Reliable in-car time and temperature display with dual power and smart energy saving Key benefits Continuous operation: Dual power modes (solar and USB) keep the display running. Use solar charging while parked in sunlight and plug in via USB when solar power is low. Clear information any time of day: The solar-charged backlight illuminates the display at night and improves visibility in low-light conditions so you can read the time and temperature quickly and safely. Durable for the car environment: The display case is made from high-temperature resistant ABS, designed to withstand typical cabin heat without deformation or damage. Efficient power use: A built-in vibration sensor turns the display on when it detects movement and puts it into sleep mode after five minutes of inactivity to conserve energy. Product features and performance Power supply: Two options — solar charging plus USB backup. Switch to USB power when solar energy is insufficient. Solar charging: Absorbs sunlight during the day and provides illumination at night so the time and temperature remain readable in low light. Material: High-temperature resistant ABS housing suitable for vehicle interiors. Low energy consumption: Built-in vibration sensor automatically activates the display on movement; automatically sleeps after 5 minutes without activity. Practical use scenarios Night driving: The solar-charged backlight makes time and temperature easy to read without distracting bright lights. Parked in sun / long trips: Solar charging keeps the unit powered while the car is parked in sunlight; plug in with USB during extended night use or in low-sun conditions. Short drives and stop-and-go city use: The vibration sensor wakes the display only when needed, extending charge and minimizing power draw. Compatibility and installation notes Designed for use inside a vehicle cabin; housing material and functions are optimized for the automotive interior environment. Power via standard USB when solar charging is insufficient; no special adapters required beyond a common USB cable or car USB power source. What it delivers A durable, energy-efficient in-car clock and temperature display that stays readable day and night, reduces unnecessary power use, and is built to tolerate typical car interior temperatures.
