Mobile to mobile wireless charging
First Claim
1. A first device comprising:
- a display;
a processor coupled with the display;
a memory system coupled with the processor;
wireless communication hardware coupled with the memory system and the processor;
a battery coupled with the display, the processor, the memory system and the wireless communication hardware;
a coil; and
wireless charging circuitry coupled between the coil and the battery,wherein the wireless charging circuitry is configured to charge the battery using power received wirelessly through the coil,wherein the wireless charging circuitry is further configured to draw power from the battery and operate the coil to wirelessly transmit the power from the battery to a second device,wherein the memory system encodes instructions for the processor, the instructions are configured to,present a user interface on the display,receive an input through the user interface that indicates an amount of power to provide to the second device,monitor power drawn from the battery during operation of the coil to wirelessly transmit the power from the battery to the second device, andterminate the wireless power transmission to the second device when the indicated amount of power has been provided, andwherein the instructions encoded in the memory system are configured to cause the processor to;
receive an input that specifies two or more charge amounts for two or more second devices; and
store the input that specifies the two or more charge amounts for later use when respective ones of the two or more second devices are paired with the processor.
