UPS System, 550VA Power Rating, 115/120VAC Output Voltage, Number of Outlets: 8 is rated 4.9 out of 5 by 32.
Rated 4 out of 5 by from Worked the first day it was installed! Shortly after I installed the Tripp unit--on the same day it was delivered, our power went out and the unit did its job. We feel more protected having this connected to our computers. Also like that it is small and compact.

Rated 5 out of 5 by from Excellent Choice! I purchased my first device, and work ok but then had a problem. Looking for warranty I found a nearby store that took it in with few questions asked and replaced my unit in 1 week. The new device is working even better, and I can say this is a quality purchase if you are looking to protect core devices (without going the energy usage). Great product, great choice, totally recommended!

Rated 5 out of 5 by from I would buy this product again If you want to improve it, just cover the outlets and ventilation from the top.

Rated 5 out of 5 by from All I need Owned the ups for about 6 months and have had a few power flucuations with one outage. I have the internet modem, router, internet phone and main wireless phone base plugged into the battery. Surge protection has TV, Tivo and a few other components. When the outage occurred, all the battery connected components remained live, without interruption for over an hour. I feel much better knowing that all the expensive electronics will survive the power outages and flucuations. The only feature I wish the unit had would be a way to disable the beeping when the power is out. Overall, I am very pleased with the purchase!
