Mobile device charging apparatus including a mechanical wheel

A mobile device charging apparatus, comprising:

• a mobile device case including an electrical adapter configured to connect with a charging port of a mobile device;
• an access port in electrical communication with the electrical adapter;
• a mechanical wheel positioned in the mobile device case, the mechanical wheel in electrical communication with the electrical adapter;
• a torsion spring positioned within the mechanical wheel, the torsion configured to bias the mechanical wheel toward a starting position;
• a tether in communication with the mechanical wheel,
• wherein the tether is configured to translate a mechanical force to the mechanical wheel to generate electricity, and
• wherein the mechanical wheel is configured to provide an electrical current to the mobile device through the electrical adapter to charge the mobile device;
• and
• a crank indicator configured to indicate when the electrical current is being provided to the mobile device to charge the mobile device, wherein the crank indicator includes a plurality of lights indicating an amount of electrical energy that is being generated by the mechanical wheel.
