Why not inductive magnetic charging on the side of your pro? don't plug it into anything, out o charge? stick it to the side. No plug necessary (and you could have a female lightning plug on the back of the pencil to take regular charging).
Inductive charging is nice, but has a couple drawbacks that Apple tends not to take:
1) Charging speed
2) Wastes power on the induction, so it hurts battery life on the iPad itself more to charge a stylus this way.
3) Uses space for the induction coils, and tends to require certain shapes to work. Less optimal shapes makes #2 even worse. Note the shape of Samsung's charging station, and the Apple Watch charger. The round design is actually done intentionally.
Apple in general tends to be slightly dubious of wireless charging in general unless they have to do it. In the case of the Watch, inductive was likely picked in order to make things easier when making it water resistant, despite the losses involved. And the losses are why Apple tends to not like wireless charging, from what I've seen of them. They have in the past been determined to be friendly to power bills and avoid bad things like phantom loads.
And as someone who has played with coils enough in EE classes ... hope the coil was built properly and doesn't fail early (it will always fail eventually, coils tend to erode themselves over time). I'm not sure how much I'd trust Apple to get it right when they've had materials problems with MagSafe cables in the past, and a charging coil has similar failure modes.
Or how about using the 3 pin magnetic port that the keyboard uses? I'm sure it's capable of providing some juice, it powers the keyboard afteral.
Except the port itself isn't magnetic. It snaps to the side via magnets, but it is the force of the magnets that causes the spring-loaded pins in the cover to come into contact with the pins. The catch here is to make it work with the pen, the pen now needs to be shaped like the side of the iPad.
Otherwise, perfectly fine. But not really "Apple". IMO.
maybe a mechanical sliding clip button thingy that changes the plug from male to female so that both options are available?
this would have felt a lot more "apple" in their design philosophy than what the current pencil is
Apple, the company trying to reduce mechanical parts,
adding a mechanical part? The problem I see here is that it complicates all the wiring for the thing, adds something that can fail early, and reduces the space for the battery. This thing is already pretty big as it is, and I'm not sure I'd sacrifice battery life or size to get this mechanism.
That said, if done right, this one would actually be the most Apple-like. But mechanical failure seems to be something Apple has been fighting on many fronts, reducing the moving parts where they can get away with it. So even then, they probably wouldn't go for this.
Honestly, a simple, non-mechanical adapter is less prone to failure than anything mechanical (assuming no manufacturing defect). It'd be neat if it was something a little cleaner, but on the balance, I'm not actually annoyed by this approach. I don't have to carry spare batteries (SP3), or replace it when the battery dies (SP4), or be near a charger when it dies (Apex Fine Point, 53 Pencil, etc, etc). Odds are I'll charge it when I'm at my desk with the adapter shown in the original post, but if I forget, I won't be out of power in the field. That charge cable won't come with me 90+% of the time.
It is reasonable to conclude that this is a new development since Apple had not mentioned the availability of an adapter before this point. When the Pencil was first announced and people were poking fun about the way the Pencil is to be charged, that would've been the time to respond with "well there's an included adapter that will allow you to use your cable".
Actually,
they kinda did, just not very loudly:
Ars Technica said:
The accessory charges with a Lightning connector that plugs directly into the iPad Pro or an included dongle—this connector is used to pair the Apple Pencil with the iPad Pro the first time you use it.
I dunno if I would have mentioned it in a PR release or anything though. Tempering expectations is all well and good, but I'm really not sure what coming out with that information would have done. The "what is in the box" will be available when pre-orders start, and that information will get folks on the fence about this thing to either order or not if it happened to be a problem. I'm honestly wondering if this is one of those cases where trying to correct some wrong impressions is a total waste of breath. Plus it lets you lose control of your messaging during important advertising windows.
