<p>Wall charger features GaN technology to provide fast charging for your device in an exceptionally compact and convenient size. Gallium nitride (GaN) is a high-performance alternative to the traditional silicon used in charging devices. GaN transistors produce less heat to let components be closer together and give you a much smaller charger with all the power of a big one. Foldable prongs make it as small as possible when not in use for easy storage and transportation. Fast-charging technology lets you charge a MacBook Air from 0 to 50 percent in just 70 minutes, or fast charge an iPhone 8 or later from 0 to 50 percent in 30 minutes. Built-in protection keeps your devices safe from overcurrent and overvoltage damage. USB-C Power Delivery certification ensures reliable performance with all compatible devices for safe use. Wall charger supports a wide range of USB-C devices, including those from Samsung and Google as well as MacBook Air, iPad Pro, iPhone 8 and later models.</p>
