Portable Electric Air Pump for Inflatables

The STIFFOUR air pump comes with several noteworthy features. Firstly, if the air pump fails to operate after pressing the On/Off button, and the indicator light flashes for 5 seconds before turning off, this indicates that the air pump is in battery saver mode and requires charging before it can function properly. Secondly, if the indicator light flashes while the air pump is operating, this signifies that the battery level is around 20 percent, meaning the pump needs to be charged as soon as possible. Thirdly, if the indicator light turns on after pressing the On/Off button but the machine does not function correctly, users should inspect the fan blade of the inflation vent for any obstacles or foreign objects.

Regarding safety precautions, users should not place their hands into the inflation vent or the air exhaustion vent. Additionally, it is crucial to ensure that no obstacles block the inflation vent and the air exhaustion vent. To prevent foreign objects from being blown into the eyes, the inflation vent or the air exhaustion vent should not be placed in close proximity to the eyes. Children under 12 years old must operate this product under adult supervision. This product can only withstand a minimal amount of liquid, so it should not be soaked in water or left out in the rain.

The STIFFOUR air pump boasts impressive inflation speeds, taking only 15 seconds to inflate a swimming ring, 45 seconds to inflate an air mattress, and 3 minutes to fill an inflatable boat. The air pump can be charged directly from a socket, power bank, car, or laptop.

The air pump offers two gear modes. In the first gear mode, long-pressing the air pump opening key for 2 seconds activates wind gear 1, and a short press switches to wind gear 2. The first gear is an automatic mode, where the air pump will automatically upgrade to the maximum power mode after reaching the predetermined pressure, and it will automatically shut down after continuous work for 5 minutes. If the inflation is not completed, users can long-press again to restart.

In the second gear mode, pressing the open key again while the air pump is working will enter the 2-gear mode. In this mode, the air pump will operate at maximum power. After continuous work for 5 minutes, it will automatically shut down to protect the air pump motor system.

The STIFFOUR air pump boasts impressive performance, with a professional electric air pump, a wind speed of 300L/min, a maximum power of 12W, and a pressure of up to 4000 Pa. The full-power operation can last up to 35 minutes, and users can activate the air pump by pressing and holding for two seconds.

The air pump comes with 4 different air nozzles that can be used for a variety of inflatable items, such as air cushions, swimming pools, sofas, water beds, boats, pool toys, and swimming rings. It can also be used for camping bonfire blowing, but it cannot reach a vacuum state for storage bags.

The portable electric air pump is compact, measuring only 2.1 * 2.5 * 3.2 inches and weighing 0.32 pounds, making it about half the size of a cell phone. The rechargeable electric pump saves storage space, and the included storage bag can hold the air nozzles and USB cable, allowing the mini air pump to take up a small amount of space for easy transportation. This air pump is an essential tool for quick and easy inflation and deflation, outperforming most manual pumps on the market.

However, it is important to note that this portable air pump is not suitable for use with yoga balls, basketballs, footballs, tires, balloons, or super-large water toys.
