Accurate Detection and Safety ProtectionFour preset inflation modes (bicycle, motorcycle, car, and ball) make it easy for beginners to choose. The full-screen design and smart digital display allow for easy reading and observation of tire pressure status. Set your desired tire pressure to avoid safety hazards from inaccurate tire pressure. It shuts off automatically when it reaches the preset pressure, making it very safe to use.
