For over a decade, an old APC 1500VA UPS has kept my home theater system up and running during brownouts and blackouts. The battery finally decided it had lived long enough and gave up the ghost. As I've gotten older I've come to the realization that I tend to go a little overboard on these things and am turning to the hive mind here to give me some more reasonable ideas as I move forward. I am even willing to consider that a UPS has been a pointless waste of money if that's what the experts say. Here's what sits in my home theater area, powered by the APC and a Tripp-Lite unit hooked up to one of the powered ports: LCD TV Cable modem Edgerouter X PoE injector for an AC-Pro FireTV Ooma Phone NAS BluRay The cable modem and router aren't on my office UPS because the landlord didn't authorize running a working line into the bedroom we use as an office. I am trying to create space for the NAS to be moved in here (it's a very tight space).
