1. An adapter comprises:
- a first member including appropriate mating fittings disposed on a common surface of the first member;
a second member housing electronics to convert power incident at an input of the adapter to an output power level at the appropriate mating fittings of the first member; and
a first pair of wires coupled between an input of the first member and output of the second member; and
a second pair of wires coupled from an input of the second member to an electronic plug.

Abstract
A hybrid power supply includes a fuel cell and an interface between the fuel cell and a fuel cartridge or external battery and a switching type DC/DC boost type converter that receives energy from the fuel cell or external battery and is arranged to deliver the energy to a rechargeable cell. The hybrid power supply also includes a fuel cell current sensor/comparator, included in a feedback control loop disposed about the DC/DC converter, which controls in part operation of the converter to provide constant current discharge on the fuel battery side of the hybrid power supply. An adapter that couples a source of AC power such as a charger to the interconnect is also disclosed.

6. A hybrid power supply, comprising:
-
an interconnect including appropriate mating fittings on a common planar surface to allow the interconnect to connect to either a battery, or a source of fuel for a fuel cell system or an adaptor; an adapter comprises; a first member including appropriate mating fittings disposed on a common surface of the first member to allow the first member to connect to the interconnect on the hybrid power supply; a second member housing electronics to convert power incident at an input of the adapter to an output power level at the appropriate mating fittings of the first member; and a first pair of wires coupled between an input of the first member and output of the second member; and a second pair of wires coupled from an input of the second member to an electronic plug; and a switching type DC/DC boost type converter coupled to the interconnect and which receives energy from a fuel cell or from an external battery connected to the interconnect, and which is arranged to deliver the energy to a rechargeable cell, the DC/DC converter configured to provide substantially constant current drain from the fuel cell. - View Dependent Claims (7, 8, 9, 10)
