Charging an Apple Pencil Pro without the iPad

I am a student who uses the iPad and Pencil Pro a lot but with the iPad case and Charge Friendly ortho-grips I use for the Pencil Pro, it's a little cumbersome to constantly adjust everything just to attach it to the ipad when it's dying. Is there a compatible charger that is separate from the iPad, or will there be an external charger for the Pencil Pro eventually?

Any thoughts/suggestions are appreciated!
