Wireless charging is set to truly hit the mainstream with the iPhone 8, but a startup named Pi wants to further extend the reach of the technology-- specifically by 30cm, through the imaginatively named Pi Charger.
As debuted at the TechCrunch Disrupt Battlefield event, the Pi Charger is a conical device able to charge multiple devices within around 30cm in any direction. It is not a full-room wireless charging offering, the the maker promises it actually works, and does so without need to put devices on a charging pad.
The technology behind the Pi Charger is resonant induction, the same used by the Qi standard found in the new iPhones. It is paired with a special beam forming algorithm allowing Pi to shape and direct the magnetic fields around the device. This allows users to charge a smartphone by putting it next to the charger, as opposed to directly on it.
