Apple's new iPad mini is fast-charge capable, but not with the adapter in the box. Apple's specifications say the device can reach up to a 50% charge in around 30 minutes when used with a USB-C power adapter capable of providing 35W or higher, but they are sold separately ($59) – the iPad mini comes with a 20W USB-C power adapter. The new OLED-equipped iPad mini features an 18.9-watt-hour battery rated for up to 10 hours of web browsing or video.
