Abstract: An electronics device carrier for porting a battery powered electronic device is formed by outer walls surrounding a hollow volume. The electronic device is held within the hollow volume and can be operated without removing the electronic device from the carrier. An input interface comprising interface elements external to the outer walls provides an element suitable for interfacing with external power devices such as a power source or another power load. A device interface includes interface elements at least partially disposed internal to the outer walls for interfacing with the electronic device battery. A charge controller is disposed between the input interface and the device interface and is operable to connect elements connected to the input interface to the device battery to either recharge the device battery or use the device battery as a power source.

Abstract: Various aspects of invention provide portable power manager operating methods. One aspect of the invention provides a method for operating a power manager having a plurality of device ports for connecting with external power devices and a power bus for connecting with each device port. The method includes: disconnecting each device port from the power bus when no external power device is connected to the device port; accessing information from newly connected external power devices; determining if the newly connected external power devices can be connected to the power bus without power conversion; if not, determining if the newly connected external power devices can be connected to the power bus over an available power converter; and if so, configuring the available power converter for suitable power conversion.

Abstract: A portable DC power manager (400) includes an internal power bus (410) and a plurality of device ports (1150, 1160, 1170, 1180, 1190, 1200) for connecting with external power and energy sources, external power loads and other external power managers. Each device port is isolated for the internal power bus by controllable switches (A, B, C, D). Power converters (440, 442, 510) may be disposed between device ports and the internal power bus to convert voltages and attenuate current amplitude. Energy management schema operating on the power manager sums available power and allocates the available power to connected power loads according to power priority settings. A hot-change-over circuit (1300) connects additional sources to the internal bus in response to a voltage drop on the internal power bus. A compact and lightweight package (1100) enables a portability.
