Universal 12 V Cigarette-Lighter Voltage Meter

This compact meter plugs directly into a 12 V cigarette-lighter socket and shows real-time battery voltage on a high-contrast LED display. It draws only 0.1 A and requires no wiring or modification, so novice drivers can start monitoring instantly. The ABS housing measures 2.8 by 1.57 by 1.17 inches and weighs 0.5 ounces.

Suits owners who want a simple plug-and-play

It is not suited for technicians who require data logging, configurable alarms or an input range beyond 30 V, nor for anyone needing to monitor higher-voltage electrical systems. The single decimal-place readout covers basic health checks but lacks the resolution for precision diagnostics.

0–30 V input range with 0.1 V resolution

The meter accepts 0 to 30 V input and displays voltage to one decimal place, letting you confirm that a 12 V battery stays within healthy limits. The 5.5 V output rating is an internal reference and does not extend the measurable range.

Questions about this item

Does the 12 V / 0.1 A meter draw enough power to warm up or make noise when left plugged in all day?

It draws only 0.1 A at 12 V, so heat and audible noise are negligible during continuous use.

My car has a standard cigarette lighter socket — is anything else required before the display lights up?

No extra parts are needed; just insert it into a 12 V lighter socket and the LED readout activates immediately.

Will the 0–30 V input range still protect a 12 V battery if I keep an older charger connected at the same time?

The meter simply reads voltage up to 30 V; it does not regulate or protect the battery, so the charger’s own controls must handle safety.
