I currently have UFB on order and am looking into getting a UPS to keep the ONT and Router running during a power outage (I am with Spark so the phone is connected to the ONT, not the router). I have been looking at the CyberPower BRICs 850VA floor model, the APC Back-UPS series and the Fuel Cube that Spark recommends. Does anyone have one of these and could comment on run-time (for a Chorus ONT and a Netgear N600 Modem/Router) or give advice for selecting a UPS. I am looking for ideally 4 hours of run-time. Thanks.
