Wake from OFF state devices may be used to automate the otherwise tedious process of turning on a power switch. A wake from OFF state device is distinguished from a wake from sleep state device which continues to consume some amount of power to operate in a standby mode. A wake from OFF state power adapter can be turned fully off and left off indefinitely. There are no active standby circuits, no power consumption, no active logic, no emissions, no heat, when the device is in this OFF state. Wake from OFF state is useful for a variety of devices including (but not limited to) smartphones, portable computers, power tools, electric vehicles, and rechargeable batteries. ## Claims ### Claim 1 A wake from off state power adapter system comprising: a first connection device; a wake reset device connected to said first connection device; a wake from off state controller device connected to said wake reset device and said first connection device; a power processing device connected to said wake reset device; a power switching device connected to said wake from off state controller device and said power processing device; a second connection device connected to said power switching device; wherein when the power switching device is off, no power from the second connection device is consumed by the wake from off state power adapter system; wherein the wake from off state controller device receives power from an external device attached to the first connection device to initiate waking the wake from off state power adapter system from an off state; wherein the wake from off state controller device uses the received power to turn on the power switching device; wherein when the power switching device is on, power from an external power source attached to the second connection device can be configured by the power processing device to be used by the wake from off state power adapter system and the first connection device. ### Claim 2 (depends on 1) The system of claim 1, wherein the wake from off state controller device consists of a normally closed switch device, wherein said normally closed switching device is a shorted switch when there is no power or signal to explicitly establish that the switch is either open or closed, and a regulator device;
