OutdoorMaster Shark 2S electric SUP air pump with 88.8Wh rechargeable battery (up to 20PSI, Type-C/12V input)

The essentials

If you regularly inflate SUPs (and other air-filled kit) on the beach, at the campsite, or even in the garden, a rechargeable electric paddle board pump can feel like a proper time-saver. The OutdoorMaster Shark 2S is a battery-powered SUP pump designed to inflate and deflate, with a digital display so you can keep an eye on pressure while it works.

On paper, the headline is the 88.8Wh rechargeable battery and the ability to inflate up to 6 SUP boards from a full charge. It also sets a maximum pressure of up to 20PSI, with auto-off once the target is reached. That auto shut-off matters more than it sounds if you want fewer “did I overdo it?” moments.

What it’s for (and what it realistically does)

This is primarily an electric SUP air pump that supports both inflation and deflation, built for quicker set-up and pack-down. The base information you’re working from suggests:

• Inflation and deflation time estimates are given for a typical SUP scenario: a 10.6FT paddle board to 15PSI in about 8 minutes 40 seconds, and deflation in about 1 minute 30 seconds.
• It’s rated up to 20PSI, so it’s aimed at inflatable boards and other inflatables that need a defined pressure.
• It’s also positioned for beach-away-from-the-car convenience, since the pump is rechargeable.

There’s also an “easy to pack away” angle here. A pump like this is usually chosen because manual pumps can be slow and tiring—especially if you’re setting up for family sessions or you’re helping others on the shore.

Key takeaways before you buy

The selling points are clear, but it’s still worth thinking about your own routine.

Where it shines

• Rechargeable battery + two charging options: It supports Type-C fast charging (45W) and also a 12V/15.8V DC input for when you’re near a vehicle.
• Auto-off at your target pressure: If you set a desired pressure (up to 20PSI), the pump should stop when it reaches the target, which helps reduce over-inflation risk.
• Real-time pressure monitoring: A digital display lets you watch pressure as it builds.
• Multiple nozzles: It includes 8 nozzles intended to fit a range of inflatables (the list given is broad).

The part that might disappoint

• The information provided doesn’t specify battery runtime per charge for all possible SUP sizes and pressures, only that it can inflate up to 6 SUP boards on a full charge. If your boards often sit at higher pressures, your mileage could be different.
• It’s described as compatible with many inflatables, but compatibility in practice depends on nozzle fit. The included nozzles should cover a lot, yet it’s still a “check the right nozzle for your valve” kind of purchase.

Using it in real life (quick micro-scenario)

Imagine you arrive at a beach car park, then walk down to where you’ll launch. Instead of hauling out a manual pump, you plug the pump in (Type-C or via vehicle if needed), then set your target pressure on the display. As it inflates, you can monitor the pressure changes in real time. Once it hits your target (up to 20PSI), auto-off should kick in, so you can step back without hovering.

When you’re done paddling, you switch to deflation. Based on the stated example, deflating a typical 10.6FT board scenario is quick enough to keep the “pack-up” phase from dragging.

Tech specs (from the details given)

• Battery capacity: 88.8Wh rechargeable battery
• Inflation capability: up to 20PSI
• Auto-off: turns off when target pressure/time is reached (prevents over-inflation)
• Inflation/deflation examples: inflates 10.6FT to 15PSI in ~8 min 40 sec, deflates in ~1 min 30 sec
• Charging inputs: Type-C fast charging (45W stated) and 12V/15.8V DC input
• Charging time (stated): fully charged in ~2H (Type-C)
• Display: digital pressure display
• Nozzles included: 8 nozzles

Who it suits (and who should look elsewhere)

It makes sense if you want an electric, rechargeable SUP pump for frequent use—especially if you don’t always want to rely on being next to a car. It’s also a good match for households or anyone who sets up multiple inflatables, because the “up to 6 SUP boards per full charge” claim suggests it’s built for more than one-off use.

It might not be a great match if your priority is maximum simplicity with minimal faff. Rechargeable pumps are convenient, but you do need to keep the battery topped up. Also, if you rarely use inflatables and you’re just inflating occasionally, you may prefer a more basic approach rather than managing charging schedules.

Is it a good fit if?

It’s a solid pick if you want faster inflation/deflation for SUPs, value auto-off safety, and prefer monitoring pressure on a digital screen.

It might not suit you if?

It may not suit you if you expect one nozzle to be perfect for every valve you own, or if you don’t want the extra step of maintaining a charged battery.

Mini FAQ

Does it inflate and deflate?

Yes. The pump is described as a 2-in-1 solution for inflation and deflation.

What’s the maximum pressure it supports?

It’s stated as up to 20PSI.

How do you charge it?

You can charge via Type-C fast charging (45W) and it also supports a 12V/15.8V DC input from a vehicle. The description also mentions it can act as an emergency power bank to charge a phone in urgent situations.

Are there enough nozzles for different inflatables?

The pack includes 8 nozzles and is described as compatible with a wide range of inflatables. You’ll still need to use the correct nozzle for your specific valve type.

Final verdict

Worth considering if you’re buying an electric SUP air pump for repeat sessions and you want less manual effort, clear pressure monitoring, and auto-off protection up to 20PSI. The 88.8Wh rechargeable battery plus Type-C and vehicle charging options make it feel practical for beach setups.

Should you buy it? It’s a sensible choice when you value convenience and don’t always want to be tethered to a car. Just keep in mind that battery performance will depend on how you inflate in your specific use (pressures and board size), and that nozzle fit is the key to smooth compatibility across different inflatables.
