1. An apparatus for providing power to a portable electronic device (PED, including:
a first housing, the first housing mechanically separatably from the PED, the first housing substantially including a first power interface module (PIM), the first PIM including at least two electrical contacts configured to be releasably and directly coupled with the PED, the PIM at least two electrical contacts configured to provide a power signal having a first and a second polarity; and a second housing, the second housing physically separate from the PED and coupled to the first housing via a substantially flat, flexible cable, the second housing including an external power source interface (EPSI), the (EPSI) including at least two separate electrical contacts configured to receive electrical signals having the first and the second polarity, and a converter module coupled to the EPSI, the converter module converting a signal from the EPSI having a first voltage level to a signal having a lower, second voltage level; the substantially flat, flexible cable fixably coupling the first housing to the second housing and including at least one wire pair, the wire pair coupling the first housing first PIM at least two electrical contacts to the second housing converter module to provide the signal having the lower, second voltage level to the first PIM at least two electrical contacts. |
