I don't understand. Why would it cost anything to run it? It's just a big battery. Maybe a small charge to keep it topped off?

It was a genuine question, I have ever used or needed one, therefore I have little to no idea how they operate.

It's just a big battery that you can plug things into full time. When power goes out it instantly switches to battery power. It recharges when the power comes back.
