It kind of makes sense that Tesla would make wireless chargers. After all, when you think of the company, you think electric vehicles and their Superchargers (at least, after you force the image of Elon Musk out of your mind). But wireless charging is a slightly different beast that requires understanding of magnetic fields and expertise in power transfer technologies. That’s where Freepower, formerly known as Aira, comes in. Founder Jake Slatnick started the company in 2017 and told Engadget that it has spent the last five and a half years developing a “much more advanced form of Qi,” the industry-wide standard for wireless charging.
