Tripp Lite SmartOnline 120V 1.5kVA 1.35kW Double-Conversion Tower UPS

All of my computer equipment is connected to this UPS. It easily handles the 400 watts of power draw and will provide quite a bit of time to continue working and then shut down should a outage occur.

Had an issue with my ups, got though on the phone quickly, friendly support staff walked me through some trouble shooting and had a replacement to me in a couple of days

I have had my SU1500XLCD for much longer than it was registered (Don't ask me how I forgot to register THIS of all products)...I would say approx 4 years give or take and it still functions well. Maybe a 6 months back I had to replace the battery(s) finally which is expensive, and the replacement seems cheap, it may be going back to Tripp-Lite since it came with a cracked cable (Third Party Seller, but the cables are different than the original) and that would be my only complaint. It has served me faithfully without a single error all this time, still does and I ran it in double conversion mode (full protection) at all times, almost constantly for all that time. I can get 2 hours on battery (If I really want to drain it, which you shouldn't) using my custom rig, monitor, and speaker setup listening to music, programming, or watching movies. Playing resource intensive games cuts that in about half, depending on the game...sometimes more. This has seen voltage ranges between 124 and 110 without complaint or damage to my system in any way from the box, i never let it run if i noticed such a low voltage personally. All in all, it's still good enough after all these years to buy again if it weren't so expensive for me, the only thing that would have made this better is Lightning Strike protection to preserve your battery life, but you can only ask for so much I suppose. I can certainly recommend this product if you can afford it, and can't afford your equipment getting damaged or your computer shutting down without time to save your work. I can't speak for the replacement batteries, but I still got almost 4 years off the original set running it without eco mode or anything to extend its life. I can be run in multiple different countries through the settings and shut down remotely with the application that comes with it which can be as simple as USB for local shutdown. All in all, I love this thing...and i'm sure it saved at least my Power Supply multiple times
