According to Ossia, the chargers are completely safe for humans, even if there are multiple Cota chargers around. The power passed wirelessly by the transmitter will actively avoid any obstacles, including humans.

"Avoiding humans," lol. That's an amusing way to put it and tone down panic. What it really means is if the evil beam of energy can't tunnel through your body, it will beam-form to find a path of less resistance so you only get splash damage. Wear a tinfoil hat for better protection.

Yeah, I don't get how all those beam-forming variants manage to gloss over the fact that while beam-forming does create maxima at the target locations, it still spews more or less strongly correlated power everywhere else. How how much total transmitter power do you need to deliver 5W into a load 20' away? Even 50W is probably still very optimistic.

This is true wireless charging and the kind that I want. To fix the human factor, the device should be designed to be installed at a ceiling and should transmit at a lower power. See, as the writer mentioned already, charging time/speed is not a concern as it is always charging.
