1. A power device for supplying power to a portable rechargeable electronic device, the power device comprising:
- a first portion for receiving electrical input power from a source, the input having an input voltage;
a second portion for delivering electrical output power to the electronic device, the output power having an output voltage;
a connector located on the second portion and removably connectable with the electronic device; and
a switch assembly located remote from the first portion, the switch assembly having a member movable to and between first and second positions corresponding to respective “
on” and
“
off”
states, wherein the power device receives the input power in the “
on”
state, and the power device draws no input power in the “
off”
state.

9. A power device for supplying power to a portable rechargeable electronic device, the power device comprising:
-
a first portion for receiving electrical input power from a source, the input having an input voltage; a second portion for delivering electrical output power to the electronic device, the output power having an output voltage; circuitry for converting the input power voltage to the output power voltage and for determining an “
off”
state of the circuitry;a connector located on the second portion and removably connectable with the electronic device; and a switch assembly having powered terminals, the switch assembly responsive to movement of at least a movable portion thereof to electrically connect the terminals and to provide an output signal to activate the circuitry to the “
on”
state,wherein the circuitry automatically turns the circuitry to the “
off”
state, the circuitry drawing no power when in the “
off”
state. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
