And for Apple products, it’s as good as any charger on our list. Finally, tech companies can work to offset their excesses in one area with savings in another. There are many ways tech companies could be more energy-efficient to put less strain on our power grids. Until wireless charging itself gets a more thorough examination, though, the world would probably be better off if we all stuck to good old-fashioned plugs. There are some things that companies can do to balance out the excess power wireless chargers use. They can also continue to offer wired charging, which might mean Apple’s rumored future port-less phone would have to wait.

In one inductive charging system, one winding is attached to the underside of the car, and the other stays on the floor of the garage. An inductive charging proponent from Toyota contended in 1998 that overall cost differences were minimal, while a conductive charging proponent from Ford contended that conductive charging was more cost efficient. September 2015 AUDI Wireless Charging presented a 3.6 kW inductive charger during the 66th International Motor Show 2015. In 2006, researchers at the Massachusetts Institute of Technology reported that they had discovered an efficient way to transfer power between coils separated by a few meters. The team, led by Marin Soljačić, theorized that they could extend the distance between the coils by adding resonance to the equation. The MIT inductive power project, called WiTricity, uses a curved coil and capacitive plates. Transcutaneous Energy Transfer systems in artificial hearts and other surgically implanted devices.
