1. A power storage adapter (PSA), comprising:
- a housing including a first surface and a second surface opposite the first surface;
a PSA port;
a PSA battery;
a first wireless power unit including a first transmitter, a first receiver, a first coil in proximity to the first surface, and a first proximity sensor;
a second wireless power unit including a second transmitter, a second receiver, a second coil in proximity to the second surface, and a second proximity sensor;
a first magnetic shield to divert a first magnetic flux of the first coil away from the second coil and to generate a first opposing magnetic flux to remove effects of the first magnetic flux on the second coil;
a second magnetic shield to divert a second magnetic flux of the second coil away from the first coil and to generate a second opposing magnetic flux to remove effects of the second magnetic flux on the first coil;
a communication device; and
a PSA controller having access to memory media storing instructions executable by the PSA controller to;
detect a first electronic device having a third coil at one of the first surface and the second surface using the first proximity sensor and the second proximity sensor;
determine, using the communication device, whether the first electronic device is enabled to receive or transmit wireless power;
when the first electronic device is enabled to transmit the wireless power, receive a first wireless power from the third coil at one of the first surface and the second surface based on the first proximity sensor and the second proximity sensor; and
when the first electronic device is enabled to receive the wireless power, transmit the first wireless power to the third coil at one of the first surface and the second surface based on the first proximity sensor and the second proximity sensor.

Abstract
A power storage adapter may include wireless power units for wireless power transmission of multiple portable information handling systems. In particular, when a wireless power unit wirelessly transmits a first wireless power to one of the portable information handling systems, another wireless power unit may wirelessly transmit a second wireless power to another portable information handling system. The transmission of the first wireless power may be simultaneous with the transmission of the second wireless power.

10. A method, comprising:
-
detecting a first electronic device having a third coil at one of a first surface and a second surface of a housing of a power storage adapter using a first proximity sensor and a second proximity sensor of the power storage adapter, the power storage adapter including a first coil in proximity to the first surface and a second coil in proximity to the second surface, wherein the second surface opposite the first surface; determining, using a communication device of the power storage adapter, whether the first electronic device is enabled to receive or transmit wireless power; when the first electronic device is enabled to transmit the wireless power, receiving a first wireless power from the third coil at one of the first surface and the second surface based on the first proximity sensor and the second proximity sensor; when the first electronic device is enabled to receive the wireless power, transmitting the first wireless power to the third coil at one of the first surface and the second surface based on the first proximity sensor and the second proximity sensor; diverting, by a first magnetic shield of the power storage adapter, a first magnetic flux of the first coil away from the second coil; generating, by the first magnetic shield of the power storage adapter, a first opposing magnetic flux to remove effects of the first magnetic flux on the second coil; diverting, by a second magnetic shield of the power storage adapter, a second magnetic flux of the second coil away from the first coil; and generating, by the second magnetic shield of the power storage adapter, a second opposing magnetic flux to remove effects of the second magnetic flux on the first coil. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
