Perfect for my application
Style: Compact
Size: 550VA
We have a small Haier thermoelectric wine cooler and use it to store a few "better" bottles we want to keep. The one problem it had was after even a brief power "flicker", the unit would go off and stay off. "Flickers" are fairly common in our rural area, so we were always afraid that we'd come back from a trip and find the cooler off and our effort to keep it at a constant temperature defeated. This week, following a severe thunderstorm, the power not only flickered, but remained off for an hour. The UPS unit kept the power on and the temperature steady for that time. Obviously it wouldn't last forever on battery, but we feel better that a brief outage will not affect it. I have not had the opportunity to test the other features of this model like computer shutdown and connectivity.

UPS
Style: Compact
Size: 550VA
My main use of this product is for simply, Battery backup so that I can resume my work without interruption of a power outage (even though I have a laptop, but my newly built desktop is on standby) It had a weird smell once I opened the box but its not bad, that means it was freshly packed (In my opinion). The software was great, just what I wanted. All I have plugged in is my Cisco router, and my almost completed desktop. I have lots of room in the built in outlets for future expansion of my workstation. Highly recommend this product for people with computers or if you just want general protection for your TV, Video game, etc.. This is my first time with this company. NOTE: You must charge your battery for 8 hours before use, you can use it while its charging but I wouldn't recommend it. But that,s your call. Shipping was very good (even though it was raining and whoever placed the package into a plastic bag didn't tie it properly.. but it is in working condition and it didn't get soaked.) Update: 8/18/13 I went away for vacation for a week and when I came back, My computer wont turn on, I checked and noticed the ups was off and I left the ups running for a whole week when I was gone. I tried turning it back on and it wont. I called Cyber-power tech support and followed the steps he told me. I pressed and held the power button for 5 seconds as he requested and it still did not turn on. So he sent me a email and I have to provide the information and the invoice for the return shipping label free of charge and when they received it, they will send me a new one at no cost. 5/5 tech support right there. So now I have to use my laptop in the mean time while I wait. But I'm still wondering how and why my ups was off and why it didn't turn back on. Update 9/10/13 After all the wait, I emailed cyberpower and they said that they were doing their biannual inventory check and all orders in and out were frozen. I didn't mind but Id wish they would have sent me a email letting me know. But hey the replacement came and I received 2 cyberpower units, which ill keep the extra one as a spare. I'm loving the replacement so far and no Issues has arisen ever since. Thank you Cyberpower! Looking forward to doing business with you in the future.

Solid Hardware Inferior Software
Style: Compact
Size: 550VA
Solid product all their residential units. CyberPower Power Panel software to monitor need improvement. Here is the issue... Thr "64-bit" PowerPanel Linux software is just a 32-bit binary wrapper. It forces Linux users to install legacy multi-arch libraries just to get a UPS status. Need to compile true 64-bit binaries! It's old and hasn't been updated in years. They need to improve the software.

Good unit, but it depends on your use.
Style: Compact
Size: 550VA
Been using Cyberpower UPS units for years, they are extremely reliable and bought this one to use on a new computer. Under normal circumstances these units can handle a computer and even a small monitor without issue. But this new computer is a 14700k which is known to be power hungry and also a large graphics card. At times where the computer is running hard, it can overwhelm the UPS which sounds a tone when its wattage is surpassed. So bear in that in mind when buying. If you're running a newer desktop, particularly Intel, this may not be enough to handle it. That's on me, not the UPS. I did not mark it down based on that, just putting out the information based on my experience. Still, a good unit and Cyberpower is probably the best out there. For laptops and other applications it should be fine.

Excellent Battery Backup AND Software
Style: Compact
Size: 550VA
Backing up a computer and 20" LCD monitor, I got about 15-20 minutes out of this unit before it told the computer to hibernate. I'm using this throughout our office, since our power here is often flaky. If you run a business environment, goto the Cyberpower website and download the "Business Edition" (free). It has three modes you can install, and the Agent mode basically installs a small web information panel on the client computer that you can pull up from anywhere on your network. APC wants me to pay big bucks for this sort of functionality, and Cyberpower gives it to me for free. Cyberpower FTW! At one time I valued the ability to replace the battery on a UPS like this. However, these days the upside of doing so is minimal, especially since most manufacturers will not pay for shipping any longer. Just replace the whole unit every three years, since the components inside will degrade over time anyway, and take the old unit to an electronics recycling center.

Keeps my internet up 24/7
Style: Compact
Size: 550VA
I have several cyberpower power supplies from the 350 up to the 1350 and have no negative issues. Three are at my beach house on the Washington coast where the power is interrupted all the time. If the power even goes off for a second my security cams lose connection & the system must be rebooted and this kicks in so quick they never go down anymore. I'm totally happy with this product backing up my modem/router/dvr,satellite box and security cams.UPDATE-- I have my modem in my water well pump house & it's been plugged into a cyber power supply for two years. In the summer it's scalding hot & humid and winter cold & harsh. The supply hasn't skipped a beat thu several power outages. I do unplug it to run the battery thru a discharge charge cycle and that seems the keep the battery healthy. My phone is voip so that system is also backed up & never failed to work during power failures.I have three Cyber Power power supplies and all three work just fine. I will buy more from this manufacturer in the future if needed . I don't accept products in return for my review.
