The Apple Pencil is a wireless stylus for certain iPad models that lets you can take handwritten notes, sketch, draw, and paint, as well as control the iPad. Because it's wireless, you need to charge it occasionally.
There are two versions of the Apple Pencil. They look and work differently, and are designed for different iPad models. For more information on how to differentiate Apple Pencil models, and which iPad models they work with, see our article "'How much is the Apple Pencil?': A breakdown of Apple's advanced iPad styluses, including their prices and which iPads each works with."
Each Pencil uses a different method to charge.
But no matter which Pencil you have, it charges quickly. You get about 30 minutes of charge in roughly 15 seconds, and the Pencil fully charges in about 15 minutes.
