Here's something that a lot of people might not know: The Apple Pencil 1 comes with a female-to-female Lightning adapter, so you can attach the Pencil to any Lightning cable for charging.
If you bought a Magic Keyboard, Magic Trackpad, Magic Mouse, or iPhone in the last year or two, you already have a USB-C to Lightning cable.
Pop the adapter that you already got with your Pencil 1 onto an existing Lightning cable, and you're good to go. I keep mine stashed in the pencil groove of my iPad case.
And I'll be totally honest… I didn't know the Pencil came with one until somebody told me about it. I dug around in the box for the Pencil and found it.
