Pi Claims It Can Charge Your Smartphone Wirelessly From A Distance

19 Septembre 2017

A new startup called Pi claims to have developed a product that allows for truly contactless wireless charging.

But instead of cords or mats, the conical creation charges smartphones with magnetic waves. The magnetic fields are are an ideal way to safely send energy to portable electronics. A combination of smartphones and tablets could wirelessly charge on a desk if a Pi were placed near people working together.MacDonald promised that Pi devices would begin shipping next year and be priced below $200.

According to media reports from the Agence France-Presse, Lixin Shi said that the magic was bending magnetic waves to find smartphones.

"The hard part was figuring out how to make magnetic charging more flexible, multi-device and extend its useful range", Shi said. "It took us over a year to complete the mathematical proof that makes it all possible".

One common issue seems to be that sent emails remain in the drafts folder and are not being delivered to recipients. The firm said it is redirecting requests to alternative infrastructure in an attempt to restore service.

The pair figured out how to shape the magnetic field so energy could be beamed to smartphones placed or in use within a foot of a Pi. Until now, existing wireless chargers required you to put the smartphone on top of them to be able to charge wirelessly.

The technology was demonstrated by the company co-founders, John Macdonald, CEO, and Lixin Shi, CTO, at a recent TechCrunch Disrupt event. It was also revealed that the Pi device could charge up to four devices simultaneously at full speed within the same range.

Pi set up shop in the Silicon Valley city of San Bruno, and the co-founders said they raised $3.5 million in a seed funding round lead by SoftTech VC managing partner Jean-Francois Clavier. He says that you can move the device in whatever direction around the Pi, and in different orientations, and it'll still work. These chargers use the standard charging technology, completely compliant with the way wireless Android and Apple smartphones are created to be charged.
