    We get a lot of power outages during the winter, and of course, they're always unexpected. I use this one to power my internet box, because as long as than has power, the internet should work since most companies have their outlets on generators.

    Power surge compression and time to save work

    I’m very happy with the product. Out of the box. It took about a full minute to charge the battery and have the unit supply power but after that it worked. I wanted surge suppression and battery backup for a desktop computer. This will give me time to close apps and save work if the power goes out.

    I bought this to power a Mac Mini that kept getting shut off in the event of a power outage. Where I live, they don’t last longer than 30 minutes or so. This solves that problem. Although, if I was smart I would have bought one of these a long time ago. I hope my Mini can survive my laziness.

    Great basic UPS for low energy computers. Has successfully kept my computer running despite a power outage on more than one occasion. The amount of power it stores was more than enough time to safely power off the system.

    Time to replace my old APC unit - this one was on sale - as in the past, APC proves reliable and easy to configure. Even has "quiet" alarm setting if placed in a sensitive room. Love the new beep configurations. Highly recommended - check out similar models if you need higher wattage backup.

    I've had this for almost a year now and so far I haven't had any issues with it. It's saved my desktop computer from turning off serveral times now when the power has chipped out for a few seconds or minutes. I may buy a bigger one with a higher voltage for my computer and switch this one to my tv and wi-fi modem.

    Great Battery Back-Up UPS

    This battery back-up is an extremely nice economical solution. I only have 1 PC which I needed to protect and my utility company is very stable. My electricity, however, sometimes will flicker causing my PC to shutdown. This is a basic device and just the right size. I also like the design.

    Since I live in a rural area subject to power outages and surges, when my battery back up system died after 8 years I needed one quickly. The APC brand has always been reliable. This model is reasonably priced and not too large with lots of outlets. I've had it a while now and it has performed faultlessly.

    We have frequent brief power outages in Central Florida. Already had a heavy duty APC backup for my entertainment set up and got this small one for my PC and wireless router. Easy set up and already been in use a couple times. Worked well.

    Love this thing. I bought it to use for my wifi router hub & modem at work. It's been flawless through a couple power outages and takes up very little space mounted to the wall in my electrical closet.

    if you don't have one of these set up your modem and router to keep the internet alive when the power goes out, then you're missing out! easy to install once you push the very strong clip in the bottom.

    Easy to use & Good Product

    This backup is very simple, easy to use. APC is a brand I go to for battery backups (based on history of using in IT departments I once oversaw). I've never been disappointed. Power does fluctuate for us and this product (and the similar APC BU's I've purchased) work just the way you want.

    I already had one of these batteries at work so purchasing this one was an easy buy. Works great and has already saved me a few times from losing my information. 4 battery/surge protection outlets and 2 surge protection outlets gives you plenty of room for your electronics. Definitely worth the money.

    I have a freeze alarm system that I can access by phone and it can call me also with warnings. It has a 9 Volt backup battery which does not last long when power goes down. I installed this backup system and no longer have to deal with the short 9 volt battery life. Works great.

    Bought it for $29, mainly to avoid modem and router reboots because short power outages. It was easy to setup, turned of all sound notifications and forgot about it. It doesn't have much features, but form me main one is enough keeps my equipment powered and protected.

    After a surge blew some hdmi ports on my tv. I decided to by a battery backup. Now my electronics feels safe and im at peace. Nice black color hides very well. Plus my things stay on when the lights go out. Follow quick start instructions and you're good to go.

    Bought this item to protect valuable electronics in event of power failure or surge. Previously owned APC UPS that did the job for 10 years before it died. Hoping this one will last as long. Note that need to match the rating of the UPS to the power draw of the items connected to it.
