I'm considering buying an 1st gen iPad for my son from an online acquaintance. But she has the smaller "cube" power adapter like the one you get with an iphone/ipod...not the larger 10W adapter. She swears up and down that the cube adapter was the one that came with her iPad (she purchased directly from Apple-original owner). I find this hard to believe. I thought all generations of iPads came with the 10W adapter from day 1. When you look at the iPad 1 refurbs for sale on the Apple website, they come with the 10W adapter. My question is: Was there ever a time, perhaps early on, where the original iPad only came with the smaller cube adapter instead of the 10W?
