Hello everyone, hope this isn't a stupid question, but I will risk asking it anyway. Got my iPad two days ago and am digging it, very nice device and will be a great travel companion when I'm traveling for business and do not want to bring along a personal laptop. On to my question. I have a portable Belkin surge protector where I normally plug my iPhone into the USB connection to charge and it works perfectly. Well, I plugged the iPad in through the same connection and I saw a message of "not charging" on the iPad until I used the adaptor that came with it. Is this normal, can I only charge the iPad with the provided adapter? Again sorry if this is a stupid question, but its got me wondering. Thanks in advance everyone.
