Can I purchase a Apple Pencil Charging Adapter?

The inline charging adapter is not sold by Apple as a replacement item - however, if you contact Apple Support and ask very nicely, they may be able to help. Similarly, should you visit the Genius Bar at your local Apple Store, along with a healthy approach to requesting help, they too might be able to assist.

Alternatively, it is often reported here that is possible to purchase a third-party replica from a popular online retailer or auction site. Being totally passive, the non-OEM part carries little risk of damage or other issues.

Apple Support can be contacted using the Get Support link at top-right of this page.

I hope this information proves to be helpful to you.

You can order the adapter from Amazon. I lost mine almost immediately!

There are plenty of third party makers of these Pencil charging adapters on Amazon.com.

Best of Luck to You!
