If you're often on the road and want to charge multiple devices simultaneously using the 12V/24V car cigarette lighter, the Joyroom 3-way car charger makes it possible. Simply plug the splitter adapter into the car's cigarette lighter, and you can charge all your electronic devices like your phone, tablet, iPod, GPS, etc., using the appropriate car adapter. With 5 USB ports and 1 USB-C port, you can also charge your smartphone, MP3 player, or tablet directly via the USB/USB-C charging cable at the 12V/24V car distributor without needing a car adapter. Each DC socket is equipped with its own power switch, allowing you to turn on only the sockets that are currently in use.
