Tripp Lite's AVR750U line-interactive UPS offers complete protection for PCs, workstations and other sensitive electronics in an ultra-compact, mountable housing. Prevents data loss and system downtime by providing battery-supported AC output during blackouts and Automatic Voltage Regulation (AVR) during brownouts and overvoltages. Includes 12 output receptacles, 4 of which are widely spaced to accommodate large transformer blocks without obscuring adjacent outlets. 6 outlets feature full battery support and surge suppression, protecting computers, monitors and other vital system components from power loss. 6 additional outlets with surge suppression only are ideal for printers and other peripherals not requiring battery support. Single-line telephone suppression jacks protect modems, fax machines, cordless phones or other equipment with a DSL or standard dialup RJ-11 phone line connection. USB port with included cable and PowerAlert monitoring software enables safe unattended system shutdown in case of extended power failure. HID-compliant USB interface enables full integration with built-in power management and auto-shutdown features of Windows, Mac OS X and Linux. Audible alarm and front panel LEDs offer status information regarding line and battery power operation. 750VA / 450 watt power-handling ability supports entry-level PCs for up to 35 minutes during power

Random Shutdowns, a handy feature in a UPS
»
I bought this product from another vendor 5 months ago. It will now shut down at random times throughout the day. No warning, no errors.. just shut off. The battery tests all pass and I work at the power company so Im sure we have solid utility service :) I will never purchase another Tripp Lite product, we are an APC shop for life now.

Computer-& peripherals backup battery works great
»
I have owned the Tripp Lite 750VA backup battery for nearly a year. It backs up my desktop computer, monitor, router, modem, usb hub and one external hard drive. During two recent power outages, it worked without a glitch, and let me power down all of the above items in 7 or 8 minutes without a problem.

Terrible, buy an Ultra 2000VA UPS
»
This item is terrible. The problem is that it constantly monitors the quality of the incoming 120V line. If that 120V outlet in anything less than absolutely perfect this awful gadget starts beeping endlessly and stops working. So every time my neighbor opens his garage door and the voltage of my 120V outlet drops a fraction for a second this piece of junk starts beeping endlessly as if it were the end of the world. I wanted a simple battery to power my PC for a few minutes when the power fails, not a complicated idea. This thing instead monitors my homes 120V system and beeps loudly and constantly any time there is the slightest variation. I did not buy a gadget to monitor my homes electrical system, I wanted a battery to power my PC in case of power failures. Totally useless. Does not do what it is supposed to do. $30 in shipping to return due to weight. I didnt even try the software.

A used car battery and a sears battery charger would work infinitely better. Worst product I have bought in years.

Tripp-Lite TRIPS-A-LOT
»
Worked okay for about 3 months, and then started shutting itself down, with no warning, no beeping, nothing. Just shuts down. Starts right back up when you press the ON button, but will shut down again in a day, or in a week, or in two weeks, no rhyme or reason, just whenever it feels like it. Need an UPS for this UPS!!
