1. A method of delivering a power supply to a plurality of portable computing devices, comprising:
- determining by a central power device respective power requirements of the plurality of portable computing devices connected to the central power device, wherein;
a plurality of cables connect the plurality of portable computing devices and the central power device in a daisy chain configuration,the daisy chain configuration comprises a first device of the plurality of portable computing devices, and one or more downstream devices of the plurality of portable computing devices that are connected downstream of the first device in the daisy chain configuration,the first device is directly connected to the central power device,the one or more downstream devices are indirectly connected to the central power device via the first device, andthe power requirements include voltage information;
sending by the central power device, via one or more of the plurality of cables, information specifying an amount of power that the first device is to accept;
supplying power, based on the respective power requirements of the plurality of portable computing devices, from the central power device to the plurality of portable computing devices in the daisy chain configuration via the plurality of cables; and
passing through by the first device an excess amount of the power to the one or more downstream devices based on the information sent by the central power device.
