Why Choose STEELMATE V12?

The V12 is designed for drivers who want more than a basic jump starter. It combines several essential emergency functions into one portable device.

When the vehicle battery is weak, the V12 can provide jump-starting assistance. When tyre pressure is low, its built-in compressor can inflate the tyre without requiring a separate compressor. The USB output provides additional power for mobile devices, while the emergency LED light is useful in low-light roadside situations.

With support for engines up to 5.0L petrol and 3.5L diesel, the V12 is particularly suitable for drivers who need a higher-capacity emergency device.
