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 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.

Works great, good battery life, easy setup, too. You have the choice to hook it up to a computer through a USB port to control the software, but it's not required for it you to use it. Definitely good value for the cost.

****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!!!

Works great! We had a power outage I thought this would last awhile to listen to my scanner when power went out. It only lasted 2hrs. The scanner doesn't draw that much current.

Works exactly as described

I have three of these with one for all of my expensive electronic devices. Before this I lost two computers at different times due to power surges when the electricity went out in my house. It cost me $2,000.00 to replace the computers plus countless hours setting them up.. Now I have never lost another device due to surges. Everyone should be using these.

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.

CyberPower EC850LCD Ecologic Battery Backup I bought this small battery backup UPS in order to have uninterrupted power during a brownout or a short blackout, for my modem , router, mesh master node and file servers. Are all fairly low-powered devices so a small battery backup system like this can easily handle the wattage requirements for these networking equipment. I get a lot of brown outs throughout the year and every time that happens something funny goes on on my network. The reason I decided to get a UPS like this is because the recent brownout caused a TPlink access point to "fry" or get corrupted and it was very difficult to restore . A simple UPS like this going to save me a lot of time in the future. I love that it has a mini display that shows you the number of minutes left in the battery. Gives you a really good idea of the power utilization that's attached to the UPS. Works fantastic. And by the way, if you were to use this on a PC, it comes with a USB connection so that you can direct your PC to shut down in the event of the power outage. Personally, I don't use this functionality.

Excelente produto, tengo 4 meses con el y me ha salvado innumerable ocasiones. Donde vivo es muy común que con cualquier lluvia se vaya la luz o se corte un instante, suficiente para apagarte la computadora. Tengo mi PC gamer con un monitor conectado al aparato y de todas las veces que me ha salvado de cortes de luz yo creo que ya se regresó la inversión. Completamente recomendado.

Parfait! Il fait exactement le service et il fonctionne très bien. Cing étoiles et reçu plusieurs jours avant la date proposée.

Compre este modelo después de que varias unidades economicas resultan insuficientes o terminaran muriendo rápidamente, y estoy muy contento con la compra. El diseño es muy practico ya que permite conectar multiples dispositivos con conectores "gordos" que de otra manera terminaría ocupando el espacio de otro enchufe, además permite conectarse a en equipo de cómputo para monitorización directa y no tener que depender de andar interpretando los pitidos cuando algo anda mal, soporta 6 dispositivos protegidos con bateria, y 6 con protección de voltaje, de los cuales 3 se pueden configurar en modo ECO de tal manera que se desactiven si tu PC de sobremesa (en caso de que tengas una) está apagada, optimizando mas el ahorro de Energía. Lo único negativo, es un problema que todos los UPS tienen en México, no tienen garantia por daño a equipos electrónicos, no los culpo, con nuestra "Empresa de Clase Mundial" yo tampoco me animaría a ofrecer este tipo de servicios, pero a final de cuentas es algo que merece comentarse.

I had an issue with mine where the battery-supported outlets stopped working, but I got it replaced with their warranty in around 1 week. It was an easy process, so I rate their customer support well. As for the device itself, it is decent, but I wouldn't use this for a computer. When I measured the watt usage on my computer, it was a max of 435 W while gaming. I know there is some inefficiency here and it's not exactly 1:1, but I would expect this UPS to be able to handle my computer. Unfortunately it can't, so I only get to plug in low-power stuff like my router. It also behaves really annoying when you're close to the limit of the UPS. It's a loud, constant beeping that you can't mute. I do get it, make me aware that it's a problem. But I wish I could mute it while I turn off my devices and unplug them.
