Apple Pencil 1 for iPad A16

See:

Pair Apple Pencil with your iPad - Apple Support

The first generation Pencil is charged and paired from iPad A16 using the iPad charging cable - and an Apple USB-C to Apple Pencil Adapter:

New first generation Pencils now ship with this special adapter in the box along with the Pencil. However, some older stock purchased from retailers may lack the USB-C to Lightning adapter - and may instead have an older Lightning to Lightning Adapter.

For owners of older first generation Pencils, or for “old stock” new Pencils, the new special adapter can be purchased directly from Apple as an accessory.

Did you look at the first image in my original reply - and the preceding link?

The Adapter is connected to the Apple Pencil's Lightning connector. The iPad's USB-C charging cable is then connected to both the Adapter and the iPad.

You're very welcome.
