Boy, I typed this question into google and spent 20 minutes reading arguments that started to range into 240v 3 phase instead of getting an answers.:huh Taking a trip and packing along iPad, Sansa mp3 player, and Motorola phone. Rather than having 3 wall warts in my bag, I thought I'd just take the iPad 10w charger and the USB -- device cables. Any issue with this? I'm not a techno-geek so I don't know if the USB jack on the apple charger is wired like every USB jack. I'd do a test but I didn't want to fry my non-apple devices just days before the trip. To avoid this, I figured one of you FF geniuses had tried the same and either had success or let out the magic smoke, allowing me to learn from your success/failure.
