I want to do the power back-up thing too, but would prefer the automatic UPS as me not being there at the time may be an issue. Having said that....so if one were to run just one 20W MaxiJet 1200 powerhead off a UPS, am I correct to assume that that powerhead would run for .... 200W / 20W = 10. 10 x 22 minutes = 220 minutes, or 3 Hours and 40 minutes?

Thanx much,
