Why didn't Apple just make the Pencil's charging port be a female Lightning port? The idea of having the Pencil stick out the bottom of the iPad Pro, was ridiculous thinking on their part. It's not like it's so hard to use the charging cable from the iPad to charge the Pencil.
Wat? The reason you want the Pencil to have a male charger is so you can plug it into the iPad Pro and get a charge anywhere without the need to haul this adaptor along. It was a far smarter move than you're proposing.
