A:Answer I'm not sure which adapter you mean. There is an adapter included with the Apple Pencil, Gen. 1, that allows you to plug it into a USB cable and charge it on your computer or the wall outlet. This particular adapter has Lightning Ports on each end, one for the pencil and one for the USB or USB-C cable. If this is the adapter you mean and you need a new one, you should contact Apple Support (1-800-275-2273). I know Apple Store and other retailers sell replacement tips for Apple Pencils, so they may also sell this power adapter.
