nearby alternatives provided are not direct pump rivals: the Helly Hansen buoyancy aids are £41.49 each, and the Premium 35L waterproof dry bag backpack is £39.99. Those products are cheaper, but they solve different problems entirely. If you already own safety kit and storage, the Shark 2S is the item that saves time and effort at launch and pack-down; if you still need core paddling safety gear, those lower-priced accessories may deserve priority first.

Any drawbacks?

The biggest warning is that £139.99 is still a meaningful outlay for a pump, especially if you only paddle a few times a year. Also, the listing copy gives strong performance claims, but the data provided here does not include long-term durability, noise, or real-world battery degradation, so buyers should not assume it will feel premium in every respect just because the spec sheet is strong. Finally, the product rank of #8146 in category suggests it is not a mass-market best seller, so it may appeal more to committed paddlers than casual impulse buyers.

If you want a portable, battery-powered SUP pump with useful pressure headroom, auto shut-off, and multi-inflate versatility, the Shark 2S makes a convincing case. If you mainly launch beside the car and only need a pump occasionally, the price may feel harder to justify than a simpler mains-powered option.
