Battery Charger – With charging LED – DUAL CHARGER is the wall charger that offers the perfect solution to simultaneously charge two Apple devices, allowing the use of both the USB-C to Lightning cable included in the new iPhone packaging and USB cables. When used alone, the 20W USB-C port delivers maximum charging speed for iPhone 8 and later models. When both ports are used simultaneously, the charger reduces the maximum output power to 15W total to ensure safe charging.
