Make your internet load shedding proof for R400.00

So I was tired of having no fibre during load shedding, and wasn't willing to pay multiple thousands for an inverter just to run the fibre router and the WiFi router. Fortunately I came up with a much more cost effective solution. If you already have a 10000mah power bank it'll cost you under R200, but even if you don't it'll cost you just about R400.

I have another two 10000mah power banks at home, and they both also work. The only reason I bought the big one was to test it for my office.
