12V Automobile Digital Clock & Thermometer with Car Dashboard Compass

Driving in unfamiliar areas? Worried about freezing roads? Want to monitor your battery voltage? The 12V Car Digital Clock & Thermometer with Compass puts five essential functions in one compact dashboard device. With indoor/outdoor temperature monitoring, a digital clock with calendar, battery voltage readout, compass direction, and even a hidden parking phone number plate – this is the ultimate driving companion.

What You Can See at a Glance

• Digital Clock with Calendar:
• Displays current time (12/24-hour format)
• Shows year, month, and date
• Never lose track of time or appointments while driving

Indoor & Outdoor Thermometer:

• Internal Temperature: -20°C to +70°C (monitors cabin temperature)
• External Temperature: -50°C to +70°C (monitors outside conditions)
• External Sensor: 1.5-meter cable allows you to place the sensor outside the vehicle
• Accuracy: ±1.5°C – reliable enough for practical driving decisions
• Easy Identification: "IN" icon for cabin temperature, "OUT" for external

Ice Alert Warning System

When the external temperature drops between 0°C and 4°C, an ICE icon appears on the display. This early warning alerts you to potential black ice on bridges, overpasses, and shaded road sections – giving you time to adjust your driving.

• Car Battery Voltage Meter
• Displays your vehicle's battery voltage in real time. Monitor:
• Alternator charging performance
• Battery health before cold starts
• Parasitic drain when parked
• Early warning of charging system issues
• Digital Compass

Know your direction at all times – especially useful when:

• Driving in unfamiliar cities or rural areas
• Navigating without GPS signal
• Orienting yourself during poor visibility (fog, heavy rain, snow)

Hidden Parking Phone Number Plate: On the back of the unit, a small temporary plate allows you to write your phone number. Leave it on your dashboard when parking in unfamiliar areas – courteous parking made simple. Wipe clean when no longer needed.

Dual-Color Backlight

Choose your preferred display color:

• Blue Backlight: Modern, cool tone – easy on night vision
• Orange Backlight: Warm tone – matches many OEM dashboard lights
• Press the side button to switch between colors instantly.

Easy Installation – No Mechanic Required

• Step 1: Plug the device into your vehicle's 12V cigarette lighter socket.
• Step 2: Run the external temperature sensor cable to the car door edge and place the sensor outside (avoid direct sunlight and exhaust heat).
• Step 3: Start your car – the display powers on automatically.
• Step 4: Mount on dashboard using included adhesive pad or place in a convenient location.
• No wiring, no tools, no professional installation needed.
