Hello everybody! Besides the fact that if you plug the pencil in the ipad it will charge pretty fast (I'm trying now, I would say 2%/minnute or faster), you can buy it from the website: http://www.apple.com/shop/accessories/all-accessories/power-cables?page=2
I called the number provided by TerreSpencer (thank you!) and they said they couldn't send one to me, that I could buy it at the Apple Store and that online you have to go to the home page, then scroll down and go to shopping (or something like that) then accessories, power and adapters and you will find it there. (But it is expensive if it is the one that I think it is, it is about 20$; I mean, not expensive but more expensive than what reported above). But it wasn't the little tiny guy but another kind that would work. I think. I will try. 8And there are many pages to scroll, I stopped at page #2
I plug my pencil in at around 7:48 am with 50% charge and now it is 8:13 am and it is 100% charged; the ipad went from 100% to 98% (I was also using it, I think 50% charge for pencil would get 1% from the ipad If not in use). At least this is free...
I hope this was helpful!
thank you and good luck
