Abstract

Claims (58)

1. A method for controlling power delivery to an electronic device having proprietary and default power modes for power delivery, the method comprising the steps of:

connecting a power delivery adapter to the electronic device, wherein the electronic device is a portable loudspeaker having an amplifier and a rechargeable battery;

completing a power delivery protocol between the power delivery adapter and the electronic device;

delivering power to the electronic device according to the default power mode, wherein when power is delivered to the portable loudspeaker according to the default power mode, the amplifier only draws power from the battery;

requesting a proprietary protocol for the proprietary power mode from the electronic device;

when no proprietary protocol is communicated to the power delivery adapter, the power delivery adapter continues to deliver power to the electronic device according to the default power mode;

when the proprietary protocol is communicated to the power delivery adapter, the power delivery adapter makes a request to deliver the power to the electronic according to the proprietary power mode;

confirming the request to deliver power according to the proprietary power mode; and

delivering power to the electronic device according to the proprietary power mode, wherein when power is delivered to the portable loudspeaker according to the proprietary power mode, an amplifier in the portable loudspeaker draws power from the power delivery adapter.

2. The method of claim 1 , wherein the step of confirming the request to deliver power according to the proprietary power mode further comprises the steps of:

sending a power delivery mode identification to the power delivery adapter;

matching the power deliver mode identification with a power delivery identification stored in memory at the power delivery adapter;

sending the request to deliver power according to the proprietary power mode;

acknowledging, at the electronic device, the proprietary power mode; and

delivering power to the electronic device according to the proprietary power mode.

3. The method according to claim 1 , wherein the step of requesting the proprietary protocol further comprises the steps of:

communicating an identification code for the proprietary protocol;

verifying the identification code for the proprietary protocol matches an identification code stored in memory at the power delivery adapter.

4. The method according to claim 3 , wherein the step of verifying the identification code further comprises the steps of:

requesting a standard or vendor identification (SVID) from the electronic device;

sending the SVID to the power delivery adapter; and

matching the SVID with an SVID stored at the power delivery adapter.

5. The method of claim 1 wherein the power delivery adapter is a USB-C type connector.

6. The method according to claim 1 , further comprising;

the default power mode delivers a maximum voltage of 20V and a maximum current of 3A.

7. The method of claim 1 , further comprising:

the proprietary power mode delivers a maximum voltage of 20V and a maximum current of 4.5A.

8. A non-transitory computer-readable medium comprising a program, which when executed by one or more processors performs an operation comprising:

completing a power delivery protocol between a power delivery adapter and an electronic device having proprietary and default power modes;

delivering power to the electronic device according to a default power;

requesting a proprietary protocol for a proprietary power mode from the electronic device;

when no proprietary protocol is communicated to the power delivery adapter, the power delivery adapter continues to deliver power to the electronic device according to the default power mode;

when a proprietary protocol is communicated to the power delivery adapter, confirming the proprietary power mode; and

upon confirmation of the proprietary power mode, delivering power to the electronic device according to the proprietary power mode;

wherein, the electronic device has a rechargeable battery and an amplifier whereby, when power is delivered according to the default power mode, the amplifier only draws power from the battery;

wherein when power is delivered according to the proprietary power mode, the amplifier draws power from the power delivery adapter.

9. The non-transitory computer-readable medium of claim 8 , wherein confirming the proprietary power mode further comprises:

requesting a standard or vendor identification (SVID) from the electronic device;

confirming the SVID matches an SVID stored at the power delivery adapter; and

upon confirmation, delivering power to the electronic device according to the proprietary power mode.

10. The non-transitory computer-readable medium of claim 8 , wherein:

the proprietary power mode delivers a maximum voltage of 20V and a maximum current of 4.5A; and

the default power mode delivers a maximum voltage of 20V and a maximum current of 3A.

11. An electronic device comprising:

a battery;

an amplifier;

an interface that receives external power from a power delivery adapter;

a proprietary power delivery mode;

a default power delivery mode;

a processor configured to communicate the proprietary power delivery mode to the power delivery adapter;

when the power delivery adapter has a standard or vendor identification (SVID) that matches an SVID of the electronic device, the power delivery adapter delivers power according to the proprietary power delivery mode; and

when the power delivery adapter has an SVID that does not match an SVID of the electronic device, the power delivery adapter delivers power according to the default power delivery mode,

the electronic device is a portable loudspeaker having the amplifier and a rechargeable battery;

when power is delivered to the portable loudspeaker according to the default power delivery mode, the amplifier only draws power from the battery;

when power is delivered to the portable loudspeaker according to the proprietary power delivery mode, the amplifier draws power from the power delivery adapter.

12. The electronic device of claim 11 , wherein;

the default power mode delivers a maximum voltage of 20V and a maximum current of 3A; and

the proprietary power mode delivers a maximum voltage of 20V and a maximum current of 4.5A.
