I was lying on my bed when the electricity suddenly went out, and I saw my DIY mini UPS that I had fitted inside an Amul ice cream box.

In the past, I used two UPS units for my internet setup, but both used to heat up too much. Within a year, one developed a battery issue and the other completely stopped working.

So, after doing some research on the internet and with the help of ChatGPT, I built this one — and it works like a charm. It cost me around ₹500–600 and gives me about 1 hour of backup.

The low backup time is because I used cheap lithium iron batteries, and there are only 3 of them.

NOTE:- I M NOT A TECH GUY. BUT I HAVE INTEREST IN TECH. I MAY BE MADE SOME MISTAKES.
