Tripp Lite's AVR550U 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 over voltages. 8 output receptacles, 2 of which are widely spaced to accommodate large transformer plugs without blocking outlets. 4 outlets feature full battery support and surge suppression, protecting computers, monitors and other vital system components from loss of power. 4 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 and other equipment with standard dialup or DSL RJ-11 phone line connections. USB port with included cable and PowerAlert monitoring software enables safe unattended system shutdown in the case of extended power failure. HID-compliant USB interface enables integration with built-in power management and auto shutdown features of Windows and Mac OS X. Audible alarm and front panel LEDs offer status information regarding line and battery power operation. 550VA/300 watt power handling ability supports entry-level PCs for up to 17 minutes during power failures.

    Heavy but great and durable
    Your review:
    The only thing I have to say that is negative about this is that it is very heavy, but being a battery, I expect that. I like how it has a nice long cord, and the buzzer for when power is cut is loud enough that you can definitely hear it and act before losing power to your devices and computers. I really like this product, and would recommend it to anyone looking for a quality battery back up surge protector.

    Nice drop-in replacement for battery-killing UPS
    Your review:
    I bought this to replace an otherwise similar UPS from a different brand because I was sick of the other UPS wearing out my batteries. I'm looking forward to the battery lasting much longer now that I have a line-interactive UPS. Best thing about this UPS: the wall-mount holes on the back are _exactly the same distance apart_ as they were on the other UPS, so I didn't have to take out one of the old screws and put in a new one. that _can't_ be a coincidence, can it?

    An inexpensive security blanket for my computer
    Your review:
    I bought this to protect my computer during the short power outages that occur. Although I have not had to depend upon it to date, I have unplugged it from the wall without noting a problem with the computer.

    Your review:
    This was the perfect battery pack for our electronic room it was big enough to fit all the power cables and it was a very reasonable price. Will defiantly be purchasing more. The added bonus was the warranty !

    Adequate for need but shorter run time.
    Your review:
    Product arrived as expected, easy to register the warranty online. Charged fully for 2 days then did a capacity test. All worked fine except at a 240w draw, unit only lasted 5 minutes 10 seconds before shutting down. Included paperwork said 40+ minutes at 50% capacity. Battery may last longer after it's used a few times. Unit should work fine for my needs, just need to make sure the computer is shut down right away, no waiting to see if power is going to come back on. Have had good luck with TrippLite previously so that's why I purchased again.

    I would recommend this unit as a backup unit.
    Your review:
    The product is nice for the number of plus that it has both on backup and surge. The only complaint I have is that the mounting holes in the back are desinged for it to be monted vertily. The mounting slots should be mad that you can mount the unit both vertily or horizontal. The slots should be in an L or X design. I haven't had a reason to test the backup (no power failure yet). Just have computer monitor and modem/WyFi on it.

    Would I purchase another unit? Yes.
    Your review:
    Purchased this unit t protect my overly expensive flat panel. I have since added all my electronics to the UPS. NO issues working as expected. Would I purchase another unit? Yes.

    I would buy this product again and again.
    Your review:
    I purchased this UPS again to replace the same unit that finally failed after more than 10 years of service protecting phone equipment against power surges. This unit does a more than adequate job for a great price and a great warranty.
