    Perfect for those little power blips to maintain internet/router/wifi connection. Great compact size of unit. Plug is bulky and at awkward angle. Big plus to have USB ports.

    Excellent product. Been using a battery backup for many years and would not be without it. Best Buy has never let me down. I recommend Best Buy to all my many friends throughout this wonderful United States of America in which I have lived for over 92 years

    I like the idea of having a protective power strip cord with a built in battery so if the power goes out by storm or tripped breaker, i have time to shut devices down correctly without losing progress!

    Power went out the other day for over 3 hours. Kept my Modem, router, and small poe switch powering aps running from 11:30 to 3. The estimate on the device is is "308 minutes" and it at least made 240 that day. Super happy with my purchase and will be purchasing more!

    I've over the course of several years bought these units, APC and Tripplite for my home. I've found that these unit's batteries have a better longevity versus the other 2. On average these batteries will last 2-4 years with a small number lasting more than that. I also like that they've included in these 2 units (2) 2.4A USB charging ports thus freeing up 2 more of the outlets! That is a great bonus and much appreciated.

    CyberPower UPS was purchased because my 2nd APC UPS crapped out after 4 years. I expected at least 10 years of service from my UPS. My 1st APC lasted 10 years.

    I use this supply to back up my security system power. It works as advertised, but even though it has eight outlets, only four of them are battery protected. The other four are just surge protected. The main problem is that the four outlets that are battery protected are all so close together that the equipment that I have (router, cable modem, etc), cannot all plugin together because those items have small power blocks that cover at least one extra outlet. The power supply should be redesigned to use some of the blank space to space out the outlets so that it will accommodate power bricks.

    This was bought as a backup for my cable modem and router.Tested it by unplugging it from the wall and it kept both devices going for 15 mins upon which I plugged it back in. Had a power outage and it kept devices going for at least a half hour (longest I have had a power outage for.) Great price for the backup and safety it provides for smaller devices!
