Some electric device

This morning, after waking up, I went to visit a cousin's house in our village. His house has Wi-Fi, so I connected to it and used it for a while.

After some time, the electricity went out, and I asked him, "Brother, how is your Wi-Fi still working after the power went out?" He told me that he has a UPS installed, which allows the Wi-Fi to run even during power outages. It mainly works through a battery and circuit system.

He explained more details about the UPS to me, and I found it very impressive. I took a few pictures of it and shared them with you all.
