Well here's a suggestion - a little crazy - but works... Most equipment is taking the 120vac and converting it into DC voltage. So why not just feed it DC voltage directly??? We had a situation where our field techs needed to test dsl circuits and voip ata from the demarcation point outside a house or business. A UPS might have worked - but the down conversion of 12v dc battery in ups up to 120vac to power the plugs on the ata and modem - just to convert back down to 12 and 5.. Make sense... Common electronics theory tells you that there is waste in step-up/step-down === heat... So maybe that's an idea... I took a UPS battery and a small project case from common electronics retail store... Then bought me a very small voltage regulator and soldered it in the case.... I was able to split off 12v and 5v from the ups battery and run for days... Sounds like weird science - but it works!!
