Lachman said his RF wireless charging technology differs from others in that it will be more natural for users to simply drop an object, such as a hearing aid or a smartphone into a bowl rather than having to place it on a pad in a precisely oriented manner.
However, many of today's electromagnetic charging technologies allow for "loose coupling" of devices, so that an enabled mobile device simply needs to placed within a specified perimeter -- say, on a desktop surface, for example.
However, Mushnell believes wireless charging is pointless in the home, where wired charging is just as simple. "If I'm in my home, I can happily plug in. It's when I'm traveling that I may want to use a charging pad," he said.
Lachman disagreed, saying his NEST prototype allows multiple devices to charge at the same time without dealing with wires. "Obviously, the IP is not around putting things in box, but being able to transmitting RF in a controlled way to any number of devices," he said.
