how many hours of charge does this give?

i'm just about to get a new contract with and iPhone 4s and i was thinking of getting a travel charger or something, there are a lot of them around but this one looks the most reasonably priced and most portable so was just wondering how many hours this would give to a 16gb iPhones 4s, thanks.

    I have a 4S and it's hard to give an exact answer since talk, data, idle condition vary. I estimate that has as much power as the a fully charged iPhone 4S so it doubles or more than doubles the usage time.
