We mentioned the PowerBag and we mentioned our hands on with the myCharge Duet iPhone battery case. And well, in addition we also checked out the Folio iPhone battery case from myCharge. This one was equally nice in quality. The myCharge Folio brings a matte case and magnetic closer. It also has a look very similar to that of the Smart Cover for the iPad. Of course, unlike the Apple Smart Cover the myCharge Folio brings a 1300 mAh battery along with a USB power-in cable. This case retails for $79.99 and as you will see in the images below — it is available in a variety of colors.
