we bought a honda generator for back up. If I'm gone for the day I'll drop an airstone for a battery operated pump. Power goes off, at least there is an airstone. For my new build, I want to get one or 2 of the ice caps??? battery backups for 1 or 2 power heads. All that would work until generator is going. Generator will take care of my tanks, at least most of what is crucial as I'll have 2 tanks soon, my mom's tv and the fridges and freezer. And charge electronics. Not sure if it will also do my hubby's computer. I have a laptop so I have some power and can recharge.
We learned that if you want a generator get it BEFORE there are any disasters. With all the fires in CA, the cheap generator we were considering went out of stock, and then doubled in price! All of them did this. So we decided if we had to pay 1000 bucks, we'd buy the honda as it has a proven track record and you can get parts.
