It costs $1250 for something with terrible efficiency. You could buy an awful lot of batteries for that much money.

Last time I read about this about 2/3 of the energy of the laser disappeared during the conversion to electricity. Has that improved?
Mor says Wi-Charge’s wireless power transfer efficiency is about 15 percent compared to a direct wired connection.
That’s not counting the energy used to power the transmitter’s Wi-Fi connection, status LEDs, and so forth.
Smart lock sounds insecure on multiple levels.

“Today I’ll be looking at this smart lock which is powered by a laser. All I’ll do is put a cover over it and wait…
And there we go.”
Seriously though, look up any “smart” lock on his channel. It’s hilarious how bad they all are.
They all have a backup method of opening, every time it's a cheap lock that is easy to open. It's obvious that all the companies are only interested in their digital idea, and not actual security.
Why does the lock, faucet and shades run on batteries to begin with? They aren't portable devices, just spend a few minutes running a damn cable and you never have to care about power ever again.
The coolest thing about this IR laser is the very cyberpunk things a hacker might do with it.
