Abstract: A detachable tip, utilized with a power adapter, includes a memory, a receiver, and a transmitter. The memory stores a character string, the character string identifying whether an approved power adapter is coupled to the detachable tip. The receiver receives an identification request from an electronic device. In response to the identification request, a transmitter transmits the stored character string to the electronic device. A controller may extract the character string from the memory and send the character string to the transmitter. Instead of a character string, the memory may store a value, which is representative of a maximum power output available. A detachable tip may include an input connector and an output connector. The input connector receives a value from the power adapter, the value being representative of a maximum power available from the power adapter. The output connector passes through the value to the electronic device.

Abstract: Key coded power connectors include a single common power connector coupled to a power supply and a plurality of mating power connectors. A mating power connector is for coupling between the power connector and an electronic device. A mating power connector has a power rating based on the power drawn by a corresponding electronic device. The power connector has a power rating based on the power rating of the power supply. The connectors are shaped as a function of power rating such that only mating power connectors having a power rating equal to or less than the power rating of the power connector can be coupled together. This prevents an electronic device from being coupled to a power supply which cannot supply sufficient power to the electronic device.

Abstract: A key coded power connector and a system and method for making key coded power connections are disclosed. A power connector such as a power adapter connector is configured with either a visual keying system, a physical keying system, or both. The physical keying system prevents a user from connecting a host device to a connector of the power source which does not support that host device. The visual keying system provides the user with an early indication that the particular device is not supported by a power source. The user can visually compare a marking key on the host device with the making key on the power connector and determine whether or not the power source is capable of outputting sufficient power to operate the device. The visual and physical keying systems prevents a user from improperly connecting a host device to a power source which does not support that device.
