This is the fourth identical unit that I have purchased in the last 18 months for our customer installations supporting high performance PC's. Our environment suffers from severe storms and multiple blackouts during the winter season.

By experience I have found that the Tripplite AVR circuits regulate fluctuations easily and that the UPS function switches on nearly instantly with enough stamina to keep our computers running and when necessary the automatic shutdown circuit interface with Microsoft Windows works perfectly.

The other reviewers here are all companies, but there's one fatal flaw for this unit for home use. It works fine for its main function, but there's one thing it does that it shouldn't... Beep... Forever... Unceasingly. There's no way to turn it off. I even tried to use the digital interface to modify the settings, but couldn't get it to go away.
So if you have it any where near your bedroom, or really anywhere within earshot, it will wake you up or drive you crazy.
With a mute button, this would be a great unit, without it, it's maddening.

Worked the first day it was installed!

Comments about Tripp Lite AVR 550VA Mini-Desktop UPS:

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.

Pretty Good Battery Back Up

By bjw442

Comments about Tripp Lite AVR 550VA Mini-Desktop UPS:

This product works pretty well. Since plugging it up we have had two power outages and it's been about a month. The first time everything went out except the TV and Playstation which were connected to the Internet Office Battery Back up. We just turned those off ourselves just in case. The second time we didn't even know that the power had went off until the Battery Back up went off. We were in the middle of a game and were able to shut down the Playstation safely

At times we have power surges in the office & it's nice to know the equipment connected are protected. The feature that it will shut the computer down after the power is off is really nice.

Comments about Tripp Lite AVR 550VA Mini-Desktop UPS:

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!

Cartridge Comparison Guide
  • Cartridge Types
  • Ink & Toner Basics
  • Number of Pages & Shelf Life
Cartridge Type
Genuine or OEM (Original) Cartridges Remanufactured Cartridges Compatible Cartridges
Description OEM stands for original equipment manufacturer, meaning the cartridge was made by the same company that made your printer. Original brand cartridges are very reliable and sometimes the only option if your printer is new to market or uncommon. Remanufactured ink is a genuine brand cartridge that has gone through one cycle of use. After use, the cartridge is recycled, acquired by a remanufacturing facility and put through a rigorous professional refurbishing process. During the refurbishing process the cartridge is disassembled, thoroughly cleaned and tested for quality. It's then carefully refilled, tested again and brought back to life. Buying remanufactured prevents one less cartridge from ending up in a landfill. A compatible cartridge is a brand new ink cartridge built by a manufacturer other than your printer. It's like buying the generic version of the genuine brand. Most are uniquely designed to differentiate from genuine cartridges. Despite any structural difference you may notice, the cartridge will still fit in your machine and print a full yield, just like the original brand.
Price Factors Many printer manufacturers follow the razor-and-blades business model which may result in higher priced genuine cartridges. Remanufactured ink is much cheaper than the original brand ink. It's far more cost effective to refurbish a previously used cartridge than create a new OEM from scratch. Compatible ink is much cheaper than the original brand. Compatible suppliers don't have to worry about the additional costs that hinder OEMs like new printers or firmware, which lets them keep prices low.
Quality Original cartridges work extremely well and are covered under a warranty by the printer manufacturer High quality remanufactured ink will match the quality of the original, but not all remanufactured ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results. High quality compatible ink will match the quality of the original, but not all compatible ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results.
What's the difference between ink and toner cartridges?
Ink Cartridges Toner Cartridges
Printer Type Work with inkjet printers Work with laser printers
Material Liquid ink Dry powder
How it works Inkjet printers use a series of nozzles that spray tiny drops of ink directly on the print suface Laser toner printers use static electricity and heat to bond dry toner powder to a page
Commonly used by Casual home users, small business and photographers Large businesses and schools
Number of Pages You Can Print A cartridge's page yield is the estimated number of pages you can print. Page yield is based on 5% page coverage. This means that the quoted page yield is based upon printed pages where only 5% of the page has been imprinted with ink. For example, a short memo has approximately 5% coverage. If you have a cartridge that has a yield of 500 pages, it can print 500 pages of that short memo. If you are printing letters, photos or graphics, your coverage will vary greatly and your page yield will drop significantly.
Cartridge Warranty and Shelf Life Most ink and toner cartridges include a warranty or "best by" date on their box. Remanufactured and compatible ink cartridges can last 12-18 months unopened, and toner cartridges can last up to 3 years.
Cartridge Care and Storage Only open a cartridge when you need it. Opened cartridges will eventually dry out, especially if the protective tape or clip has been removed. If you have an open ink cartridge around and would like to try and prevent it from drying out, place it nozzle side up in a plastic airtight tub. If your cartridge came with protective tape or a clip reapply both before storing. Place a damp cloth or paper towel in the tub, next to the cartridge and keep it stored in a cool, dark place.
