Anyone had any experience buying the $2 cheapo adapters from HK instead of the $30 Apple branded one? (Easy to find in the $20 range if you shop) My thought is - ALL OF THESE are made in China anyway. Knock offs could be getting sold out of the same factory as the one Apple contracts with for all we know. And ultimately - if the spec isn't right - it won't work! I know this because I've tried other 120V to USB charging adapters and the iPad just says "not charging" if it doesn't like it.
