This is the fourth identical unit that I have purchased in the last 18 months for our customer installations supporting high performance PC's. Our environment suffers from severe storms and multiple blackouts during the winter season.

By experience I have found that the Tripplite AVR circuits regulate fluctuations easily and that the UPS function switches on nearly instantly with enough stamina to keep our computers running and when necessary the automatic shutdown circuit interface with Microsoft Windows works perfectly.

The other reviewers here are all companies, but there's one fatal flaw for this unit for home use. It works fine for its main function, but there's one thing it does that it shouldn't... Beep... Forever... Unceasingly. There's no way to turn it off. I even tried to use the digital interface to modify the settings, but couldn't get it to go away.
So if you have it any where near your bedroom, or really anywhere within earshot, it will wake you up or drive you crazy.
With a mute button, this would be a great unit, without it, it's maddening.

Comments about Tripp Lite UPS 550VA 300W Desktop Battery Back Up Compact 120V USB RJ11 PC:

A brief loss of power and surge in an instant power return killed the battery in our AVR550U. Of course, that meant that none of the equipment plugged into it was damaged. Tripplite was 100% terrific in providing a new unit. It was easy to install and has our Audio/Visual equipment is protected again. Thank you Tripplite!

            Aside from a lack of directions (you have to hold down the on/off button until it beeps), this is a perfectly functional UPS for any low power or short term needs. It has more than enough outlets and can even take my laser printer without complaining.

            Needed a GPS for our pellet stove in case of power outages and was very impressed with the capabilities of the unit when it arrived. It is more than capable of providing safe shutdown when ever there is a power outage. Plus with five protected plugins and five non protected five non protected plugins. There's enough plugins for the whole living room. I love it! Piece of mind 24/7

            Shortly after I installed the Tripp unit--on the same day it was delivered, our power went out and the unit did its job. We feel more protected having this connected to our computers. Also like that it is small and compact.

            Comments about Tripp Lite UPS 550VA 300W Desktop Battery Back Up Compact 120V USB RJ11 PC:

            This product works pretty well. Since plugging it up we have had two power outages and it's been about a month. The first time everything went out except the TV and Playstation which were connected to the Internet Office Battery Back up. We just turned those off ourselves just in case. The second time we didn't even know that the power had went off until the Battery Back up went off. We were in the middle of a game and were able to shut down the Playstation safely

            I purchased my first device, and work ok but then had a problem. Looking for warranty I found a nearby store that took it in with few questions asked and replaced my unit in 1 week. The new device is working even better, and I can say this is a quality purchase if you are looking to protect core devices (without going the energy usage). Great product, great choice, totally recommended!
