The second device couples to the power source apparatus. The power source provides status information to the first device. The first device sends a communication to the power source apparatus via an application operating on the first device, wherein the communication provides a charging instruction to the power source device and the instruction is based on the status information received from the power source. The power source apparatus charges the second device based on the charging instruction received at the power source apparatus from the first device. The server communicates with the first device to maintain a database relating to at least one of the power source apparatus and the second device and comprising status information. ## Claims ### Claim 1 A system comprising: a power source apparatus; a first device associated with a user; a second device associated with the user; and a server computer; wherein: the second device is configured to couple to the power source apparatus; wherein: the power source apparatus is configured to provide status information to the first device; the first device is configured to send a communication to the power source apparatus via an application operating on the first device, wherein the communication provides a charging instruction to the power source apparatus and the instruction is based on the status information received from the power source apparatus; the power source apparatus is configured to charge the second device based on the charging instruction received at the power source apparatus from the first device; and the server computer is configured to communicate with the first device to maintain a database relating to at least one of the power source apparatus and the second device and comprising status information. ### Claim 2 (depends on 1) The system of claim 1, wherein the first device is configured to provide, to the server computer, the status information of at least one of the power source apparatus and the second device, wherein the server computer is configured to process the status information and modify the operation of the application on the first device based on said processing. ### Claim 3 (depends on 2) The system of claim 2, wherein the first device is configured to request the second device for the status information and forward such information to the server computer. ### Claim 4 (depends on 2) The system of claim 2, wherein the first device is configured to request the power source apparatus for the status information and forward such information to the server computer. ### Claim 5 (depends on 1) The system of claim 1, wherein the application is configured to request access to another application running on the first device and wherein the communication sent to the power source apparatus from the first device is based on information obtained from the other application. ### Claim 6 (depends on 5) The system of claim 5, wherein the application is configured to transmit the information obtained from the other application to the server computer. ### Claim 7 (depends on 1) The system of claim 1, wherein the first device is configured to provide to the power source apparatus, via the application, a prioritisation for charging a plurality of devices and wherein the power source apparatus is configured to charge the plurality of devices based on the prioritisation and the prioritisation is configurable using the application. ### Claim 8 A power source apparatus comprising: a power source; a communications interface; a communications circuit; a charging circuit; and a plurality of charging points coupled to the charging circuit; wherein: each of the plurality of charging points is configured to couple to a respective user device to charge said device; the power source is configured to provide power to at least one of the charging points coupled to a user device; the communications interface is configured to transmit, to a first user device operating an application, a first communication comprising status information of the power source apparatus and receive, from the first user device, a second communication comprising a charging instruction for charging at least one of the user devices coupled to respective charging points, wherein the charging instruction is based on the status information received from the power source and the first user device transmits the status information to a server computer for incorporation into a database maintained by the server computer; the communications circuit is configured to forward the charging instruction to the charging circuit; and the charging circuit is configured to control the provision of power to the respective charging points by the power source based on the charging instruction. ### Claim 9 (depends on 8) The power source apparatus of claim 8, wherein at least one of the plurality of charging points is a DC charging port. ### Claim 10 (depends on 8) The power source apparatus of claim 8, wherein the power source is a first power source comprising a first power output level and the first power source is replaceable by a second power source comprising a second power output level different to the first power output level. ### Claim 11 (depends on 8) The power source apparatus of claim 8, wherein the charging circuit is configured to: determine a prioritisation between the first user device coupled to a charging point and a second user device coupled to another charging point based on a communication received at the power source apparatus from at least one of the first and second user devices; and charge the first and second user devices based on the determined prioritisation. ### Claim 12 (depends on 8) The power source apparatus of claim 8, wherein the power source is a first power source associated with a first level of power and is replaceable by a second power source associated with a second, different level of power, wherein the charging circuit is configured to control the provision of power based on which of the first and second power sources are inserted into the power source apparatus. ### Claim 13 A method of managing a charging system comprising a power source apparatus; a first device associated with a user and running an application; a second device associated with the user; and a server computer, the method comprising: sending, by the first device via the application, a charging instruction to the power source apparatus, wherein the charging instruction is based on a status of the second device; in response to the power source apparatus coupling to the second device and subsequently charging the second device according to the charging instruction, sending, by application, information relating to the second device to the server computer; and updating, by the server computer, a database relating to the second device based on the information.
