The system can analyze any input voltage to determine whether the input voltage is sufficient to charge the battery of an electronic device and/or to operate the electronic device. If not, the cable is capable of transforming the input voltage to a voltage sufficient to charge and/or operate. The electronic device may be incorporated into the housing of the smart electronic system, and can be any known mobile devices. ## Claims ### Claim 1 An electronic system comprising: an analyzing assembly electrically connected to an energy storage device disposed within a housing of the electronic system, wherein the analyzing assembly includes: a voltage analyzing circuit to analyze a first voltage supplied by the energy storage device; at least one electrical converter to transform the first voltage to a second voltage sufficient to charge a battery of an electronic device or to power the electronic device, a bypass circuit; and an under voltage lock out device; wherein when the first voltage is sufficient to charge the battery or to power the electronic device the first voltage is directed to the bypass circuit to charge the battery or to power the electronic device, wherein when the first voltage is not sufficient to charge the battery or to power the electronic device the first voltage is transformed to the second voltage by the at least one electrical converter to charge the battery or to power the electronic device, and wherein the under voltage lock out device shuts down the electronic device when the first voltage falls below operating voltage of the electronic device, or shuts down the electronic system when the first voltage falls below a predetermined level. ### Claim 2 (depends on 1) The electronic system of claim 1, wherein the at least one electrical converter comprises a DC/DC converter. ### Claim 3 (depends on 2) The electronic system of claim 2, wherein the DC/DC converter is a step-up converter. ### Claim 4 (depends on 2) The electronic system of claim 2, wherein the DC/DC converter is a step-down converter. ### Claim 5 (depends on 1) The electronic system of claim 1, wherein the at least one electrical converter comprises an AC/DC converter. ### Claim 6 (depends on 1) The electronic system of claim 1 further comprises a state of charge indicator. ### Claim 7 (depends on 6) The electronic system of claim 6 further comprises an operating switch connected to the state of charge indicator. ### Claim 8 (depends on 1) The electronic system of claim 1, wherein the energy storage device comprises mother battery or a capacitor. ### Claim 9 (depends on 1) The electronic system of claim 1, wherein the electronic device is contained in the housing. ### Claim 10 (depends on 1) The electronic system of claim 1, wherein the electronic device comprises a lighter. ### Claim 11 (depends on 10) The electronic system of claim 10, wherein the lighter comprises an arc lighter. ### Claim 12 (depends on 10) The electronic system of claim 10, wherein the lighter comprises a heating element. ### Claim 13 An electronic device comprising: an analyzing assembly electrically connected to an energy storage device, wherein the analyzing assembly includes: a voltage analyzing circuit to analyze a first voltage supplied by the energy storage device; at least one electrical converter to transform the first voltage to a second voltage sufficient to power the electronic device; a bypass circuit; and an under voltage lock out device; wherein when the first voltage is sufficient to power the electronic device the first voltage is directed to the bypass circuit to power the electronic device, wherein when the first voltage is not sufficient to power the electronic device the first voltage is transformed to the second voltage by the at least one electrical converter to power the electronic device, and wherein the under voltage lock out device shuts down the electronic device when the first voltage falls below operating voltage of the electronic device, or shuts down the electronic device when the first voltage falls below a predetermined level. ### Claim 14 (depends on 13) The electronic system of claim 13, wherein the at least one electrical converter comprises a DC/DC converter. ### Claim 15 (depends on 14) The electronic system of claim 14, wherein the DC/DC converter is a step-up converter. ### Claim 16 (depends on 14) The electronic system of claim 14, wherein the DC/DC converter is a step-down converter. ### Claim 17 (depends on 13) The electronic system of claim 13, wherein the at least one electrical converter comprises an AC/DC converter. ### Claim 18 (depends on 13) The electronic system of claim 13, wherein the electronic device comprises a lighter. ### Claim 19 (depends on 18) The electronic system of claim 18, wherein the lighter comprises an arc lighter. ### Claim 20 (depends on 18) The electronic system of claim 18, wherein the lighter comprises a heating element.
