【EASY TO USE 】Plug the inflator pump's power cord into your car's cigarette lighter socket, attach the nozzle to the tyre valve, and press the power button to fill up a 195-size tyre with air in approximately seven minutes. To prevent the internal cylinder of the product from overheating, please turn off the product after ten minutes of continuous use and allow it to cool for ten minutes to prolong the life of the product. 【POWERFUL PERFORMANCE】The air pump can rapidly inflate car tyres to the desired pressure with a maximum capacity of 150 PSI. Swifter and more effective than conventional ones, and it includes a precise gauge that enables real-time monitoring and control over tyre pressure. 【COMPACT, CONVENIENT DESIGN】The compact design enables it to fit effortlessly into the glove compartment, seat, or boot, enabling you to carry it anywhere you go and find the best solution for any situation. The ergonomically designed handle ensures a comfortable grip, and the built-in LED light provides immediate emergency illumination. 【EXCELLENT WORKMANSHIP】Undergoes a revolutionary manufacturing process which upgrades all of the parts, including a new metal cylinder. This process greatly improves the wear resistance and durability of the inflator, ultimately leading to a significant extension in its service life. 【PRESETTABLE & AUTO SHUTOFF】Press the "R" button to set your desired pressure unit and the "+" / "-" buttons to set the desired pressure. The air compressor will automatically shut off when the tire inflation reaches the preset pressure. (Please make sure the pressure you set is higher than the current pressure of your tire).
