One Device. Two Functions.

Charge your phone. Light in seconds. Drive without the clutter.

Designed for traditional 12V lighter sockets with dual USB charging and fast electronic heating.

The smarter 2-in-1 solution for adult smokers on the road.

Mrk 4 USB combines dual-phone charging and cigarette-lighting capability in a single compact automotive accessory, helping reduce clutter and minimize distraction inside the car.



One Compact Device for Charging and Lighting

With Mrk 4 USB, there’s no need to remove your charger and search around for your lighter again. The unit stays in place inside a compatible cigarette lighter socket. When charging mode is active, the blue LED shows the USB ports have power.

When you need the lighter function, simply press the button. The charging power is disconnected while the element heats up, helping protect connected devices. The orange LED indicates heating is in progress, and the red LED shows when the element is ready—typically in about 10 seconds.

Unlike a standard car cigarette lighter, Mrk 4 USB does not pop out. It remains seated in the socket recess for a more stable, streamlined experience.
