I would have expected that an iPhone power adapter that has a USB plug as output would produce the same kind of current as another one with a USB plug, such as the Amazon Kindle adapter.
Not so, unfortunately. When I did, the battery icon on my Kindle started showing the “charge” lightning bolt, but I realized later it just kept on losing juice. Eventually it died and had trouble restarting, until I charged it with the right plug again.
It might be the difference in power (the iPhone adapter outputs 5V/1A, the Kindle 4.9V/.85A).
Kind of annoying for longer, computer-less trips (will have to bring 2 cables, and 2 adapters), although the Kindle’s battery seems to last quite long, especially if you don’t use the wireless.
Actually, did you know that charging a MBP on a adapter that was given with a Macbook (non pro-white) gives identical problems? The charger of the normal MB didn’t turn green when connected to the MBP. It’s weird, but finally trying my own adapter that was given with the MBP made my MBP boot as normal as it was completely empty.
How bout a new standard adapter that make phones, mp3 players and laptop run from one single adapter (with or without additional plug entries)…
Yeah, at least mobile phone makers have agreed on mini-USB as the standard for their products, and hopefully there will be no discrepancies in power levels there…
wow, thank you for this, I thought the same thing and figured my kindle was defective but it wasn’t!
Absolutely true. Almost snuffed my Kindle charging it with a iPhone 220V > USB adapter.
