Abstract: A charging device is configured to deliver power to a portable, power-consuming device, having a profile sensor which can detect information relating to the identity of power-consuming device to which the charging device is connected and may also have a communication channel configured to transmit said information to a remote server. In use, data can be collected or aggregated relating to power-consuming devices by connecting the charging device to the portable power-consuming device; sensing, by a profile sensor in the charging device, information relating to the identity of the power-consuming device; and transmitting the information to a remote server over a communication channel. Collected data may, for example, be used to identify when fuel for a charging device may need replenishment.

Abstract: A power supply apparatus for providing electrical power, the power supply apparatus configured to be coupled to an electronic device to supply power thereto to charge a battery of the electronic device, the apparatus comprising a fuel cell configured to receive a supply of a fuel for generating said electrical power, the apparatus further including a controller configured to determine the power flow to the electronic device to interrupt the supply of power to the electronic device prior to the battery of the electronic device reaching a fully charged state.
