1. A method executable by a power-consuming device, the method comprising:
- receiving a light beam from a charging device via a photovoltaic cell of the power-consuming device;
in response to receiving the light beam, activating a power monitoring unit of the power-consuming device, wherein the power monitoring unit determines a power level of a rechargeable power unit of the power-consuming device, wherein the power monitoring unit is activated in part by receiving power from the charging device;
contactlessly and wirelessly signaling, by the power monitoring unit, the power level to the charging device, the signaling enabling the charging device to determine a status of the power level of the power-consuming device that indicates an ability of the power-consuming device to accept power from the charging device;
after signaling the power level to the charging device, receiving another light beam from the charging device;
generating power using energy received from the other light beam using the photovoltaic cell; and
charging a battery of the power-consuming device using the generated power.

Abstract
Techniques for facilitating wireless charging are discussed herein. For example, a power-consuming device may receive a light beam from a charging device. In response, the power-consuming device may determine a power level of a battery associated with the power-consuming device. The power-consuming device may wirelessly signal the power level to the charging device. In some instances, the power-consuming device may determine the power level of the battery without drawing power from the battery. Further, in some instances the power-consuming device may receive another light beam to charge the battery.
