    • Terrible customer service, won't stand behind product.

I rarely write Amazon reviews, but in this case I was totally disgusted by the lack of customer service for existing customers. Although cyberpower UPS units are cheaper in general than APC, I've found that cyberpower will not stand behind their products. When the battery went dead on this unit I removed it and tried to find a replacement, only to find they are priced around 2/3 or more of buying a whole new unit. When I emailed cyberpower about this I got a reply from tech support saying this wasn't a "user-serviceable" battery. I then asked if they had a pro-rated replacement for existing customers. The reply I got was very dismissive and basically ended with the equivalent of "tough luck". Following is the last reply from them: "The unit has a torx security screw holding the compartment in place. Some users have discovered what size torx head this uses and have been able to upgrade their own batteries, but unfortunately, I am unable to assist with that. Unfortunately, we do not have any sort of upgrade program. Thanks, and have a great day!" Yeah, thanks a lot. I tried this UPS because it was cheaper, but I don't feel it's worth it if you have to buy a new one when the battery dies. I'll go back to buying APC units, since I've never had a problem getting a reasonably priced replacement battery. Buy at your own risk. ... show more

    • Expectations are critical here
Size: 425VA Style: UPS
It seems like when I read lot of existing reviews for this item there is plenty of disappointment. When I read what they're trying to power with these things it looks to me like expectations are way too high. These are very very small units. Even the largest one grouped on this page I would not consider to be adequate for a desktop computer. None-the-less, I confess I am confused to see this series of UPS promoted for (among other things) desktop computers and home theaters...big items with big power draws even though the largest in this series is only capable of providing a maximum of 400 watts and then only for 2 minutes (no doubt only achievable with a battery in perfect condition)! Considering I'm being asked as part of the review to rate WiFi signal be a big clue that somebody is terribly confused about what a UPS actually is and why you might want one of these in particular. All that said, think small devices. Think chargers, security system, an emergency LED light or two, maybe an average laptop (if it's own built in battery is lacking). I bought this specifically as a backup for our FiOS ONT (optical network terminator) so that internet would continue during a power outage. That is all this one does. I have a second slightly larger unit running all my networking equipment so WiFi and network jacks stay up and the internet remains serviceable during a power outage for a reasonable length of time (not indefinitely, not for a day, even an hour might even be pushing it), but certainly long enough to coast through a typical short term outage. And I haven't even had it a month and already it was tested earlier this week when the power went out for about 30 minutes, came back for about 10 minutes, then went off again for another 20. Internet stayed up and the kids probably never even noticed, and I was able to continue work from home on a laptop. The UPSes, all of them, operated well within ratings, performed as advertised: flawlessly. ... show more

    • Keeps me connected
Size: 350VA Style: UPS
Long power outages (5 to 13 hours) happen where I live as often as twice a month, and since we're in a dead zone for cell coverage we have to use wireless at home, so without power I don't even have a phone connection. This UPS is just right for keeping my cable modem, wired/wireless network and VOIP phone working during a long power outage. It's the kind of thing where there's not a lot to say about it. Either it works when you need it, or not. This works. ... show more

    • Compact fit and enough power delivery.
Size: 350VA Style: UPS
My boss bought one of these for work to keep a PC and one monitor powered during power blips. When it came in, I couldn't believe how small it was. I've been looking for a very small UPS to use just for my modem and router as I get a lot of power blips in my house at random time of the day. Everything else is protected but the networking equipment. This means that while my PC or PS4 will not shut off, I still had to wait for my router and modem to both restart and work again. The placement of my modem and router was also the issue. It is in the living room sitting on a decorative half-table. I have also purchased a power strip cover/box that you put your power strip inside so it doesn't look like a jumble mess of cables. This UPS fits in it! Now I am able to keep my devices powered for a bit when there's a power outage. I even had a blip recently and it held through. You just hear the clicking sound of it switching to battery and back to normal. I recommend this if all you need to power is a TV and one device. ... show more

    • Annoying and Helpful
Size: 350VA Style: UPS
I agree with the annoying beeping noise everyone is commenting about. But honestly if it wasn’t for that I wouldn’t even notice that the power went out. So I love this. I have my tv and my modem/router connected to this and I could actually stay watching tv for at least 5-10 minutes before it starts going crazy and if I just turn off the tv it’ll beep periodically until it beeps like crazy again if the power hasn’t came back on probably another 10-15minutes more or less. At first I also had my Xbox connected to this by the battery and oOf that was a bad idea 😅 it’ll immediately start beeping like crazy if that’s connected. I honestly feel bad for the people that got defective ones because this thing is great. ... show more
