Four-Socket Splitter for 12V and 24V Vehicles

This power splitter cord connects to a standard cigarette lighter plug and provides four additional sockets plus three USB charging ports. It supports 12V and 24V electrical systems, making it suitable for cars, heavy-duty trucks and other commercial vehicles. The unit delivers up to 108W at 12V or 216W at 24V for high-draw accessories.

Independent Switches Free Up Unused Ports

Each of the four sockets and the USB ports has its own on-off switch alongside a master switch, so you can cut power to individual devices without unplugging them. This reduces standby drain on the vehicle battery and lets you run only the gear you need at any moment. A built-in LED display shows real-time voltage from 11.5V to 14.9V on 12V systems and 23.1V to 27.3V on 24V systems.

Passive Cooling With Low Self-Consumption

The adapter relies on natural convection and draws only 0.281kg of weight in a compact 6.4008 x 8.7884 x 17.7038cm housing, so it adds negligible load to the cabin. No fan means silent operation while charging phones, tablets or powering dash cams and fridges. The 3.3ft cable routes cleanly to the front socket without clutter.
