Claims

1. An attachable battery pack, comprising

a body configured to fit the screen of an intelligent cell phone and carrying therein a Li-polymer battery cell and a charging circuit, said body having opposing front and back side and opposing first and second ends, a static flocking fabric covering at said front side, a genuine leather covering at said back side and a springy hook extended from said first end;

a clamp pivotally connected to the second end of said body and adapted for clamping to one end of an intelligent cell phone for enabling said body to be biased relative to the intelligent cell phone between an open position where said body is kept away from the intelligent cell phone and a close position where said spring hook of said body is hooked on an opposite end of the intelligent cell phone;

an electrical connector fixedly located on said clamp and electrically connected said Li-polymer battery cell and said charging circuit of said body;

a power switch located on one of two opposing lateral sides of said body and operable to switch on/off electric connection between said electrical connector and said Li-polymer battery cell and said charging circuit of said body;

a power jack located on one of the two opposing lateral sides of said body for the connection of a charging cable to charge said Li-polymer battery cell of said body with an external power source; and

an indicator light located on one of the two opposing lateral sides of said body and adapted for giving off light when said power switch is switched on.
