Rated 5 out of 5 by Excellent support and timeliness Tripp Lite provided excellent support when the product I purchased stopped functioning. Their customer service provided some steps to help determine if the device worked and when they determined the unit was at fault Tripp Lite quickly sent a replacement. Great support and team at Tripp Lite. March 15, 2015
Rated 5 out of 5 Great product, great price We continue to buy this identical unit for various installations of our desktop hardware that we provide to our clients, The units AVR feature adds stability and long life to our equipment and we find the battery life to be exemplary. March 15, 2015
Rated 5 out of 5 by Safty for TV and PS3 and PS4 Got 2 of AVR550U to secure and protect our TV and connected game console PS3 and PS4. Works great and still does it job! Also just got TripLite SMART1500LCDT for computer/server. February 25, 2015
Rated 5 out of 5 by great product This product has allowed us to continue enjoying our electronic entertainment during many short lasting outages. February 25, 2015
Rated 5 out of 5 Tripplite Quality at a great price 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. January 13, 2015
Rated 5 out of 5 by Works great; good price. I have four Tripp-Lite UPS--one for each computer and one for the stereo gear and TV. I don't care a great deal about fancy features. What I want is solid protection and that's what I get with Tripp-Lite. Highly recommended. January 13, 2015
Rated 5 out of 5 by Good product for a reasonable price. Have purchased several AVR550U for individual work stations in a small office setting and they have worked well during the many power outages. They enable the user to save working documents and then shut down until power is restored. October 14, 2014
Rated 4 out of 5 by works well This is a good product. We often have outages, but this has kept computer up long enough to save data, and then some. September 30, 2014

I am having problems with inconsistent power, will this unit if plugged into the battery section, provide consistent power even if the power from the wall fluctuates? I am not worried about power outages I need to keep the voltage drops from effecting my computer.

The 1AYA4 is a line interactive unit and therefore has voltage regulation. The manufacturer states: "Built-in Automatic Voltage Regulation (AVR) boosts brownouts as low as 83 and reduces overvoltages up to 147 back to usable 120V nominal levels." PC's are one of the suggested types of equipment that may benefit from the use of this product.
