The unit arrived at my location in good condition. Four stars because it hasn't been tested under a real situation. Hopefully never. Would recommend that USB ports be put on The unit to charge cell phone devices and other such items from the battery. we are not utilizing the power alert software on this unit for various reasons. We have 3 other units that are working successfully with the power alert feature. so far so good.!
I use the UPS for a small tv, router, internet TV box and a wireless phone base. After you connect everything, the device shows you your wattage and how many minutes it would take to run it down. Also, sound alarm can be turned off without connecting the unit to a computer. I have an older TrippLite model which looks exact same and is about six years old now. It still works and outlasts powe outages here.
I use this only occasionally as a UPS for tabletop repair of other computers. Not used regularly. I bring it out of the closet in order to power up repair projects. I have had good luck with other Tripplite products so am confidant that this will work well.
I am able to plug in all my equipment and it works great. I haven't had any failures at all since I got this backup. I love it! I used to use another brand for my backup needs but now I am sold on Tripp-Lite and will always buy.
I purchased two of these, replacing two aging APCs. I like the information available through the display, since one of these is not connected to a computer. We've had one power outage since I bought the units and both worked flawlessly. My only complaint is minor. I run Linux Mint on my computer but could not find monitoring software for the UPS. No big deal since the on-device display provides all the information needed.
