The pencil comes with a female/female connector dongle so just use your regular charger cable with the lighting connector, the adapter, and the pencil plugged into the other end of the connector.If ipad gets USB-C, how will the apple pencil be charged? Another dongle?
I keep a dedicated charger with a short lightning cable plugged in and the adapter dongle plugged and taped to the lightning connector of the cable. Then I just plug on the pencil when I need to.
I also replaced the cap on the pencil that covers the lightning connector with a different cap that has a standard rubberish stylus tip on it.
