## Abstract

According to one disclosed embodiment, a smart power delivery system includes a power conversion unit having a communication module and a power management module that can convert mains power into an optimized voltage and limited current used to power an electronic device. In one embodiment, a power conversion unit can optimize an output voltage by communicating with a connected electronic device and exchanging parameters representing desired characteristics of the output voltage. In one embodiment, an electronic device receives power from a power conversion unit through a wired power conduit. In another embodiment, an electronic device receives power from a power conversion unit through a wireless power conduit. In one embodiment, an optimal voltage is selected after negotiation between multiple electronic devices and a power conversion unit.

## Claims

### Claim 1

An electronic device configured to deliver power, comprising:
a first circuit configured to connect a power source to a second electronic device via a first power delivery conduit;
a second circuit configured to connect the power source to a third electronic device via a second power delivery conduit, the first power delivery conduit being configured to deliver power to the second electronic device in parallel with the second power delivery conduit delivering power to the third electronic device;
circuitry configured to exchange information with the second electronic device and the third electronic device, wherein the information includes an indication of respective device power requirements; and
a power management module (PMM) configured to manage power delivery to the respective electronic devices, wherein
based on the indication of respective device power requirements, the PMM is configured to manage delivery of power to the second electronic device and the third electronic device by partitioning and dynamically applying the power on a per conduit basis across the first power delivery conduit and the second power delivery conduit, wherein
the PMM is configured to deliver power on at least one of a first-come-first-served basis, a programmed prioritization basis, a quickest time to charge basis, or an equal current partition basis.

### Claim 2 (depends on 1)

The electronic device of claim 4, wherein
the wired conduit includes a USB interface plug-in connector.

### Claim 9 (depends on 1)

The electronic device of claim 1, wherein the PMM is configured to partition the power delivered to the respective power delivery conduits to match substantially different power requirements of the second electronic device and third electronic device.

### Claim 10 (depends on 1)

The electronic device of claim 1, further comprising
an electrical interface configured to receive power from the power source.

### Claim 11

A method for delivering power from an electronic device, comprising:
conveying power from a power source through a first circuit connected to a second electronic device via a first power delivery conduit;
conveying power from the power source through a second circuit connected to a third electronic device via a second power delivery conduit, the first power delivery conduit being configured to deliver power to the second electronic device in parallel with the second power delivery conduit delivering power to the third electronic device;
exchanging first information with a second electronic device via a first power delivery conduit, the first information including an indication of device power requirements of the second electronic device;
exchanging second information with a third electronic device via a second power delivery conduit, the second information that including an indication of device power requirements of the second electronic device; and
managing with a power management module (PMM) power delivery to the respective electronic devices, wherein
based on the indication of respective device power requirements, the managing further comprising partitioning and dynamically applying the electric power on a per conduit basis across the first power delivery conduit and the second power delivery conduit, wherein
the managing further comprises delivering power on at least one of a first-come-first-served basis, a programmed prioritization basis, a quickest time to charge basis, or an equal current partition basis.

### Claim 12 (depends on 11)
