This is a practical solar powered gadgets bag. As we can see from the images, the gadget bag features a large 8 x 12-inch super-efficient flexible solar panel on the top in order to absorb solar power and push up to 1000mA at 5.6v via USB cable that connects into the main compartment in full sun. If you’re not directly charging your gadgets, the energy will be stored into a 800mAh rechargeable battery as backup battery. The gadget bag comes with two zippered pouches, the large one measures 8 x 12 inch for iPad, while the small one is 8 x 5 inches for a Kindle. In addition, the unique piggyback design allows you to apply the solar powered bag to your existing backpack.
The piggyback solar powered gadget bag is priced at $119.99 USD. If you’re interested, jump to ThinkGeek for more details.
