#Handy New Wireless Charger Can Simultaneously Power 30 Mobile Phones at Distance.
Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing.
An effective wireless transmitting power of 30 watts means the device can, according to the researchers, power either 30 smartphones or five laptops simultaneously.
The results were published in last month’s issue of the journal IEEE Transactions on Power Electronics, and a spinoff company is now conducting pilot studies to apply this technology in cafes and offices.
