This charging backpack holds a battery pack that can charge a variety of different technological devices.
Most people have a multitude of devices that they use throughout the day -- and those same devices are drained of battery and must be constantly recharged. Since outlets are not always available throughout the day, this backpack holds a battery pack that can power those devices. The charging backpack can give energy to HP laptops once, a tablet three times and a smartphone up to 10 times. The backpack comes with USB cables, making the user's life much simpler.
This bag would be extremely useful for situations in which power outlets are not immediately available, including camping trips, hiking and days at the beach.
