If you're talking about a UPS (Uninterruptible Power Supply) like people use for computers, you'll never be able to run a heater off one - they will run airstones, of course.
I'm a computer systems manager, so UPS's are something I'm familiar with. A decent sized tank requires a 250-300W heater. That's a similar power requirement as a full size computer "server" . If you spend, say, a $1000 on a UPS, you'll get one that will run a system of 300W for 1 hour of runtime.
For that same $1000, you can buy a 5000-7000W portable gas generator that will run your aquarium nearly indefinitely -- as well as some lights, TV and your refrigerator -- maybe even your furnace and other bigger systems if you have it wired into your electrical system.
