CP550SLG Standby UPS Battery Backup and Surge Protector, 550VA/330W, 8 Outlets, Compact, UL Certified

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.

This is perfect for my needs. It has enough battery backup time for me to save my work and shut down my computer if there's a power outage, and it bridges the gap nicely when the power just blinks off and on. You can connect it to your computer with a USB cable and monitor your UPS or change settings using the free software. All in all a good value.

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.

Don't get the CP550SLG, get EC650LCD. I've bought both, the problem with CP550SLG is it has a pretty custom battery which is expensive to replace. CP550SLG battery costs roughly 36USD and you can only get from a specific vendor. EC650LCD uses a common battery size, sold by multiple vendors that goes for <20 USD. If you plan on having and servicing this UPS for more than 3 years (around 1 battery replacement), you'll save money buying EC650LCD.

Does its job. 18 minute back up time. For Xbox. Modem and router.

I bought this unit for my computer and mainly my router. With everything streaming including security cameras power outages even slight ones meant I had to reset TV's Camera's and Echo's. The unit says it will last 83 minutes with the wattage I have connected. That is plenty of time for recovery. My first test came last night when the electricity flickered on and off which effects the router and all streaming devices. With the UPS all my equipment reconnected with no problem.

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.

Recently I bought this to protect my new rig I bought. I usually just use a regular power strip, but I was afraid of blowing up my new fancy computer. One day I was in my house, doing my regular thing when the power went out. It started doing the loud beeping thing (which by the way, it didn't even keep my computer on like it was supposed to, for even a second) and then I just kinda sat there. I smelt burning, and I was really scared. When the power came back, my computer turned on fine, monitors alright. I was relieved. But instead, it turns out it blew something in my subwoofer because now it didn't work at all (after extensive testing, it is definitely the subwoofer, not anything else, audio jacks, etc.) It wasn't even a lightning storm, or anything. I've had power outages all the time. So I got kind of angry that it just kind of decided to blow up the circuits in my sub for basically no reason. I set up a warranty thing with Cyberpower. I sent them an e-mail and they decided to tell me to just call them soon. I did all of this within the required 10 day period. I called them, asking about my warranty. The woman on the phone just says "what? WHAT?!!?" as if she were losing service, but she was really angry. I called back after she hung up within 5 seconds of me calling her. It went straight to voicemail after a ring or two. I called her one more time, instead from a different place thinking it was service issues (which I don't usually have, but considered her location) and once again, straight to voicemail. No followup from them, nothing. Now I have to use a separate powerstrip AND this UPS, because for some reason the battery on the UPS (that didn't even support my computer) is already near dead, and I can't plug in more than a few things into it. It has shut off my computer due to excessive power usage more than 3 times, which is more than the amount of times it's saved me from a power outage (0 times). I just ended up getting new speakers from a friend because after being shunned that day, it was beyond the 10-day period, AND I just wasn't having it. Next time I'm going to try to buy from a better company. Considering recently I purchased a router from a company (MediaBridge to be specific), e-mailed them with a question about the router messing up rarely, and they sent me a BRAND NEW ONE NO QUESTIONS ASKED, I can see the difference in customer service that CyberPower was really lacking. I saw warnings on the internet, and as a poor college student I should have taken that into more account.
