Those who have used a 2.5 HDD Enclosure will recognized this USB cable. I figure why not use TWO 10W Power Adaptors to charge the new iPad.

I'd test it out myself but to chicken *****. :eek:

Anybody who has a USB cable like this would care to try it out? ;)

I don't think it would damage the iPad nor would it charge it any faster. The iPad pulls the charge it needs.

I agree...

Those in the know, for 2.5 HDD enclosure, which plug acts as the power?
 
it wont charge your ipad any faster, cause the max it can take in is about 10W.
Just look behind your iPad, it's 5V and 2A.
so no matter how high the wattage your charger is, it's not going to be any faster.

Thanks for the info
 
Ya. I think the iPad will limit the amount of power coming in to avoid overheating the battery. But by all means- give it a go and post pics of whatever happens!:D
 
The iPad will either charge VERY slowly (drain less quickly really) from that setup since it will only draw 500mA instead of 2.1A it draws from the Apple charger if it can't detect that it's an Apple charger, or normal speed because if it does detect it it'll draw 2.1A. The iPad has no way to know what you've done, and the wiring isn't rated for over 2.1A anyways, so the iPad won't draw more. The charger's just an AC-DC adapter, it's not what determines current draw. It's just rated to handle a certain current draw. The iPad detects what the source is rated for so as not to fry a 500mA USB port...
