The Magnetic Wireless Car Charger outputs 5W or 7.5W of Qi wireless charging, and it needs at least 12W (5V, 2.4A) of input power to work. Most newer cars have a USB-A port for charging, and some include USB-C ports. If your vehicle has no USB ports but has a DC (cigarette lighter) port, you can use a USB car charger adapter and a compatible cable to power it.
