Anyone know a good recharging unit I can get for under $40 at BestBuy, Staples, Radioshack, or the Apple store?

I was thinking this one this one but it doesn't say exactly how much charge it holds. I want one that at least doubles the power (As in has a whole battery's worth).

Anyway, basically I want some other opinions before I buy from people that already have them.
