I&#x27;m still extremely skeptical about this. The inverse square law is a huge hurdle, power delivery rate has got to be minuscule.<p>This isn&#x27;t making a better charger, it&#x27;s making better physics.

No idea about speed of charge. That&#x27;s what the game is right now. I used to have a phone with wireless charging but it was way slower than using the wired smart charger (the one with the tech from Qualcomm)

On one hand, it&#x27;s crazy that they pulled this off, of the other hand, I&#x27;m not sure if I see the practical applications of near-range wireless line-of-sight charging
