Mobile device finger support apparatus

A finger support apparatus for a handheld computing device of a type that includes a case having one of a battery port or an accessory port in electrical communication with a computing device battery and having a lower frame portion, said finger support apparatus, comprising:

• a mounting portion having an inlet plug configured for insertion into the accessory port of the handheld computing device, said mounting portion having a fixed configuration that defines a longitudinal axis extending longitudinally away from the handheld computing device;
• a body portion coupled to the mounting portion and extending away from the lower frame portion, said body portion being configured to rotate axially about said longitudinal axis;
• wherein said body portion includes a proximal edge adjacent said mounting portion, a distal edge opposite said proximal edge, and a pair of laterally opposed side edges extending between said proximal and distal edges, said proximal, distal, and pair of side edges together defining an interior area;
• an auxiliary battery mounted in said interior area of said body portion, said auxiliary battery having an electrical charge and is electrically coupled to said inlet plug of said mounting portion such that said electrical charge is transferred to the computing device battery;
• and
• a charging cap that defines a chamber and includes electrical storage media that is positioned in said chamber for storing electrical current, said charging cap having a charging port that is dimensioned to receive said inlet plug of said mounting portion such that said stored electrical current is transferred to said auxiliary battery.
