Rated 5 out of 5 by from Excellent power backupI have bought several of these. They are the only power backups I have found that work with our stand-by generator. We have fibre internet and our computers, TV and landline depend on it being up. We have tried other brands of backups and they will not work while the generator is supplying power. These, however, are dependable and reasonably priced. I will continue to buy them when I need a backup power supply.

Rated 5 out of 5 by from Good smaller size battery for brief outages.Works well and very happy with it. Use it to mitigate short term power outages. It keeps the computer powered long enough for an orderly save and shutdown by the user.

Rated 5 out of 5 by from I would buy againI use this to keep our computer, phone, & security system plugged in at work. It does exactly what it's supposed to do. If we lose power to that outlet, the Standby UPS holds power for at least 10 - 15 minutes so I can shut things down properly.

Rated 5 out of 5 by from nullWe recently had a power spike and the devices connected to this UPS were completely unaffected but those on a different (non-Tripp Lite) UPS lost power and the unsaved work on those devices.

Rated 5 out of 5 by from Great productWe've used pallets of these UPS and they've been really solid. Easier to deploy than comparable APC units as the battery is already hooked up.
