Bought this off of Groupon when it went for 53 bucks all inclusive. I highly recommend the product, it holds a lot of juice and comes with both 1A and 2.1A USB slots which can really juice up my iPhone in no time.

At least eight hours according to my completely unqualified guesstimate, and 15 hours according to an Amazon reviewer although they didn't specify the power output of their charge source. Using the same misguided math from my guesstimate suggests they might have been using a ~1.1 A charger.
(My guesstimate is based on the specified 17 Ah capacity and the 2.1 A input and my layman assumption that this means we can expect 17 hours for a charge at 1 A and 8 hours for a charge at 2.1 A. It might be completely backwards though; I'm no electrical engineer.)
edit: Another reviewer says the included instructions claim 8-10 hours for a full charge, so maybe my math isn't that off here. Or it's a coincidence! :-)
