- Latest technological breakthrough - Features a high-quality brushless motor, optimized air duct design, and advanced wiring design to distribute heat evenly. This helps prevent overheating during use, so the pump can run continuously until its power is exhausted, unlike some devices that require cooling breaks. - Ultra-mini and portable - Weighs 4.9 oz and measures 1.9 x 1.9 x 2.8 inches, smaller than a typical fist. Lightweight and easy to slip into a backpack or even a pocket. - Built with an ABS shell and well-sealed surface technology. One-button operation for simple use. Ideal for outdoor camping, hiking, beach trips, and keeping in storage bags at home or in a car, without depending on a fixed power supply. - Quick inflation and deflation - Powerful motor delivers up to 4 kPa and a maximum wind speed of 280 L/min, with a 30 W rating. - Inflation times (typical): about 15–20 seconds for a swimming ring, around 100 seconds for an air mattress, 2–3 minutes for an inflatable pool, and 30–40 seconds to compress a vacuum storage bag (sizes vary). - Air pressure sensing - Built-in air pressure sensing device automatically adjusts speed as the internal pressure rises, helping fill inflatable items to the desired level rather than underinflating. - Rechargeable power and nozzles - Built-in 1200 mAh lithium polymer battery. Quick charging via USB Type-C, with a charging time of 2–3 hours using a 10–20 W adapter, after which it can run continuously for about 20 minutes. - Comes with 5 different nozzles to fit most inflatable products. Note: not suitable for inflating tires, balloons, or basketballs.
