You can charge the original Apple Pencil by inserting its Lightning connector into your iPad’s Lightning port. To charge a second generation Apple Pencil, attach it magnetically to the right side of the iPad and make sure your iPad’s Bluetooth is enabled.
How long does it take to charge the Apple pencil?
There are 2 main ways to charge your Apple Pencil. In my experience it takes about 15 minutes to fully charge the Apple Pencil using the Lightning port. In 2 mins you can charge it by +15%, which enables you to work 2 hrs with it. Apple claims that in 10 seconds of charging you can get 30 minutes of work out of it.
