- peterwwillis 13y agoThat would not work. Data pins are used to provide power negotiation, and in Apple's case using a proprietary protocol. At the very least you need some specific voltages on the lines to make it charge. http://www.idownloadblog.com/2012/05/21/apple-power-adapter-teardown/ http://www.idownloadblog.com/2012/05/21/apple-power-adapter-... http://learn.adafruit.com/minty-boost/icharging http://learn.adafruit.com/minty-boost/icharging
- mindslight 13y agoI imagine basically all of those convenience ports only put out 500mA anyway, so the negotiation isn't needed.
- jonny_eh 13y agoiPads require more juice. Whenever I plug my iPad into anything other than Apple's 10W adapter or a Mac, nothing happens.
- MichaelApproved 13y agoI plug my original iPad into other USB devices that put out 5W and it still charges. The iPad says it's not charging but it does, slowly.
