The Ultimate Travelers Backpack

          Keeping track of chargers is a hassle, keeping track of your chargers while traveling can be down right maddening.  Avid travelers will worry about making sure all of their devices have the right charger.  Even if you bring all of your chargers with you, there is no guarantee that you will be able to grab one of the few outlets.  What modern wanderers need is a travel bag that keeps your chargers in a single location.  Current consumer brands like PowerBag are starting to fill that niche by providing a built in 3000mAh battery pack designed to allow for charging of USB devices on the go, what is missing is the ability to connect devices that might not have the ability to charge by USB.  The backpack shown to the right is an over engineered solution for a traveler's power needs.

          This design is intended to allow a traveler to internally charge 3 AC powered devices and 4 USB compatible devices. To bring power to the distribution system the backpack has a 114 inch extension cord built into the frame of the backpack.  Aiding in locking the cable is an external 3 prong outlet intended to allow the pack owner to share electricity with others.

         As this is a concept design, the backpack emphasizes flexibility over such silly constraints as reasonable weight and pack size.  The large brick at the bottom of the design is a stand-in volume to represent a multipurpose power supply, containing a battery for supplying power to the USB ports, a DC to AC adapter (intended to plug into a car electric outlet), and an AC to AC converter, to ensure the user can power their devices anywhere on the planet.
