Griffin Powerblock Reserve rethinks its

Griffin had a couple of years in sales an extra battery for the iPhone and other smartphone called Powerblock Reserve, but this year has decided to renew the design.

Now, the power block is a "block" compact, wrapped in a white plastic frame with a collapsible power plug on one side (unfortunately only available at the moment it seems the American standard), and a USB plug on one of the sides. Inside is a 2000mAh battery capable of taking an iPhone from zero to 80% charge.

The form is fairly compact and pleasant to watch, a model that compares favorably connected to your iPhone. Apparently you need a cable to connect the power block, Reserve, because it is not a dock. If you have an IOS device of some kind, you need a cable connection, which is included in the package only if you intend to spend $ 60. The wireless model costs $ 10 less.
