1、SOLAR POWER AND USB CHARGING: The RV TPMS offers 2 convenient charging options. Equipped with a solar battery panel, it can charge independently in the sunlight to ensure battery life. Additionally, USB Type C charging can be used as a backup when there is no sunlight. These dual charging methods enhance the tire pressure monitoring system with 6 external sensors, extending its standby time and usability. 2、REAL TIME MONITORING AND EASY SETUP: Explore 5 alarm modes and easily set alarm thresholds using the tire pressure monitoring system. You will unlock 5 unique alarm modes, including quick leakage detection, high low pressure alerts, high temperature warnings, and sensor low voltage notifications. Once paired, the system effortlessly sets the current pressure as a reference point, simplifying the configuration of alarm thresholds. 3、ACCURATE MONITORING WITH SENSORS: The TPMS utilizes low power sensors that extend battery life for up to 3 years. With its compact size, lightweight design, and high tire pressure sensing accuracy (error range not exceeding 2 PSI), installation is effortless. Designed to be water resistant, windproof, and snowproof, it can further expand the sensing range to over 130 feet with a repeater to ensure full coverage. 4、UPGRADED COLOR LCD DISPLAY: The system features an intelligent color LCD screen that automatically adjusts the backlighting in different lighting conditions to ensure a clear data display. The LCD display mode ensures high resolution, high definition and no flashing status, allowing the driver to easily access tire pressure and temperature information when needed. 5、POWER SAVING MODE AND VIBRATION ACTIVATION: If the vehicle is left stationary for 10 minutes without charging, the system will automatically enter power saving mode. In this mode, the display will turn off and no sensor data will be received. Simply press any key or vibrate the display to reactivate the system and return the TPMS sensor's tire pressure monitoring system to standby mode.
