An ingenious messenger bag weighing only 200 grams that is capable of holding smartphones, tablet PCs and other high-tech devices. The best part is that they can be charged directly within the bag thanks to a fully integrated solar cell with removable flap and a USB port. Not enough sunlight? You can use buffer batteries to get the job done. This is the first of its kind ever invented and features high-quality materials with superb workmanship.
