Portable Electric Air Pump for Swimming Ring, Pool Floats, and Air Bed

Troubleshooting/Warning: 1. If the air pump doesn't turn on after pressing the On/Off button and the indicator light flashes for 5 seconds before turning off, it means the air pump is in battery saver mode and needs to be charged before functioning properly. 2. If the indicator light flashes during operation, it indicates that the battery level is around 20 percent and the pump needs to be charged as soon as possible. 3. If the indicator light turns on after pressing the On/Off button but the machine doesn't function properly, check the fan blade of the inflation vent for any obstacles or foreign objects. 1. Do not put your hand into the inflation vent or the air exhaustion vent. 2. Make sure no obstacle blocks the inflation vent and the air exhaustion vent. 3. To prevent foreign objects from blowing into your eyes, keep the inflation vent and the air exhaustion vent away from your eyes. 4. Children under 12 years old must use this product under adult supervision. 5. This product can only withstand a minimal amount of liquid, so do not soak it in water or leave it out in the rain.

【Faster than Other Air Pumps】: The professional electric air pump operates at full power with a stable wind speed of 300L/min and a maximum power of 12W. It can reach 4000 Pa pressure and operate at full power for up to 35 minutes when the power is activated for two seconds.

【4 Nozzle Sizes】: The mini air pump comes with 4 different air nozzles suitable for use with air cushions, swimming pools, sofas, water beds, boats, pool toys, swimming rings, and more. The STIFFOUR air pump can also remove excess air for the storage bag, but it cannot reach a vacuum state.

【Portable & Small & Wireless】: The size of the Portable Electric Air Pump (2.1 * 2.5 * 3.2in, 0.32lb) is only half the size of a cell phone. The rechargeable electric pump saves storage space and comes with a storage bag for the air nozzles and USB cable. It is an essential tool for quick and easy inflation/deflation, more effective than most manual pumps on the market.

【Instructions for Use】: When you receive the STIFFOUR air pump, please charge it first. A red indicator will remind you when the power is less than 20%. If the power falls below 3.0V, the pump will stop working, and a red indicator will blink for 5 seconds before turning off. It is necessary to charge the air pump to continue working and prolong its life.

【1 Gear Mode】: Press and hold the air pump opening key for 2 seconds to enter wind gear 1. Press the key again to enter wind gear 2. The first gear is an automatic mode, and the air pump will automatically shut down after continuous operation for 5 minutes. Long press again to restart if necessary.

【2 Gear Mode】: During operation, press the open key again to enter the second gear. The air pump will work at maximum power and automatically shut down after 5 minutes to protect the motor system.
