Of course there are generators, but they are quite expensive
if your power outages are rare.
I use a 12V deep discharge battery and a wall-wart trinkle
charger. I have a little 12V oscillating fan and a small 12V
flouresent light unit. So far this has worked well for me,
even in the 90 degree + temperature inside yesterday. When you
are old as I am the very heavy battery is hard to move around
so plan its home and your usual power outage retreat to be
close.
Perhaps if you have no power backup you might consider
something like this. The battery is by far the most expemsive
item.
The first time I drove my truck up near the house, ran 2 inverters off
of the battery and every once in a while I started the truck to
recharge the battery.
After that I made this to top up a battery.

I recall seeing a 120/240 vac alternator that could be installed under the hood of a pickup truck or SUV that was driven off the vehicle's engine and it was meant to be an emergency generator for your home. I saw it in Popular Science or Popular Mechanics many years ago and the thing was quite large which is why it was meant to go under the hood of a large vehicle with a lot of room under the hood. I searched a bit and found generators for service trucks but nothing like I remember seeing in the magazine. ?(?)?
They used to sell a regulator you could put on a car alternator that
put out 120v AC but at a very high frequency. It would run "universal"
motors (typically ones with brushes) or regular lights. I suppose it
also would work with wide mouth switching power supplies like new
electronics use.
I looked for a regulator or just a hack to make my little alternator
backup machine put out 40v or so that would charge my golf cart. That
is a big pack of deep cycle batteries that could be used in an
emergency.
So far, no joy on that. I can still use my machine to charge the
batteries 2 at a time.
Since then I did get a regular 5500w generator that I have never used
in 6 years. It is still in the box.
Power blinks are the most irritating thing to me. At home I only know the power went out because the ceiling fans quit and the UPS alarms go off. I had my buddy Stinky bring me one of my APC 500 Backup units to me here at the center for my computer stuff so I don't have to go through restarting everything if the power blinks. The center has at least one big Kohler genset. I have only see one transfer switch in a connecting hallway on one side of the complex and I believe I caught a glimpse of what could have been a big genset when medical transport took me out one of the back entrances to a back parking lot. I haven't had a chance to ask one of the maintenance guys about any backup generator the center has. If it's just one, I imagine it's quite large.ヽ(ヅ)ノ

I just put a new APC on my desktop. Old one had dead battery and
momentary power failure that crashes computer can be a real problem.
APCs are fairly cheap and easier to just get a new one than new battery.
I've never bought a UPS, all of mine are dumpster rescues including my 1kw and 750va units. I have a number of APC backups ranging from 350va to 650va and all I bought were batteries. I got the most common replacement, a 7ah 12volt, from a local electronic supply house for $16.00 ea. The batteries are very easy to change. I think I made out OK. ヽ(ヅ)ノ
