A generator is like cheating

.
To experience a real power outage is to not have a generator lol like us. We were thinking about getting one, but firstly purchasing one is expensive and then the running costs are so high with the current petrol price.
I think they say it is 22 litres or something per 6 - 8 hours depending on the load which is R220 approximately per day or more. So we saved R1540+- towards other things

.
Is Petrol cheaper in the US or is it quite pricy?
Nice we had one, but we sold it years ago thinking we wouldn't need it again. Atm we got 6kg and 9kg gas bottles attached to small stove and skottle braai.
