wherein the power bank assembly is configured to pass data received from the mobile device through the first electrical interface to the accessory device through the second electrical interface.
2 . The power bank assembly of claim 1 wherein the power bank assembly is configured to pass additional data received from the accessory device through the second electrical interface to the mobile device through the first electrical interface.
3 . The power bank assembly of claim 1 wherein the data includes video data displayed by the accessory device.
4 . The power bank assembly of claim 1 wherein the processor is further configured to receive charging information indicative of whether the battery is being charged by an external power source, the processor being configured to allow power from the battery to be simultaneously distributed to both the mobile device and the accessory device when the charging information indicates the battery is being charged by the external power source.
5 . The power bank assembly of claim 1 further including a third electrical interface configured for connection to an external power source for charging the battery.
6 . The power bank assembly of claim 1 further including a receiver coil and a wireless charging circuit for wirelessly receiving power from an external source, the wireless charging circuit being electrically connected to the battery.
7 . The power bank assembly of claim 6 further including a third electrical interface configured for connection to an additional external power source for charging the battery.
8 . The power bank assembly of claim 1 wherein the processor is further configured to receive charging information indicative of whether the battery is being charged by an external power source, the processor being configured to divert distribution of power provided by the battery from the mobile device to the accessory device when the charging information indicates the battery is not being charged by the external power source.
9 . The power bank assembly of claim 1 wherein the data received from the mobile device is provided by an application executing on the mobile device.
10 . The power bank assembly of claim 1 wherein the first electrical interface is a first USB-C connection and the second electrical connection is a second USB-C interface, the power bank assembly further including a third USB-C connection configured for connection to an external power source.
11 . A method performed by a power bank assembly having a first electrical interface configured for connection to a mobile device, a second electrical interface configured for connection to an accessory device intended for use with the mobile device and a battery connected to the first electrical interface and the second electrical interface, the method comprising:
receiving connection information indicating whether the mobile device is connected to the first electrical interface and whether the accessory device is connected to the second electrical interface;
selectively distributing power from the battery to one or both of the mobile device and the accessory device based at least in part upon the connection information; and
passing data received from the mobile device through the first electrical interface to the accessory device through the second electrical interface.
12 . The method of claim 11 further including passing additional data received from the accessory device through the second electrical interface to the mobile device through the first electrical interface.
13 . The method of claim 11 wherein the data includes video data displayed by the accessory device.
14 . The method of claim 11 further including:
receiving charging information indicative of whether the battery is being charged by an external power source;
simultaneously distributing power from the battery to both the mobile device and the accessory device when the charging information indicates the battery is being charged by the external power source.
15 . The method of claim 11 further including receiving, through a third electrical interface configured for connection to an external power source, power for charging the battery.
16 . The method of claim 11 further including wirelessly receiving power from an external source and providing the power to the battery.
17 . The method of claim 11 further including:
receiving charging information indicative of whether the battery is being charged by an external power source;
diverting distribution of power provided by the battery from the mobile device to the accessory device when the charging information indicates the battery is not being charged by the external power source.
