Abstract

A power cable for an electronic device. Implementations may include a serial communication plug and one or more battery adaptors that each include a core including an electrical insulator where the core is coupled at a first end to a positive terminal and at a second end to a negative terminal. The positive terminal may be coupled to a diode coupled to the serial communication plug to which the negative terminal may be coupled. The one or more battery adaptors may be each configured to couple within one or more battery compartments included in an electronic device. The electronic device may receive power from the serial communication plug through the one or more battery adaptors when the one or more battery adaptors are coupled within the one or more battery compartments and when the serial communication plug is coupled within a serial communication receptacle of another electronic device.

Claims

1. A power cable for an electronic device comprising:

a serial communication plug; and

two battery adaptors each comprising;

a core comprising an electrical insulator, the core having a first end and a second end;

a positive terminal coupled to the first end of the core, the positive terminal comprising a cylindrical projection extending from a center of the positive terminal; and

a negative terminal coupled to the second end of the core;

wherein the positive terminals of the two battery adaptors are connected in parallel with a diode coupled to the serial communication plug and the negative terminals are coupled in parallel with the serial communication plug;

wherein the two battery adaptors are each configured to couple within two battery compartments included in the electronic device; and

wherein the electronic device is configured to use three batteries and the two battery adaptors are configured to supply electrical power for the electronic device when the two battery adaptors are coupled within two of three battery compartments included in the electronic device and when the serial communication plug is coupled within a serial communication receptacle of another electronic device.
