Computer UPS units may be good for VERY short outages of less then, say, 30 minutes. Maybe less, depending on how high humidification is set. But not much more than that. Try to avoid them. They were built to allow you to shut down your computer gracefully if power goes out, not keep on running the machines. They are horribly inefficient due to several current conversion cycles (120 V AC hosue voltage down to 12 V DC battery voltage back up to 120V AC through an inverter to power the UPS output then back down to 12 V DC for the machine). Also, the internal batteries are relatively small to start with in most household units.
I just wake up if the power goes out. If not, no big whoop as you are not going to suffocate. I used to get up and rig battery for he rest of the night, now I have a home brew, dedicated UPS built specifically for this purpose that will get me comfortably through a night without bypassing humidification (JustMongo already described it - thanks, Mongo!). After the first night, humidification has to go as it eats up SO much power...
Actually, the OMMOHY approach does auto switch. You do have to DIY it.
