Mili has released its Power Skin external battery + case for the iPhone 3G and iPhone 3GS, as well as its PocketPal foldable USB charger. First seen at the 2010 International CES, the Power Skin features a 1,200 mAH battery integrated into the case, which features a snap-on top piece for easy device removal, cut-outs for access to the camera, volume and power buttons, headphone jack, and ring/silent switch, and a pass-though mini-USB port that allows for the charging of the encased iPhone. Available in eight two-toned color combinations using black, white, blue, green, orange, and silver, it sells for $70. The PocketPal is billed as the “world’s smallest mobile phone USB charger,” and offers foldable plugs for easy carrying and a 1000mA output; it too is available in a variety of colors and sells for $20. Both the Power Skin and PocketPal will also be available in a bundle for $80.
