Pros: Works perfect! it charge 100% and more 30% in only one batery charge! Under the sun ligth here in Brasil it fully charge in 2 and a half hours. in day ligth it charges in 4 or 5 hours. Its possible to charge together: Plug the iphone in the batery and the barety in the power suply. I didnt test charge the phone in the sun ligth yet
Very compact, looks elegant and robust.

Cons: The male plug should have a better cover.

Other: Take it now! Amazyng and cheap gift for any iphone user!

Pros: Able to charge phone when away from a power outlet.

Cons: Mine came with a dent. The part that plugs into the iphone is bent and raise up. There is something that rattles on the inside.

Other: Affordable emergency charger for iphone. I just wish mine came in good condition, rather than slightly damaged.

Pros: -The Battery is easy to use and to handle -High recharge Rate (iPhone 4 20% --> 100% while Phone is passive) -Direct charge via iPhone plug or charge by solar panel

Cons: -The power LEDs are shining even when you are charging your Phone. Annoying at night... -Some small scarcities -Charge indicators are all "full" before the Battery is -Solar Charging needs direct sun exposure to work

Other: Even if there are some cons none of them will keep me away in re-ordering that product again. If you know about the weaknesses its a great product for are good price. Strong buy :)
