Compact dual-display LED voltage and temperature monitor with external sensor and cigarette-lighter plug

DROK 12V 24V Voltage Temperature Monitor 10-170°F

SKU CH-JWB4-4V1JC

Dual-display monitor shows 12V or 24V battery voltage and 10–170°F cabin temperature simultaneously with an external sensor for accurate readings

  • Commercial or home useOutdoor
  • Dual LED display shows battery voltage and cabin temperature together
  • External sensor bends away from heat sources for accurate 10-170°F readings
  • Built-in fuse protects vehicle electronics during 12V or 24V use
  • Bright LED screen stays readable in dim light conditions
  • Compact 2-in-1 meter monitors both voltage and Fahrenheit temperature

Dual voltage and temperature monitor

The DROK meter plugs into a 12V or 24V cigarette-lighter socket and shows battery voltage alongside interior temperature on a single LED screen. It is aimed at drivers and fleet operators who want an instant view of electrical health and cabin conditions without using separate instruments.

Thermals noise and power

The unit draws its operating power directly from the vehicle socket and includes a built-in fuse for circuit protection. An external probe can be bent away from heat sources or direct sunshine so the 10 to 170 Fahrenheit reading stays accurate while the LED display remains legible in low light.

Build fit and freedoms

Compact plastic housing leaves dashboard space free and needs no permanent wiring or mounting hardware. The external sensor routes around trim panels to avoid false highs, letting you monitor a 12V or 24V system without sacrificing a power outlet or adding clutter.

Questions about this item

How do I install the monitor in my vehicle and what is the step people often miss?

Plug the unit into the 12V or 24V cigarette lighter socket for power; the step often missed is routing the external temperature sensor away from direct sunshine or engine heat so the 10-170°F reading stays accurate.

What maintenance or replacement will this monitor need over time?

The built-in fuse protects the circuit; if a voltage spike blows it, replace the fuse with the same rating to restore operation.

What limit appears first during continuous use in a hot cabin?

The temperature sensor stops reading above 170°F, so sustained exposure to higher heat will cause the display to max out before any other limit is reached.
