  • Excellent UPS Works Flawlessly During Power Outages
Style: 850VA LCD Pattern Name: UPS
My go to for UPS supplies. I have several of these units protecting my most important electronics. I have used these extensively during power outages and I can say with confidence that they will not only protect your electronics, but also keep them running for a brief time. These are not meant to power your whole system for an extended amount of time. This is only so you can safely power down your devices. Another great feature of this device is that when the internal battery reaches its end of life, replacing it is extremely easy. It’s as simple as buying the battery and installing it with only two screws. I would give this CyberPower UPS five stars. It is so easy to use and I like the LCD screen too. Lots of features like overcurrent, undercurrent and voltage etc. protection. Super great price on these too. Unless you’re using a huge amount of wattage, you probably don’t need one of the bigger units. These handle my entire Uplift Desk and Mac mini and tons of other audio equipment Designed flat to easily lay on the floor. It’s also designed so the outlets are spaced apart which makes large plugs easier to use. It is also made to easily replace the battery which is much more difficult on the larger UPS. Hope this review helps you in your choice. ... show more

  • Simply this backup battery works. I recommend this product and own a few
Style: 850VA LCD Pattern Name: UPS
Simply this backup battery works. The user interface isn't the most intutive to use but it's not hard either. I live in the middle of nowhere and power went out 84 times (most brief outages) and without fail this little unit kicks in and kept the electronics from resetting. The beeping isn't too bad when the power goes out as some are. The beeps are spaced a good amount apart to remind you power is out, but not so much you want to shut the battery down because it sounds so annoying. ... show more

  • Protect yourself before disaster.
Style: 850VA LCD Pattern Name: UPS
I had a previous cyberpower ups without a screen and for some reason the battery stopped working and a breaker flipped and my computer went out the second the power did which didn't make sense until I realized the batters couldn't hold a charge after 7 years. My pc started having problems after where it wouldn't take my old Ram overclock of 6400mhz now I can only go to 6000mhz without getting constant bsod. I upgraded to this for the screen and the outlet layout. I don't like the tower ups because the outlets are too close together while this one lays on the ground flat and has space for bigger power bricks. Can't recommend a ups enough if you have a computer or nas. Invest in protecting your electronics plus have battery backup just in case of blackouts. I can't run your computer for long but if you quickly turn everything off you can at least have enough juice for your phone to charge if it is an emergency. Think ahead and start protecting your electronics because so many people have all their pictures and information on their computers and one bad shut down or power outage can ruin your computer. Rolling energy outages may soon become more common. ... show more

  • Reliable backup power; loud alarm and short cord
Style: 850VA LCD Pattern Name: UPS
Why I ordered this item: My office is on a weird circuit that flickers during storms, and I've lost work before when the power just cuts out. I wanted something with enough outlets to cover my monitor, PC, and a couple peripherals. Likes: * This thing kept my desktop running for a good chunk of time during a real outage last week. Long enough to save everything and shut down clean. * The LCD screen is snazzy. It shows the load percentage and battery status right on the front so you're not guessing. * Twelve outlets total is a lot. I've got my PC, monitor, router, and a lamp all plugged in and still have room. * The eco outlets are kind of funky. They cut power to my speakers and printer whenever my PC goes to sleep, and I didn't have to set anything up for it to start doing that. No likes: * It beeps. Loud. Every time it switches to battery, and there's no way to shut that up quick if your kid is sleeping in the next room. * The cord is short for how big this thing is. I had to move my power strip setup around just to make it reach the outlet. Would I pay full price for this product: Yes Final thoughts: This is a good pick for anyone running a desktop setup that can't just drop offline mid-task. The eco outlets are a snazzy touch since they cut power to stuff automatically when your PC sleeps, and the display gives you real info instead of just a blinking light. ... show more

  • Re: UPDATED!!! Read last paragraph
Style: 850VA LCD Pattern Name: UPS
****READ THE BOTTOM PARAGRAPH FIRST!!**** This units were plugged in for more than 4 months, they both were fully charge at 100%. Once the electricity went out due to the hurricane Milton, the battery pack never started to work after the power outage, I had to use a flashlight to upload the video below showing the unit not working as they advertised they supposed to work after an outage for 52 minutes! If you have electricity the unit will show 100% charge, once you get an outage, the units are dead right on the spot. I will update my review after the supplier responds to my emails and phone calls. Hopefully they make it right because I bought two (2) battery backups and paid a lot of money! *****UPDATE***** The supplier contacted me today 10/14/2024, after they look at both serial numbers of my two Battery Backups, they told me those two battery backups were BUILD / MADE in the early year 2023 NOT 2024. The supplier also said that AMAZON should of NEVER hold on their storages old battery backups because these batteries needs to be sold right away after they make them and if these batteries backups are sitting on a storage for so long the batteries eventually won’t work at all and I needed to do a disposal of both of them and the supplier is sending me two replacements battery backups at no cost this week. I ASK the supplier to please; A- Do not sent me any used one or any recycle ones and B- Do NOT sent me a new one that was made a while ago to please send me a new one made this month, this year model. The supplier agree and they even sent me an email as a receipt to dispose of the batteries. LAST UPDATE!!! Received two new batteries from the manufacture as they promised. All good and the date and year is 2024. ALL GOOD! Kudos to the manufacturer who took take of me as a new customer!!! ... show more

  • Beware of "incompatible waveforms"
Style: 850VA LCD Pattern Name: UPS
Adding my voice to the several others here for cautions about this unit. Apparently, if your PC has a graphics card or an 80 Plus certified PSU (which, frankly, all PCs should have these days), you want the Active PFC line of products instead. This unit uses simulated sine wave technology, compared to pure sine wave in the Active PFC line. How did I find this out? Well, let me tell you about *my* CyberPower experience. I've had the unit for about 4 months now. I've noticed that occasionally (maybe once a month or so), the unit will switch to battery power for about a second, then switch back - just long enough to reset the digital clock plugged in to one of the "surge protection only" ports. This usually happens overnight, while my PC is on, but idle (not "sleeping", but idle). The PC remained on, but the clock didn't. There was no beep at this switch, but I definitely heard the click of it switching sources. I decided to use the included software to "initiate a self-test to ensure unit is working properly." The second I clicked that button on the software, my UPS unit shut off WITHOUT the battery (fully charged) kicking in. Somewhat perturbed (and disturbed), I turned the unit back on, and then turned my PC back on. Or rather, I tried to turn my PC back on; no such luck. With some guidance from techy friends (and some computer repair experts), I've established that the dead component is NOT: hard drives, video card, RAM, or internal power supply (PSU). That pretty much leaves either the CPU or the motherboard. With this knowledge in hand, I initiated contact with CyberPower. The online form was easy enough to fill out, and I even got an email response in about an hour, asking for more information (9 questions, the first four were generic about the UPS usage, and the other five were about my PC) and some simple troubleshooting steps. Yeah. Like I can really troubleshoot anything when my PC won't turn on. Anyway, I responded with detailed information within 2 hours, then sat back and waited to see what they would say. And waited. And waited. I ended up calling their 24 hour support line, where I waited on hold for the expected 30+ minutes. I gave the technician my case number, hoping to get advice on exactly what info they needed/how they would cover my PC failure, and the gist of the conversation was "I'll let the person who opened the ticket know that you called to follow up 8 hours later." This morning, I was excited when I finally received another email from CyberPower (about 22-23 hours after I submitted my form on the website). It was very detailed about possible waveform incompatibility between the unit and my graphics card, and how I should look at the Active PFC product line, and contained zero acknowledgement that my PC doesn't turn on. Meanwhile, my computer is sitting in a 6-day-long repair queue at MicroCenter, just to get the official diagnosis of whether my CPU or motherboard is fried, and I have all my new PC parts already planned (because if the CPU/mobo needs replaced anyway, might as well take the opportunity to upgrade), but I have to wait a week (+$40) to get the diagnosis first, because CyberPower will *probably* require it for proper documentation for the warranty to take effect. I'll update this review with the conclusion... Once I have one. ... show more

  • Good UPS for a desktop PC/Mac if for nothing else but surge protection.
Style: 850VA LCD Pattern Name: UPS
Good UPS for a desktop PC/Mac if for nothing else but surge protection. Well made and seems as sturdy as an APC. Hopefully, batteries will be available in the future. It's a good idea to change out batteries every 3 years, and replace the UPS after 6-7; less surprises that way. Recognized by Mac and PC alike and only need to use the built-in battery utilities for auto-shutdown. ... show more
