I've had phones with both sorts of connectors and could freely interchange =
chargers. I believe some of the older ones just don't deliver as much curre=
nt and might charge more slowly, that's all.
Also you can freely charge iphones from any USB source so, for the phones a=
t least, intelligence is in the device, not the charger. I'd imagine the sa=
me counts for the remote.
Apple don't strike me as the sort of company to produce two devices with id=
entical ports that can get destroyed if the chargers were swapped, their us=
ers wouldn't stand for it :)
Kind Regards,

Robin Bussell,

Subject: [OT] Apple Chargers, Old and New

	As an electronics experimenter, I feel kind of dumb asking this question b=
ecause it sounds so simple.

	We have an Appletv whose remote has the new Lightning connector on it. The=
 remote came with a cord but no charger.

	My wife has an older iPhone whose charger originally had the 25-pin Apple =
connector on it's charger. The Lightning cable fits it just fine but is it =
safe to use?

	If the charger is your basic USB 5-volt source and the intelligence for kn=
owing when to stop charging the battery is in the remote, itself, I would t=
hink it would be okay. If not, that remote might be a very expensive firecr=
acker.

	I don't have any good way to test for sure which is why I am asking. Again=
, the charger power adaptor was sold with the iPhone so it isn't just a no-=
name wall wart from who knows where.

Thanks.
