5.0 out of 5 stars Great for powering LED lamps during a power outage! SILENT MODE much appreciated!

CyberPower CP825AVRLCD Intelligent LCD UPS...CYBERPOWER SYSTEMSI bought one of these March 17, 2011 to replace an older smaller unit that I used for running my modem, router, & two Compact Fluorescent Light bulbs. I had been using a GEEK SQUAD 1500 VA UPS for my old PC, but when I replaced it, I put the new one A Dell Optiplex) on the other side of my desk & connected it to this CYBERPOWER UPS. I was very surprised to see the estimated runtime was no less than 30 minutes, even with the PC, 1 CFL, the modem & router connected & running. The monitor & amplified speakers are still connected to the GEEK SQUAD UPS.Where I now live, the AC power is very reliable, & we rarely lose power. Yet, last night, power failed; though it took me a while to notice it, because the light was running on the UPS' power & the UPS alarm had been set to silent. I suppose it was at least 5 minutes before I shut down the PC, which I did only because the GEEK SQUAD UPS was very old, and signaling immanent battery failure, & a PC without a monitor is no fun. It was at least another 5 minutes, maybe even 10 before I unplugged the modem & router. This unit gave an estimated runtime of 75 minutes after I unplugged everything but the CFL. Yet, this UPS continued to run my CFL (equivalent to an incandescent 100 watt bulb) for nearly 2 hours. I was able to read with more than enough light until the last 5 minutes, when the unit began beeping. It has a silent mode that defers the audio alarm until then.I am very satisfied with this unit, and expect that with the infrequent loss of power in this neighborhood, its internal battery should last more than another few years (it is 3 already). While it is a bit too low in capacity to run a PC, monitor, speakers, etc., for more than about 15 to 20 minutes, for my application, it works fine. I noticed that my new PC, though much faster than the old one, appears to use much less power. As I need to replace the old GEEK SQUAD 1500 VA UPS, I might consider a CYBERPOWER 1200 VA unit rather than the 1500 VA one.edit:While this unit does not have PURE SINE WAVE WAVEFORM - ACTIVE PFC COMPATIBILTY (see the COMPARE PRODUCTS table), it does run my new Dell PC (bought just this year) just fine -as far as I can tell- from a mere 5 minutes or so.Summary: I leave this unit turned on at all times, and greatly appreciate its SILENT MODE; no more groping around in the dark when the AC power fails, as this runs the CFL for nearly 2 hours, & I suppose it might even last longer if the CFL was the only thing plugged in to it. If I lived in an area where the power fails frequently or for longer durations, I would want a more powerful unit for this purpose, perhaps even a 1500 VA one.This recent outage did last an unusually long time, about 3 ½ hours, and though it was already dark when it started, the important thing is that it did not take me by surprise. I was not suddenly left in the dark, groping for a flashlight. Although the UPS did run out of power after about 1 ½ hours, I was well prepared for it, having plenty of flashlights, lanterns, & fresh D-cells on hand.If I were choosing a UPS for running my PC & monitor, I would definitely want a 1500 VA one, if only because I would want no less than 45 minutes while running on the battery. As of right now, the estimated run time is 36 minutes, though as noted above, my monitor is plugged into another UPS.=======================================================EDIT 07/12/2020It is still working!I looked at my AMAZON purchases page, and realized just how long ago I bought this! Although it still works, it would really inconvenience me, if it died. So, I just ordered a new one. I no longer use CFLs, but, LED 3 ways. 1 of which will be plugged into the new UPS. I do expect the old one to die eventually, & want to be ready for that.While I thought about an APC instead of a CYBERPOWER brand, it was because of some very poor reviews of this particular unit. But, it seems that similar APC and TRIPP-LITE units also have some very poor and recent reviews. I will stick with the familiar, for now, anyway. New unit will arrive 07/15/2020, & I expect it will work fine.

excelente calidad

Esta producto cumple con mis expectativas, si te quedas sin luz, te deja terminar el trabajo.

Excelente equipo de respaldo de energía.

El equipo ya pude ponerlo a prueba por primera vez y funcionó mucho mejor de lo que esperaba. Lo uso como respaldo de mi teléfono e internet y duró más de 3 horas. Si hubiese prendido mi TV y decodificador, habría soportado cerca de 1 hora. Lo bueno es que si quieres evitar el ruido de la alarma por uso de la batería, tiene opción para apagarla.

5.0 out of 5 stars Worth It for the Peace of Mind

I wish I'd bought this device a long time ago. I live in an area that gets frequent power blink-outs when it's windy, or hey, even when the weather is sunny and calm. Just a few seconds - long enough to knock a computer off. (Yes, we live in the 21st century if you can believe it, but the power companies haven't apparently caught on to this fact.) :KSet-up is very simple: four outlets for battery backup, and four for just the surge protection. Realistically, because of the size of some plugs, you might only be able to use three on each side.Unfortunately, since I got this thing I haven't had any power blink-outs! So I can't for certain say it works or not for those. Maybe it's my lucky charm? :) The $85 I purchased it at is a lot of money for me, but I can say wholeheartedly that it's been worth it just for the peace of mind. And this is no dinky piece of plastic. It's a sturdy, hefty 14 pounds, positionable on its side, on end, or flat. It can even be mounted on a wall if you wish.It's tough, when shopping for a UPS, to decide what kind of power you're going to need against what your computer uses. I pretty much had to make a semi-educated guess when choosing for myself. If it helps any, for the 825VA 450W model CyberPower UPS, I got it for a computer running a 6-core processor, 650 watt power supply, mid-range graphics card, 6 fans.... I have the PC, 17-inch LED monitor and DSL modem plugged into the battery backup plugs (scanner and printer plugged into the surge protection-only ones), and with a browser open running a graphics intensive game, it says I have around 25-35 minutes of backup power. More than enough. I really only need 5 to determine whether the power is coming back on or staying off so I can shut down my computer properly.Really, if you have electronics you care about and can't afford to have get fried or constantly knocked off by power interruptions, it seems worth it to have one of these. :)** Update: August 2013I finally lost power (yay?). Weird, I was always having minor to major power outages here before getting this... Anyway, it was only out for a minute or so, but it was a complete interruption, and this UPS kept my computer system running without a hiccup. Gave me a beeping alert that there had been an outage and the LCD screen lit up. That's about it! Felt funny writing a review for a UPS without having seen it actually back up power, and now I've seen it do its job. I'd never go without one of these for my computer again!

4.0 out of 5 stars Has everything you will need - unless you need true sine wave

2026-03-06    -Christopher J. Dean

This is an excellent unit for the price. The only way it could be better is if it is true sine wave as opposed to the modified sine wave...but those cost more and you seem to have to give up features (like being Green). This one has hot swap batteries, surge protection, AVR, coax protection, digital readouts, and most importantly it saves power because it bypasses the inverter if it is receiving a good power signal. For me that was the most important feature. It won't power everything because it is not true sine wave but basically anything that has a power brick or transformer should be fine. I use it to power an airport extreme, time capsule, and cable modem and it works great.

Great protection for your computer and router systems

We purchased this identical power bank about seven years ago As we were having power spikes in our power grid down our street killing our Wi-Fi routers. Once we hitched up to this power bank, there were no more issues with our routers dying As the power comes from the power bank, not directly from the power grid.This will be the second one we own, and I expect that it will be just as good as the first one.

Excelente producto

El primer párrafo es meramente informativo, a partir del segundo es la reseña del producto en cuestión.Primero hay que mencionar que no se debe de confundir con otros equipos para la administración del consumo de la energía eléctrica, tales son el Supresor de picos y el Regulador de voltaje. El UPS (No Break) comparado con estos dos, posee sus características combinadas con la ventaja de tener integrada una batería (pero supone un mayor costo debido a esto), la cual le permite continuar utilizando sus aparatos por un breve periodo de tiempo, para que pueda apagarlos correctamente. Si en lo personal, no desea tener este "respaldo" al momento de que se le vaya la luz, le recomiendo que revise las otras dos opciones que mencione, y vea cuál se acomoda más a sus necesidades.Hablando ya del producto, he quedado más que satisfecho con el rendimiento que me proporciona. Lo he estado usando desde el momento que me llegó (aproximadamente 3 meses), y en ese tiempo no he tenido problemas con él. Se me ha ido la luz en varias ocasiones, y he podido continuar trabajando y apagar correctamente mis aparatos, sin problema alguno. Lo que más me ha gustado, es que se puede conectar a su computadora por medio de un cable incluído en la caja, lo cuál le permite monitorear, desde un software como panel de control, el estado de su equipo y configuración así como el consumo energético y contaminación producida.Recomiendo seguir las instrucciones de instalación y configuración que vienen en la caja, para que tenga un óptimo rendimiento su equipo.
