I had a power outage 2 months later and this device worked very well. you'll get a loud beeping sound from it when the back-up battery system is working So far, so good. This device gets the job done.
I would recommend this to a friendBUYER BEWARE
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this for battery backup in case of power outage. Only have wifi router, cordless phone, and lamp plugged in to it. First power outage - no juice whatsoever, and constant beeping indicating that battery was low - even though it has been plugged into a live outlet since date of purchase. CyberPower Company was non-responsive to my inquiry while not even 1/2 way through warranty period. I do NOT recommend this item.

Posted .Most UPS batteries have an expected life of 3-5 years, but other factors can also shorten the life of the battery, such as temperature, humidity, and frequency of power event. Thank you for your review!
Used this on a light load, for two weeks.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Used this to keep power to my cable modem box, and router signal booster. It went out in about two weeks. The unit powered off, and there had been no power failure. An alarm was sounding and it wouldn't reset or restart, and the alarm kept going. Tried everything. Unplugged and returned to the store. I noticed that the insides were rattling around when I boxed it up. It had not been dropped. Junk UPS. Do not buy this. $50 wasted, but Best Buy refunded it. It was pas the 30 day refund date but I had been on vacation for two weeks during this time.

||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Power to the surge protector side. No power to battery backup side.

Did not last a year
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have lost power a couple times since I've had this back up and each time it worked like a charm. I lost power briefly today and the battery backup did not kick on. It continued to screech with a high pitched tone till I reset it. I have only had for 10 months and this is unacceptable. Will not use this brand again. I had much better luck with the competitor brand.

Battery Backup Surge Protector
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Item does not work for what I bought it for. Our electric went out and the modem on my computer shut down. I work from home and need the system to stay up. At least long enough for me to save work and close out correctly.

Failed after 18 months and ruined my data
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Failed after 18 months: Instead of protecting my system, it failed and corrupted the database of my home automation system by abruptly cutting off power, signaled by a continuous beep alert during the failure.

Posted .Hello Evan, the constant tone coming from the UPS indicates the UPS was overloaded and shut down power to the connected equipment. This happens when to much wattage is being drawn from the UPS. We recommend moving a device to the surge only side to not continue to overload the UPS. Please contact our technical support if you have any questions or concerns regarding the product at 1.877.297.6937 and dial 1 for technical support.
