A Nice Battery Backup Unit
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This unit has a higher capacity than most for the price. Plenty of plugs for devices. CyberPower has a very good software that can be downloaded free to check the operation of the unit and control the computer shutdown time in case of a power outage. It was very easy to install.

Nice to Have Power Backup
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this for my office set up and it works great! Feel at ease and comfortable knowing that I have backup power when needed. It does beep a bunch when disconnected from power which is annoying but also indicative of power loss.

Does well but not for multiple electronics
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Our neighborhood has all kinds of power surges and outages. It has killed two computers to date. Bought this in the hopes it would give us enough time to turn off the computers if the power goes out. It works great for one computer. However more than one it doesn’t work. It has a powerful sound that it makes though. Overall great product. Just wish it would have worked for all our computers without buying multiple.

Love it!!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Nice UPS. Using it for power backup for my router. Decent number of power ports. I was looking for something more flat and small and this one did the trick. I have put it in my small corner table. Takes very less space and looks neat.

Works like it should
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This works well as a battery back up for my computer. I have had the identical model before and it lasted for years. If the power goes off it gives me time to close everything out.

Works fine. Silent mode is a huge plus.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Works fine. Silent mode is a huge plus. The power LED is not the power button, so it was simple to tape over it without interfering with the normal operation. Therefore, I recommend for a bedroom if you're sensitive about lights. The two USB ports are nice, too.

UPS for my cable internet during power outages.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I set this up with my cable booster, cable modem and wireless router. I am hoping that this will allow me to maintain internet connection while power is out for a few hours. Hasn’t had to be tested yet but we will see. Fingers crossed.

Great Battery Back Up System
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With the storms that roll through Tampa and frequent power outages, this battery back up is just enough to keep my system running until I can either save and shut down properly, or get to my office to perform the shut down. I have this model on 30+ workstations - highly recommend!

Reliable battery back-up for your electronics!

Perfect Function in Lighting Storm & Loss of Power
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Yeah, It does what it is supposed to do. It guarded my computer, and supplied backup power for well over a half an hour. Also attached to it are my scanner, external hard drive, and monitor. This review comes after brief ownership.

Worth it!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Had to buy another one because my last one died (after 12 years, good run!). Great to use with my TiVo or router to keep them from having to totally power cycle when the power dips.
