Wireless charging technology is in great demand all over the world, but all non-contact chargers still assume physical contact with smartphones, by placing them on a special stand. Indeed, the contactless method of charging mobile gadgets at a distance of 30 cm from the charging station was able create group of researchers, who merged in start-up Pi.
The appearance of the contactless charger is quite elegant and small in size the truncated cone, placing around which smartphones or tablets, users will be able to recharge the battery. The range of Pi Charger does not exceed 30 cm (12 inches). The principle of the innovative product is based on the technology of resonance induction with the formation of a beam directed toward the charged object.
By placing up to 4 mobile gadgets around the Pi Charger, users can recharge them with a maximum power of up to 10 watts. However, during the presentation, charging of four smartphones and one tablet was demonstrated. According to the inventors, the increase in the number of energy-powered devices reduces the efficiency and speed of such charging, although interaction with more than 4 devices is allowed
All mobile devices that support the Qi standard will be able to take advantage of the Pi Charger. Among such smartphones are Samsung Galaxy S8 / S8 Plus / Note 8, iPhone 8, iPhone 8 Plus and iPhone X. For gadgets that do not support Qi technology, are provided the special cases.
Startup Pi was created by immigrants from the laboratory of computer science at the Massachusetts Institute of Technology and Artificial Intelligence, otherwise known as CSAIL. Since MIT has strong traditions associated with number Pi (3.141592), the inventors decided to name their startup by the name of a known number.
