Features: It makes inflating low and flat tires in emergency-easier and more convenient. With the built-in LED light, you will not have trouble seeing what you're doing with your tire, even when you're working in-a shadowy garage, parked under a-broken streetlight, or broken down next to an unlit rural-road. Great for many types of tires: car, bike, motorcycles, SUV, ATV, rubber dinghy and also sports equipment and inflatables. High-precision chip, no error in pressure measurement. Connect the air nozzle to automatically detect the tire pressure without error. After setting the corresponding tire pressure, it starts to inflate and automatically stops. There is-no need to pay attention to the tire pressure value at all times. With a-large digital LCD display, the current tire pressure will be displayed, so you can monitor the accurate tire pressure at any-time. The LED light can provide long-lasting lighting, and the bicycles air pump can help you use the bicycles air pump at night or in the dark.
