UPS System, 550VA Power Rating, 115/120VAC Output Voltage, Number of Outlets: 8 is rated 4.7 out of 5 by 9.
Rated 2 out of 5 by from Can't Replace Battery Major problem in my eyes since when the battery dies the battery backup is no longer useful. I didn't realize you couldn't change the battery when I bought it. I would recommend buying one with a user service access panel for the battery

Rated 5 out of 5 by from Perfect for my Entertainment Center I use this for my 65" LCD and Dish Network DVR as a backup against sudden power outages. It's funny when the power goes out and I'm still watching TV! It gives me enough time to power down each device correctly instead of them taking a direct hit.

Rated 5 out of 5 by from Love this unit! I am an application developer and work from home 50-hours per week. We get temporary outages (10 seconds to 4 minutes) on a weekly basis and my two INTERNET550SER's keep my laptop, 4 monitors and Internet connection up and running. I love these units. I can plug them in and feel confident that my equipment will stay powered.

Rated 5 out of 5 by from Generator Switchover Working in a government office we have a large generator that kicks in if we loose power. Sometimes it takes a minute for it to switch over, just enough time for the computers to loose power. We installed the Tripp-Lite's at every workstation and now when we switch to generators our computers remain on. Also, we don't have to worry about power surges when power is restored.

Rated 5 out of 5 by from Ready to go, right out of the box. Installation was simple, instructions were clear, and the unit performed exactly as the literature explained. The camera system in our building failed due to an unexpected failure of a similar UPS unit, causing a loss of monitoring of the site, and also caused a video monitor to fail. The Tripp unit offered an interface with the controlling computer, allowing an unattended shutdown. Very satisfied with the unit.
