Tripp Lite AVR750U

Worked well for about two years. Provides battery+surge protection and surge protection only so you can pick and choose what you want to be on the UPS side

My unit was in service for about two years. Then it started to do the same thing as describe in other reviews. It would randomly shutoff, with no apparent pattern for why it would. Fortunately for me, I was using a laptop most of the time so it...

I have been a big Tripp Lite fan in the past. I decided to buy this to replace an old APC which lasted 3+ dependable years on the original battery. In the last 19 months, I have walked in to my computer room to see my computer completely shut off...
