Samsung has plans to make its own advanced charging mat

Samsung is following Apple deeper into the wireless charging mat game. 

The site Patently Apple found Samsung's plans filed with the U.S. Patent and Trademark Office. The patent application shows a mat similar to Apple's forthcoming AirPower technology, which Apple says will become available sometime in 2018. 

Samsung already offers wireless charging technologies (one is pictured above), but they can only charge one device at a time.
