12V Socket Splitters
Turn one 12V outlet into several ports for devices and accessories
A 12V socket splitter expands a single cigarette lighter outlet into multiple sockets and USB ports, so you can run a phone charger, dash cam, and tire inflator at once. Many include a small display, switches for each socket, and fast-charging USB or USB-C ports. It is a simple way to add power for everyone in the car.
The thing to watch is total power draw, since every device shares the outlet's amperage and fuse. We curate top-rated picks on Amazon so you can compare socket counts, USB output, and cable length. Add up the wattage of what you plan to plug in and stay within the outlet's rating to avoid blowing the fuse or overheating.
