ETENWOLF S4 SUP Electric Air Pump

• Etenwolf S4 SUP Pump

The Etenwolf S4 is a high-performance electric high-pressure pump that lets you quickly inflate a SUP board, kayak, inflatable boat, or other inflatable equipment.

Thanks to its two-stage pumping system, it reaches pressures of up to 20 PSI and operates up to 4 times faster than standard solutions.

The automatic shut-off feature when the set pressure is reached, a display showing real-time parameters, and the ability to operate continuously without overheating make using the device convenient and hassle-free, whether at the beach or on camping trips.

• Two-stage pumping

An advanced two-stage system ensures high performance. In Turbo mode, the pump delivers air at a rate of up to 600 l/min in the range from 0 to 1 PSI, and then switches to the high-pressure stage with a rate of 70 l/min, reaching a maximum of 20 PSI.

This design significantly reduces the time needed to prepare equipment for use and maintains stable pressure throughout the entire pumping process.

• Automatic pressure control

An easy-to-read LCD display allows you to monitor the current pressure in real time.

Using the buttons, you can easily set the target value in PSI, BAR, or KPA.

Once the selected pressure level is reached, the device automatically stops operating, eliminating the risk of over-inflation.

• Inflation and Quick Deflation

The Etenwolf S4 offers not only an inflation function but also effective deflation.

This allows you to deflate your SUP board, air mattress, or tent more quickly after use, saving time and space during transport and storage.

Additionally, the built-in temperature protection system ensures safe and stable operation of the device.

• One pump for many inflatable accessories

The set includes 7 interchangeable nozzles, allowing the pump to accommodate various types of valves.

It works perfectly with SUP boards, kayaks, inflatable rafts, recreational boats, air mattresses, tents, and other products that need to be inflated.

It’s a practical solution for people who enjoy spending time on the water and outdoors.

• Convenient for travel

The device is powered by a 12 V DC car outlet, allowing you to use it virtually anywhere.

An ergonomic handle makes it easy to carry, and a cable storage compartment helps keep things tidy during transport.

Its compact design means the pump doesn’t take up much space in your car or luggage.

• Designed for heavy-duty use

The Etenwolf S4 is designed for continuous operation without overheating.

This allows the device to inflate several SUP boards or other inflatable accessories in succession—a feature that families, groups of friends, and those who use multiple recreational items will appreciate.
