DROK Digital Voltage Temperature Monitor 12V 24V Thermometer

SKU CH-TGCH-80ECS

Monitors 12V or 24V battery voltage and cabin temperature while charging devices via a 5V 2.1A USB port

  • Product colorBlue,Red
  • Charge devices on the go with built-in 5V 2.1A USB port
  • Monitor battery voltage and cabin temperature at the same time
  • External sensor avoids direct heat for more accurate readings
  • Built-in fuse protects vehicle electronics during use
  • LED display stays readable in low-light conditions

Vehicle Voltage & Temperature Monitor

This 12V and 24V digital monitor plugs into a car power socket to show battery voltage and interior temperature at the same time. A built-in 5V 2.1A USB port lets you charge a phone or tablet while driving. The LED screen stays readable in low light.

Practical Limits of the 12V/24V Socket

The unit only works from a standard 12V or 24V vehicle outlet, so it cannot be used on household mains or other DC sources. Accuracy depends on placing the external sensor away from direct sun or heater vents. The internal fuse protects the car wiring but does not extend the voltage range.

Fahrenheit-Only Temperature Readout

Temperature is displayed in Fahrenheit only, which suits drivers used to that scale but makes the monitor unsuitable for anyone who needs Celsius readings. If you require metric units, this is not the right part.

Questions about this item

Which colour should I pick — blue or red?

Both versions share the same 12V/24V monitoring, external temperature probe, built-in fuse and 5V 2.1A USB charging port, so choose the colour that matches your dashboard.

What does the dual display actually show while I'm driving?

It shows the vehicle battery voltage and the interior temperature in Fahrenheit at the same time, letting you watch both without switching screens.

How does the 5V 2.1A USB port limit what I can charge?

The port delivers up to 2.1A at 5V, so phones and small tablets charge at normal speed, but larger devices that need more current will charge more slowly.
