CyberPower EC850LCD Ecologic UPS Battery Backup and Surge Protector, 850VA/510W, 12 Outlets, ECO Mode, Compact, UL Certified

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 equipmentDesigned 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.

EQUIPMENTProduct: 450VAEquipment: 2017 27” iMac | 3.4GHz i5 | 40GB Ram | 4GB graphics cardINTROI am a freelance motion graphics artist and I work from home often, so I decide to buy this battery backup system (450VA version) as a safeguard in case of a power outage, giving me to time to save and close my projects. I have a 2017 27” iMac and I searched online to find out how much power this computer uses and estimate how long it would take for my computer to shut off. I couldn’t find a definite answer so I decide to purchase and do my own testing. Of course there are many variables in figuring that out as it all depends on the usage and how much power the computer is using at the time of the outage. If you are using your computer for browsing the internet at half of the screen brightness while not watching a video or listening to music, your power consumption will be a lot less than if you were editing heavy animated graphics at full screen brightness while using the speakers.THE TESTFor my first test I unplugged the battery backup from the wall and started the timer on my phone. On the iMac I had the screen brightness 3 dots away from full brightness and I had Adobe After Effects rendering a 10 second medium complexity animation project at a third of the resolution.- When I unplugged the battery backup from the wall, I heard 2 beeps - letting me know that the system is now using the battery.- The two beeps kept repeating every 30 seconds, probably as a reminder that I was still running on battery.- At 2 mins and 40 secs I heard several beeps - I am assuming that the battery was at 50%- At 4 minutes several beeps went off and did not stop.- At 6 minutes and 35 seconds, the iMac shut off by itself.CONCLUSIONThe product seams to be of good built quality, I like that all 8 outlets are surge protected and only 4 of them are battery backed up. At about 6 minutes of power after an outage, that works perfectly for me. I don’t need to be working during a power outage and 6 minutes is plenty of time for me to save my projects and not loose any work done. For the price, that is a small price to pay for huge peace of mind. Now, if you need to be working through a power outage or if you will be using a bigger power load with more equipment using the battery’s power, I would advise for you to get a battery backup system with larger battery capacity.

I must say, I have purchased several other battery back up systems from Cyberpower before and they are always flawless. This particular unit I use to power my cable modem/router, Majic Jack Device (IP Phone), Cordless main phone, and two IP Security cameras. It will power all of that for 90 minutes if the power goes out. how do I know? The display tells you so! Here is the rest of my review.1) Quality. There is never a problem with quality in the CyberPower brand. Everything is built well. 5 of 5 stars2) Display. The display tells you everything you need to know, like how much time before the battery back up is drained. Also how charged the battery is, and more. Bravo! 5 of 5 stars3) Hang on the wall. I use this in my data closet and can easily be mounted right to the wall. I mount it about eye level so I can go in and see the display when there is a power outage. 5 of 5 stars4) Outlet config. There are 4 regular outlets with surge suppression, and another 4 with additional battery back up. Perfect for my needs. 5 of 5 stars.This unit is an awesome addition to my home network and securty system. I highly recommend the unit as described in my review. If you are looking to power a PC, you might consider a unit from CyberPower that has a larger battery capacity. This powers the router, two security cameras, and the IP Phone very well. Another reason why I use this is because in my area we get small power bumps that last only a 1/2 to 2 seconds once a week or so. My IP based security cameras get thier internal clock reset when this happens causting the day/night function to be incorrectly timed. The battery back up maintains the power and the clock function in those cameras so I dont have to constantly be resetting the clock in each one. Other benefits is that I will have power to those cameras when I have a power outage.
