- • Voltage Readout: Bright LED shows instant voltage readings for 12V and 24V systems
- • Best for: Drivers who want quick, on-the-spot battery checks for cars, vans and trucks
- • Not ideal for: Users needing detailed diagnostics or professional load-testing equipment
Simple plug-in voltmeter that reads both 12V and 24V systems through the cigarette lighter socket. Compact LED display gives continuous, real-time monitoring of battery voltage.
Instant, tool-free checks – with a cigarette lighter socket connection
Plugging into the vehicle's cigarette lighter socket draws power and links directly to the electrical system for an immediate voltage readout. No extra wiring or panel removal is required.
Quick plug-in checks save time at the roadside and for routine maintenance. Carrying a compact reader makes voltage checks straightforward before long journeys.
Works across vehicle types – with 12V and 24V compatibility
Designed to operate with the common 12V electrical systems found in cars and the 24V systems used in larger trucks and SUVs. The unit displays voltage appropriate to the connected system.
A single meter suits family cars as well as commercial vehicles, reducing the need for multiple testers. Useful when servicing mixed fleets or towing a heavier vehicle.
Clear status at a glance – thanks to a bright LED display and continuous monitoring
A high-visibility LED screen presents battery voltage in real time and updates as charging status changes, for example during engine running or alternator charging.
Readable in daylight, so checks do not need a torch or ideal lighting. Observing voltage rise while charging helps confirm the alternator is functioning correctly.
