Our power will go out but normally for 30 minutes or less. I do not own the house so I am not going to buy a large back up system. I did bring a surge protector with battery back up and have my wifi plugged into that. So far if the power goes out I have had wifi the whole time and the unit only cost $50.
For the television and cable box I think I would need a larger unit but I can buy one. How hard would it be to have a system for one AC unit or maybe just a ceiling fan. Those KDK fans are great (we have 4 or them) and I see them everywhere. It would be a pretty cool design for KDK to have a ceiling fan with a built in battery back up for 30 minutes or more. I don't think a fan pulls a lot of power so I think the battery back up could be pretty small. I would think they would sell well in countries with power outages.
