RT-603 Vehicle-Mounted Portable Tire Inflator With Light

The RT-603 Portable Vehicle-Mounted Air Pump Compressor—a car tire inflator suitable for bicycles, balls, and motorcycles—integrates a multitude of functions into a single device: tire pressure detection, automatic inflation shut-off, LED lighting, SOS warning signals, and USB charging output. This comprehensive feature set ensures it meets inflation requirements across a wide variety of scenarios. Equipped with an 18650 lithium battery (with selectable capacity options) and supporting a 7.4V operating voltage, the unit offers a maximum inflation pressure range of 0.35–10.3 Bar (5–150 PSI). It accommodates various inflation modes—suitable for cars, motorcycles, bicycles, and sports balls—and boasts a maximum airflow rate of 19 L/min, enabling it to complete inflation tasks quickly and efficiently. The RT-603 features a built-in high-precision tire pressure detection system with an accuracy tolerance of just ±1 PSI; this system monitors tire pressure in real-time, effectively mitigating safety risks associated with abnormal tire pressure. Its automatic inflation shut-off function ensures that once the target tire pressure is set, the device stops inflating automatically, thereby preventing over-inflation. A built-in LED light ensures the inflation area remains clearly visible during nighttime use or in low-light environments, while the flashing SOS warning function provides an added layer of safety protection during emergencies. Additionally, the RT-603 supports USB output (5V/2A), allowing it to serve as an emergency power bank for charging mobile phones and other devices. With its Type-C 5V/1A input, the device's rapid-charging design ensures you maintain sufficient power levels at all times, guaranteeing extended periods of use.
Included Accessories: 4-piece nozzle set, inflation hose, charging cable, and storage pouch.
