A wireless-power receiver is disclosed including a first antenna configured to transmit first near-field radio frequency (RF) energy, a second antenna configured to receive second near-field RF energy, and a communications component configured to provide a communication signal including data indicating a location of the first wireless-power receiver. The wireless-power receiver is configured to, in accordance with a determination that the wireless-power receiver is in direct contact with a surface of another wireless-power receiver, transmit the first near-field RF energy, via the first antenna, to the other receiver. The wireless-power receiver is further configured to, in accordance with a determination, based on the data indicating the location of the wireless-power receiver, that the wireless-power receiver is within a non-zero threshold distance from the other receiver or a wireless-power transmitter, receive the second near-field RF energy, via the second antenna, from the other receiver or from the wireless-power transmitter.
