Rated 4.4 out of 5 by 23reviewers.
Rated 4 out of 5 LIght weight for how much protection I like the room between each outlet. Makes it easy to plug in larger adaptors. Hooked it up to the PC and it was easily detected in Windows 8.1. I wish that I didn't need a screwdriver for battery replacement. Great unit, great price. March 16, 2015
Rated 4 out of 5 Light weight and portable for the VAs I was surprised how light the unit was. I wished that you would not have to unscrew screws to replace the battery. That is my only issue. February 25, 2015
Rated 4 out of 5 by works great out of the box Simple device, simple set up, plugged it in and it works. January 28, 2015
Rated 4 out of 5 by good and bad Has been doing a good job. Dislike that you can't turn it on without it making the harsh warning sound. Power went out the other night and so did the computer system, so I guess the internal battery has failed which is pretty typical no matter what brand I've used. September 30, 2014
Rated 5 out of 5 by Solid, working UPS Having watched more than a couple power outages shut everything else down, it was great having a little more time to also shut down my PC and monitor. After several outages through which the Internet 550U protected my gear, I'm a believer and this is all the backup needed. September 30, 2014
Rated 1 out of 5 by Failed after less than a month I originally had a Belkin UPS that lasted for years, far beyond it's warranty. Then I went to my local Electronics store and all they had was TrippLite UPS. I bought it and it died a month after it's warranty expired. Went and got another, and it died in less than a month. Returned it and got a APC. Works just fine. We'll see how long it lasts. Can't honestly recommend TrippLite. September 30, 2014
Rated 5 out of 5 by Excellent product/ excellent customer service I have had wonderful success with the UPS 550VA. I had what I thought was a problem and called customer service. The error was with our purchasing department not verifying the amount of wattage we needed for the battery back up side. Customer service went over every item we had plugged into the battery backup side and within minutes found that there was too much voltage plugged in. I was able to immediately fix my problem. Thank you to your customer service for friendly, and prompt help. My Tripp-Lite works wonderfully. September 22, 2013
Rated 5 out of 5 by It's there when the power fails. What I want of a UPS is that it be quiet, unobtrusive and there when I need it. This UPS does that for our workstations. September 8, 2013
