I would buy this product again.
I have a few of these. Up until the last unit, the batteries could not be replaced. When the batteries died, the unit had to be replaced. The newer units have the ability to replace the batteries.

Does the job, simple setup
Would be good to have some spacing for one outlet to account for a power brick as opposed to a simple plug. Simple to setup and get working with the web app. I like that the battery is accessible for replacement. Initial testing of backup power successful, no real-world test has happened as yet.

Mi trabajo siempre debe estar protegido con TrippLite
Mi tripplite lo uso para proteger mis trabajos, lo que me permite en un solo esfuerzo cumplir con mi trabajo. No tener esta protección me ha causado muchos dolores de cabeza.

This will be a life savor for us.
I use this for power backup for my network equipment. If modem and/or router go down, it takes a while and a complicated process to get everything back on line. If we are away, we lose visibility to our security cameras and ability to control lighting.

Great product for typical desktop setups
This works great for typical desktop setups, just be sure not to overload the unit, otherwise you're not going to be happy with the battery shutting off after 30 seconds.

Both require AC power. We live in a 100 acre forest and our dedicated power line is 1/3rd mile, so the power goes out more frequently than urban locations. The power went out yesterday for a couple of hours and the UPS worked great... we used the phones during the outage.

Rated 5 out of 5 by from Buy a lot of these Tripp Lite for my users I had been buying these particular models for a while know. Fairly reliable battery backups. Love compact or smaller design battery backups that are not very bulky and take a lot of space.

Rated 5 out of 5 by from Beeps occassionally It is a simple to use/hook up device. Works pretty well but gets over powered fairly easily. It beeps if it has too much power being pulled from it. Last me three years so far and still going.

Rated 5 out of 5 by from null Great small form UPS for the end users. Really basic UPS but its cheap and cost effective to have one of these babies under every employees desk and plugged into printers! Nice spacing between each outlet that fits a lot of the bigger AC adapters.

Rated 5 out of 5 by from null We use Tripp Lite UPS units as an economical alternative to APC products. They are extremely reliable and battery replacement is very easy. I've never had one fail when the power went out.

Rated 5 out of 5 by from null I have two of these units at two different offices for the same job but different experiences. The first office works well. No drops, no outages. The second office it has to be unplugged and plugged back in about once a week to get it to keep providing power during a local power fluctuation. One number off on serial numbers between the two units. I'm currently working on addressing these issues with TrippLite.

Rated 5 out of 5 by from null Have these installed on every PC in our environment. Works great. However, i'd stagger your deployment or you'll be replacing batteries in all of them at once. Batteries seem to last about 2 years before needing a replacement. Only problem I've had is not getting a warning when batteries need replacement. Didn't realize some were dead until the power went out and the PCs lost power. I thought there was an early warning, but it didn't seem to work correctly.

Rated 5 out of 5 by from null This is a great, standard, desktop unit that easily competes with another well known brand. But, I really like the widely spaced outlets to support those bulky adapters.

Rated 5 out of 5 by from null Use these around the office for all of our workstations. Never had any issues. We've had outages due to thunder storms, floods and hurricanes over in New England. The UPS has done its job and been able to allow users those extra precious minutes in order to save their work and shutdown.

Rated 5 out of 5 by from null Recently purchased another of these units to protect our CAD systems. We have engineers in rather remote locations where power can be unstable during winter and spring. This unit is great for providing that extra protection and to keep the Engineers from losing valuable data.

Rated 5 out of 5 by from null This unit fit perfectly for mounting on a backboard and supplying clean power to our new 50mbps Ethernet Switch. The 17 minute battery will be adequate for our too frequent brown outs.

Rated 5 out of 5 by from null We ordered a few of these to see how they matched up with APC and the results were horrible for this product. They did not last even a year. Needless to say we went back with APC.

Rated 5 out of 5 by from null I have used this for a couple of months now. Longer cord that helps position it where we need to. Does not seem as bulky as other UPS. This will come in hand during storm season. Which is in full swing.
