The RCA_airnergy is a USB-connected device that converts Wi-Fi antenna signals into usable power for your gadgets. The device is completely self-sustaining — it automatically charges whenever a Wi-Fi signal is close by and stores the power in a lithium-ion battery. While it may not be practical for emergency charging in the woods, the Airnergy could be invaluable in on-the-go situations when your cell phone’s power is petering out.
