Researchers at the Korea Advanced Institute of Science and Technology (KAIST), have developed a wireless charging system that can charge around 40 smart phones at a time, from a distance of 5 meters (16 ft). While we've examined numerous wireless charging systems, even one that transmits power to up to 9 m (30 ft), KAIST's prototype can power multiple devices within its range. It can deliver enough electrical juice, the scientists claim, to power many larger devices like fans, TVs and computers, simultaneously.
