How to physically reboot a computer remotely?

Question

Computers

The question is next.
The computer is in a friend's office 4,000 kilometers from me. The application I need is running on it, I follow its work through the teamviewer. But the problem is that the application hangs hard with an enviable frequency. Can't reach through teamviewer. And then I ask a friend to physically restart the computer.
But people are in the office a maximum of 12 hours a day, and I sometimes have to wait more than 10 hours before rebooting. And the application is quite critical ...
Therefore, we need the ability to remotely hard reboot the computer . How?
Desirable solution than cheaper, up to 30 bucks.
PS: A wireless Wi-Fi socket came to mind today (for example, Orvibo s20 or Xiaomi Mi). The plan is this - through the Internet, I can physically cut down the computer's power from here, and then turn it on. The computer is configured to auto-boot on power-up. Well, I get a remote reboot. Who thinks it will work?
