CyberPower CP1000PFCLCD PFC Sinewave UPS Battery Backup and Surge Protector

1. True sine wave power: Electric power is not highly reliable where we live and I wanted to replace my aging APC back-up power supply (or Uninterruptible Power Supply / UPS) after I got a new computer (Apple Mini). Purely by accident while researching what to buy, I noticed in the always-valuable Amazon user reviews that some computers require the AC power provided while running on battery to be a true sine wave but some UPS units just approximate that with a squared wave form. It doesn't matter if you understand this or not, the point is that increasingly, newer computers need power of the same quality that power companies provide, even when operating off the UPS battery, and many (most?) UPS units do not provide it which can result in erratic or no computer operation, so you should be aware of that. No computer accessory store, nor Support for my new computer, knew this, very odd. To their credit, Apple support checked back with their Engineering department and provided me with a solid answer, and I found that yes, my new Apple unit required true sine wave. APC, arguably the best known maker and who I had used before, makes such units, but they are far more expensive than the usual APC units someone would buy for personal use. I shopped around, including via the aforementioned Amazon user reviews, and found CyberPower, who makes several very reasonably-priced UPS units with pure sine wave power, bought it, and it works well. Bottom line on this topic: You need to find out if your computer needs pure or true sine wave power (meaning, if your computer has a "power factor corrected" or "PFC" power supply) and ensure you get a battery back-up with that feature if so. Apple informed me that all of their recent desktop units have PFC power supplies and do require true sine wave battery back-up if you choose to get a back-up. I am not sure if getting the wrong battery back-up unit would always or just potentially affect performance and/or durability, but obviously you should get the right unit for your computer or other devices and not find out. 2. Rating: I've only had this unit in service for a short while so can not comment on long-term reliability, etc., but so far it works well. My unit is a little oversized to provide capacity for adding future items, for longer operating time on battery, and to provide some cushion for when things are starting up . It provides surge protection, regulated power (holds voltage to computer steady), and of course battery back-up. The product comes with a disk for Windows users, but nothing for Apples, so I do not know what additional bells and whistles appear for Windows users, but I can comment for Apples: The installation is ridiculously simple, just plug in the unit, connect the computer and UPS via a USB cable (have U had enough U's yet?), turn both on, and the Apple software (under System Preferences / Energy Saver) automatically recognizes it so you can set things up (e.g., during a black-out, run on battery until battery has x-minutes of life remaining, etc.). The printed instructions are light on connecting to the computer and such, maybe more is on-screen if you are a Windows user and can use their software, and Apple users will find even less info, but in the end, CyberPower's Support was helpful and clear and it's really simple to do. CyberPower also has a Beta-version of energy saving software but I did not install that and they indicated it provides no crucial or needed functions, just use the Apple energy management software already on your computer. So, a good experience so far: easy installation and it works. I hope they eventually provide a bit more guidance and insights for new users in their printed instructions, especially for Apple users; It may be simple but if you're a new user and/or like to know for sure before powering up electronics, they need to provide more. Other than that, it's operated well and already protected my computer from the wimpy power company during a storm. Amazon's pricing was as good or better than other sources and Amazon's customer support is always something to count in your decisions compared to other sources. I liked my old APC unit but this CyberPower unit is also nice, and provides the required sine wave power at a cost much lower than APC does.

I purchased this unit for my Mid-2011 27" iMac / 2.7GHz i5 Quad-Core / 1 TB Hard Drive / 16 GB RAM (Self Upgraded) / 512 MB Video/Graphics. The main reason I purchased this unit is, well, because in my opinion, if you have a desktop computer you absolutely NEED some sort of battery back-up unit, because power failures/outages WILL happen. Not to mention, brown-outs, where the voltage drops to an unusable level. The only time I would really say that you don't absolutely need a battery back-up is if you have a laptop, as they have built in batteries obviously, which will prevent it from doing a hard destructive shut-down with loss of power. Though if it were me, I would still purchase a battery back-up, because most of them feature AVR (automatic voltage regulation), which levels out the power output without having to resort to using the battery's power supply. For example, if you have a high load being drawn on that circuit, or for some reason your voltage drops some (not too much of course), this unit (and some others) will compensate for that and give you a more constant amount of voltage. In my area, here in Florida it's pretty common to have outages, especially during storms and such. The most common outage is a very quick 1-2 second outage, and then the power will come back on. Which isn't great at all, it actually sucks, very much. I had JUST purchased my iMac and I was shopping around for Back-UPS units, when my house had a quick outage, and my brand new 27" iMac did a hard shut down. Which gave me sort of a kick in the pants and coaxed me to purchase one VERY soon and ship it VERY fast. I was considering the APC Smart-UPS units, but they were outrageously expensive. Yes I realize that you pay for what you get, in some cases, but I just didn't want to spend $500-$600 on a battery back up. I absolutely needed a unit that provided Pure Sine Wave power when on battery power, because the newer iMacs all have PFC (Power Factor Corrected, I believe that's what the abbreviation stands for) Power Supply, and your average Back-UPS units like the APC models that you find at Staples, Office Depot and Wal-Mart absolutely will not work with computers that have these power supplies. This is because those Back-UPS units provide a "Stepped Approximation to a Sine Wave" when they are running on battery power", and newer computers, both Macs and PCs, with the PFC Power Supplies will NOT run them when it's running on battery power. I was debating on whether or not to purchase one of these CyberPower units, because I've seen a couple bad reviews on them, but a very large majority of the reviews were in fact very positive and the people had nothing but good words to write about these units. I think a majority of the issues come from the items being mishandled during the shipping process. I witnessed this when the customer service lady at UPS basically body slammed my Back-Ups unit onto the table right in front of me as I was picking up packages. They really don't care, because you could see what the item was, as it was shipped in the manufacturer's product packaging. Which is absolutely fine so long as someone doesn't use it to kick a field goal, as the manufacturers product packaging box is double walled cardboard, with a very generous amount of foam and extra cardboard spacing inside. Even with the super body slam, my unit worked absolutely wonderfully, no fan noise or anything. The build quality of these units isn't QUITE as great as the APC tower type units that you'll find at Staples and such, the outer skin on the CyberPower tower units is slightly thinner than the APC units, though it's still sturdy and not at all flexible or pliable. Everything else is absolutely wonderfully built. If you shake it there are no rattles, when you press on various body panels on it, none of them are loose or incorrectly fitted, receptacles are nice, and everything is great. Menu/interface functionality is great, easy to navigate and very intuitive. The buttons are solid when pressed also. One very large advantage that this unit has over it's non Pure Sine Wave APC counterparts that you'll find in stores is that these units are SMALL. Nice, small, and compact. I would say about half the size of those APC tower units. Making it possible to place it on your desk if you would like, next to your computer tower (if your computer has one) or somewhere else on the floor. It will not take up much room at ALL. It will maybe take up as much room as a single size 11 shoe will, that's it. The performance of this unit is great. I witnessed a couple times where the power dropped some and this unit properly compensated for it without having to kick over to battery power. There were quite a few times where household power was lost all together and this unit provided a perfect, instant, flawless transition to battery power and if it weren't for the click from the unit and the light sound of the fan kicking on, you wouldn't know it switched to battery power. Unless of course your computer notifies you when you are running on battery back-up, which my iMac did. I had my unit set on the highest sensitivity, and it was perfect. Sometimes with other units you will have an issue with the units being far too sensitive to have it on high sensitivity and really protect your computer and fast, and you will constantly hear the unit turning on and turning off, which was the case with the APC non-Sine Wave unit I purchased from Staples a couple years ago for another computer, and I had to leave that one set to medium sensitivity. The unit comes with software that you can use to set up automatic shut downs via different determinations such as the amount of time your computer is running on battery back up, how much charge the battery has left, and other parameters. THOUGH, and this is very important! With newer Macs, you absolutely do NOT need to install this provided software, or use any other kind of third part software. This is because you can go into System Preferences, and into Energy Saver, and once you have the Back-UPS unit connected to your Mac via the USB cable, your Energy Saver settings will automatically give you options to set up the Back-UPS unit and set up automatic proper shut downs by different parameters, like battery charge left, time running on battery and such. So these CyberPower units REALLY integrate very well with Macs, which is a very large plus. Bottom line is, if you are looking for a very nice Back-UPS unit for your computer that has a PFC Power Supply, and you don't want to spend $500 or more, then you really MUST look into this unit. It is absolutely amazing, and the price is amazingly ridiculously amazing (if that makes any sense, lol). CyberPower also has higher watt rated models, up to 2000VA I believe, my unit was a 1000VA, which is like 600w or such, and when it switched to battery power, it would give me a run time of 34 minutes, which is great, considering I was running quite a few programs and such at the time. So if you have a similar set up, you will have no problem getting adequate time to properly do everything you need with this model. If you have a much higher end gaming computer or such, I would possibly go with the 1350VA, 1600VA or 2000VA model. I am about to order a new Late-2012 27" iMac (the new thin models) with the i7 Quad-Core / 3 TB HDD / 8 GB RAM (I'll be upgrading it to 32GB myself, which you can't do with the 21.5" models, oddly enough) and 1 GB Video/Graphics, and for this one I plan on purchasing the 2000VA model, which will do me just fine. ALSO, ANOTHER VERY IMPORTANT WARNING. If you have a laser printer, or anything else that has a very high current draw, DO NOT, I repeat do NOT plug the printer into the battery back-up provided side of the unit. Plug it into the Surge Protected Only side, or better yet, a completely separate surge protector strip, which is what I did. Because when you turn on the laser printer, or start printing, you will see the voltage drop on the display of you Back-UPS unit quite a bit.

I have been using CyberPower UPSs for at least 25 years. I have 7 in use at the moment, ranging from 200 to 1000 VA. Some backup my internet, security camera, satellite TV system and the main TV while others backup three computers and ham radio equipment ALL work as they should. Now to address this CP1000PFCLCD PFC Sinewave UPS : When I buy from Amazon I first look at how many reviews there are for product w/in a certain category, figuring the more reviews the more people buy that particular brand or model (12,000+ on CyberPower is impressive. I then look at the 1 star reviews to see what people don't like and the % of 1 star. If that % is high, I stay away. If low I try to see if there may be a real problem, if the item is being used for the wrong intent, not appropriate for the application or if someone is just a complainer. With the very low % of 1 star and high % of 5 star I felt confident in continuing with the CyberPower brand...I needed to replace a 12 yo 600 VA CyberPower that failed, given what I've put it through I'd fail too. I am thoroughly satisfied with this unit but I feel compelled to address some of the general complaints made by some of the 1 star raters....might help others in decision making. I saw a complaint that this unit doesn't stay on battery power long enough (run time) for his server with 6 PC to shut down. True, this is a UPS designed for home & personal use, not for a data center (if a person has a 6 PC server that IS a data center). Another commented that it doesn't stay up long enough to shut down his PCs running Virtual Machines as they can take more than 6 minutes to shut down. He choose this line of CyberPower because they are "cheap" compared to commercial grade UPSs. Again, that person is expecting a "home" unit to perform as commercial UPS costing 10x as much. Wrong application. A common misconception about UPSs is what they can electrically support. Suppose you have two UPSs one rated at 400 VA and another at 1000 VA and you have a 300 VA load on them. The misconception is that the 1000VA unit will run your 300VA load 2.5 times longer than the 400VA unit will. Wrong. Either will run the load until the battery is depleted. A typical 400 VA UPS has one 12V battery, this CP1000PFCLCD PFC Sinewave UPS also has ONE battery. The length of time any UPS can carry the load is dependent on the battery capacity, not the UPS VA / watt rating. In another 1 star rating the person complained that this unit which has a 500 watt load on it begins shutting down his system almost immediately at a power failure. Of course. It's simple math. 500 watts at 120 VAC = 4.16 amps . Since the 12V battery has to supply that 500 watts the DC current will need to be 41.6 amps (41.6A x 12V ~= 500 watts). First, the single 9 AH battery in this unit can't supply ~42 Amps. Second, the specs for this unit show the battery at full load is good for about 0.5 min, in the real world I think that is a generous rating. So, why would you get a 600 watt 1000VA UPS if it can't handle that much load on battery? The answer is for longevity. If you have a 300 VA load on a 400 VA rated UPS it will be working at 75% of it's capacity (as an AVR it is working even on commercial power) while with a 1000VA rated unit that same 300VA would be only 33% of capacity, it doesn't work as hard therefore should last longer. Similar as having two identical cars except for the engine, An under powered 4 cyl may be working at near full capacity driving down the highway at 75 MPH likely won't last as long as comfortably powered 6 cyl because the 6 isn't working as hard. There are two possible solutions to the short shut down time, 1) buy a commercial UPS designed for the expected load / run time. 2) Replace the low capacity internal AGM battery with a same size LiFePo4 battery, it more than doubles the runtime. Some say that can't be done....I've been doing it with great success for a long time. 3) Replace the internal battery with a higher capacity external battery. It is easy (given skill sets) to fabricate a wire harness to plug into the internal battery wires and run to an external battery. Going from a 9 AH internal AGM battery (which technically can deliver only 4.5 AH) to an external 20 AH LiFePo4 battery, which will deliver 20 AH, will extend the run time about 5x. The down side is when the LFP battery is 95% depleted it will go from full rated 12V to 10 V cut off in just seconds. Therefore under a full load condition on the UPS, you must initiate shut down as soon as there is a power failure (set the battery run to 0 in the software). At full load that would provide over 2 min to complete shut down (or hibernation) vs under 30 seconds. Would CyberPower approve of this? No. Would it void the warranty? Yes. Does it work? Very well. In my lighter load situation the AGM internal battery provides 8 minutes of run time. Replacing it with an internal LFP increases the run time to 32 min, enough to finish what I'm working on, save data & manually initiate hibernation.

UPDATE: Before the fire episode below, I had purchased several CyberPower UPS units at different capacities and Amazon doesn't seem to allow you to differentiate your review based upon WHICH size you purchased, but now SEVERAL of these units have failed. At least they didn't start a fire, but they are intermitten, sneaky failures where your computer or router or whatever you are trying to provide power to, will just stop working with no warning beeps or codes. The utility company power will be 'on' but the CyberPower will just shut down and fail to pass along the power company's power. It will later indicate the battery was full, but still, it just shuts down so that it is WORSE than if you had nothing at all ! It actually interrupts the power that existed! Terrible quality control apparently, or design defects. ORIGINAL: Like several others who have written in, this unit is a real fire risk. I happened to come into the room where my UPS was operating, sitting on a carpeted floor. I smelled a strong electrical fire odor and saw smoke in the room. I traced the smoke to the UPS and tried to turn it off. It just kept displaying 72 minutes remaining. I unplugged it. Still smoke and smell and the case was hot to touch. Its vents were not covered by anything, and it had "breathing room" and I could see the smoke coming out. The display stayed on. I tried the switch again. Couldn't turn it off. I decided I would have to remove the battery, but the door wouldn't open. I was getting worried with the heat and smoke it was still generating so I finally grabbed a screwdriver and chisel and managed to pry the battery door loose so i could remove a battery connection. THEN it shut off. About two months ago it began dropping power to my desktop so I had unplugged that CPU because my wall power was more reliable at that point, frankly; that left me running two flat screen monitors and the speaker amp for the computer. Enough people have had smoke or fire problems with this unit that a recall should be considered or at least directions for how to quickly remove the battery; otherwise people can be breathing the smoke and fumes in a small space (under a computer desk) while trying to figure out how to shut the darn thing down in a hurry, assuming they were home and lucky enough to spot the problem early ! I've written the company about the situation and asked if there is a recall out there somewhere. UPDATE 4-23-17: I emailed the company immediately, giving the facts and asking if any recalls, and within a day, an email reply suggested I call tech service. The unit was past warranty time but given the nature of the failure, I suggested registered owners be contacted ASAP with the quickest way to kill power to the circuitry if they experience what some of us have experienced. That's a reasonably inexpensive precaution, especially if panic resulted or someone doesn't have tools handy. Tech Support is having me return the unit for examination and supplying a replacement unit for the hassles, which seems reasonable. BTW, the battery seemed ok, once removed.

Working with my friend ChatGPT to setup a UPS to cover my Home Assistant, Modem, Router & POE switch. With a little work and help from ChatGPT I was able to connect this UPS to Home Assistant fairly easily & quickly. Note that plug spacing is tight, so for the larger power supply plugs, I purchased 1 ft 1625 watt rated extension cords, you can easily plug the clunky power supply plugs into those and the cord into the battery backup ports. Simple serial connection to Home Assistant. After a small integration with Home Assistant I now have power backup and it's monitored by Home Assistant. It's pretty heavy, but it is noiseless and provides predictable power backup. Battery life is expected to be about 3 hours with the power I'm drawing from it. Good Purchase.

As of writing this, the unit has been functional, and has been in action a few times with no significant issues and only a few areas for improvement. Wattage use: Throughout usage I have at most used it in brief bursts of ~500 watts, the highest it consistently is around however is a mere 300 watts, and at all times, it has made no fan noise that I have noticed. Backup use: On two occasions my house power flickered off for a few seconds then back on, and the UPS saved my PC from an unnecessary shutdown. Additionally, there was one time wherein my power company had a 3 hour long severe outage and during that time this UPS ensured I was able to safely shut down my pc, then use the remaining charge on the battery to keep my mesh router powered for an additional two hours. Unknowns: I have yet to test the ethernet port which I have heard may cause some packet loss, so I may update with results on that. I have not tested the additional "shutdown" software Cyberpower provides for use with this device so cannot attest to the quality of that, but out of the box software-only settings have worked great for me. While the power company does have rare outages and semi-frequent flickers, I have yet to experience any surges in 10+ years so cannot attest to it protecting my devices from surges, but have confidence in it. Phone Charger Ports Low-power letdown: I am slightly disappointed in the wattage of the "phone charger" ports (the front-facing USB-A and USB-C) as while they do reach what the specifications in their manuals say, a star is still lost as that is a good bit below standard for 2026, especially on a mid-range unit. Can be mitigated by plugin in a higher wattage charger on one of the outlet ports and using a cable with that instead, but that fills a slot that could have been empty if the phone ports were powerful enough. Outlet port spacing: High quality, with little to comment on for this, besides that the phone ports are a bit awkward for some use cases, unless setting this unit on the floor for example. Power cables of the UPS itself seem to be quality and have posed no issues with decent flexibility and length. Usability: Very easy to use, for more technical enthusiasts the one warning I have is to be sure you get a unit with sufficient wattage output, especially if planning to upgrade. Particularly on the mid-high PC side where 850W+ is becoming more common, as well as the higher-power amplifier side.

I once swore by the APC brand and hesitated to save a few bucks to go the route of an alternate brand. I bought this model (and brand) based on some reviews and some of the features and so far I'm quite happy with the purchase. Here is what all I have plugged into mine: Backup Side (90-130 watt average load): HP TouchSmart IQ846 PC 2 Western Digital 3 TB external hard drives NetGear 7550 DSL Modem/Router Cisco E4200 Router Surge Side: Sony 40" Google TV Sony Blu-Ray player 2 Sony external DVD burners DirecTV HD DVR Other: DSL raw line (before being split to phone and modem) USB to PC (for controlling the UPS) ** I saw no need to plug my satellite line in since the power source is coming from a transformer that's protected. OK, back to the review... Features I'm Most Impressed With: 10 Outlets: I have a lot of electronics conglomerated into one region and those extra outlets sure come in handy. Rather than having to buy two units, I could plug my entertainment center into the surge side and my computer system into the backup side. Now I only need one unit (in this room anyway). The only con to this is that with the unit is on the small side. The outlets are grouped fairly close so you'll need to purchase extensions if you have any plugs with bulky ends on them. Line interactive, AVR and GreenPower: I could give you a technical explanation but simply put, this is the piece of mind in knowing that your electronics are truly safe and will last a long time without the worry of a high electric bill from a constantly charging battery. I can't tell you how many times I've heard horror stories of people's electronics being short circuited due to surges. We have very dirty power in our neighborhood. When I dim the lights on a rainy night I can watch the lights flicker slightly. In the two days since I bought this unit, it already had a "moment" when it had to kick in to correct the power. It didn't trip the alarm, but it clicked and the display came on momentarily. I just smiled knowing all was well. Quiet: I had an older APC that went the way of the dinosaurs some time ago, and it hummed quite loudly. Someone suggested it was the fan, but it sounded more like an electrical hum. It was quite annoying. This unit is completely silent. Peace. Intelligent LCD: This unit has a very nicely put together LCD. It's very informative and easy to use. You can see nearly every aspect of your UPS status and power consumption measured in a slew of different ways via the display. I prefer to keep mine on the floor, but the entire unit is very sleek and would look nice even on your desktop if you chose. Just keep in mind the display turns off after a few minutes Sinewave: This is a plus, but most of the electronics that you probably use would not be affected by this. If they were affected, they would only be affected when the power goes out and the battery kicks in. Although you wouldn't have battery backup to that device, it would still be protected. This feature just ensures broader compatibility with probably anything you plug into it. Replaceable Battery: My last APC unit didn't have a replaceable battery and it was rather costly having to buy a whole new unit every few years or so. Most newer UPS units have replaceable batteries now, so that's not a concern. Features I'm Least Impressed With: Battery Run-time: I've read some other reviews mentioning the units inflated battery run-time, and they seem true. The interface on my PC (at an average of about 100 watts usage) tells me my battery run-time should be about 40 minutes. Problem is when I kicked it over in test mode I lost 7% battery in the course of about 2 minutes. I have yet to test it all the way***, but based on the drop I saw right off the bat, I'm quite skeptic about how long I'd actually have versus CyberPower estimates. I know run-time doesn't scale linearly based on watt usage, but hopefully battery discharge doesn't scale linearly over time either. *** 04/30/2013 UPDATE: I finally experienced a long power outage. I was without power for a couple hours and I noticed that the gauge fluctuates up and down. It's fairly accurate in it's estimate, but the available time on the display fluctuated about ±5% or so. It read 58 minutes, then 55 a minute later, then 59 two minutes later, etc. You get the point. I shut down after about half an hour, and according to the gauge it had dropped to about 30 minutes, so the estimate appears to be accurate. Other Things to Note: Laser Printers: Just don't do it. I purchased an HP Color LaserJet Pro 400 and although the current draw seems to have decreased over the years, you still should never plug one into a UPS. Plug it into another outlet, preferably one on another circuit. This device can handle the surge on the line, but it's best if you can just use another circuit altogether. Most printers are wireless now anyway, so you can place them almost anywhere. Change-over Time: Although I've heard others mention this is a problem, I've not noticed any flicker or issues when it switches to battery on my system. I guess it depends on how sensitive your equipment is to momentary power loss. *** *** 04/30/2013 UPDATE: I've had the unit change-over twice now due to power outage and not once did I lose power on any of my equipment. End Notes: So far I'm very impressed with this unit. Of course my basis of comparison is a decades old UPS, but nevertheless this unit seems solid and I can find peace in knowing my electronics are well protected (possibly overprotected) once again and it didn't cost me the farm. *** 04/26/2013 UPDATE: I loved it so well I bought another one! It was the CP850PFCLCD model. I use it to protect all of the equipment in my home theater.

Had this for a few months now and it's already saved me multiple headaches and concerns. I run a fairly high end rig (9800x3d + 5080 (undervolted) ) and have 1 of my 2 monitors, my tower, router, and modem plugged into the UPS. At full load my PC pushes the UPS to around 80% of it's capacity, but my PC never operates at full load. While gaming it sits at a comfortable 50-55%. The entire purpose of buying this UPS was to give me time to shut down my PC if there was a power outage, which it gives several minutes to do so and checks that box. And to also take over and protect my PC from momentary power drops/spikes which have become more frequent in my area over the past year. In the time that I've owned this UPS it's done that at least a half dozen times; I'd have a power drop for a moment, everything would flicker, but my PC stayed powered on and running like absolutely nothing happened. UPS does it's job perfectly and kicks in fast and then returns to it's normal state as soon as power from the wall is normal again. The software gives a report of what happened, what time, how long, etc. It's wonderful feeling that my PC is protected. It's not loud. It's not too large. It'd be neat if the power outlets were turned so that it was easier to plug multiple things in but it provides exactly enough for what it's size and output was designed for. It's also nice that the UPS will shut down my PC through the software so even if I'm away from home and my PC is on when the power goes out, the UPS will give it a minute and then safely shut it down. I've tested this and it works flawlessly. 10/10 buy. Would buy again.

Llevo dos días con él, pero puedo adelantar que es un equipo excelente. La configuración es sencilla y la información por primera vez sumamente útil. De acuerdo a la carga y consumo te hace un aproximado de cuánto tiempo tienes respaldo, el voltaje entrante, saliente, consumo, realmente me sorprendió, algo muy bueno es que puedes apagar el molesto pitido cuando entra en acción. Algo mejor para mí: Es increíblemente silencioso y la pantalla se apaga, no está prendida todo el tiempo, lo cual agradezco. Para una Mac Studio y su fuente de poder, se requiere la onda senoidal pura para evitar estresar el equipo y un UPS fue lo que me recomendaron quienes saben de esto. Mi No-Break va a alimentar el módem, así que nada se ha perdido. En mi caso corresponde con el modelo anunciado, fue vendido y enviado por Amazon México.

I have been buying CyberPower products for years because they are affordable and because you get a lot of premium features even in some of their least expensive units. The CP1000PFCLCD model here is just that. Very affordable with premium features like auto-voltage regulation and simulated sinewave so that it takes care of even the most delicate of electronics. A lot of people don't know that utility power coming out of their wall is not only dirty (full of noise) but also suffers from voltage spikes and sags quite regularly. All of these issues cause a lot of stress on modern day electronics. Not only does this allow you to safely shutdown your equipment during a power outage but it also safeguards your electronics from the poor quality power problems like voltage spikes, noise, voltage sags and surges as well. The cost of a unit like this one with these premium features will more than pay for itself by extending the life of your electronics like computers, switches, modems, routers, gaming systems and anything else found in a modern day home or small home/office or business. These advanced power quality correcting power back-up systems are just a must have today and it's why I have so many of them all over my home protecting all my sensitive electronic equipment. I'm happy to report that I have had 0 hardware failures due to power issues over the decades because of these CyberPower UPS units protecting everything in my home and small business. I've even noticed that the quality of these CyberPower units last forever. My oldest one is 15 years old and still going strong. The batteries have all lasted at least 8 years with the longest battery lasting 10 years! I've never had any batteries or UPS last this long from other brands like APC etc. Honestly I can't say enough good things. If you care about your electronics and you want the absolute best protection then get a CyberPower UPS with Auto voltage regulation like this one. You won't be sorry. I'm haven't been!

Has been perfect since I got it and hooked it up; had several brief power outages, and worked as intended. This is only so you have time to shut your electronics down; NOT to keep using them when the power goes out. They tell you in the instruction manual; but I've had family repeatedly ask if it will run their electronics when the power goes out.

Tenia miedo de que la degradación de la batería fuera muy prematura, de momento, esta funcionando al 100% después de casi 1 año, además, te da un infarto, cuando te das cuenta cuantos bajones de luz hay en tu red eléctrica, sobre todo si ya sabias que era inestable. Esto salva la vida útil de tus aparatos eléctricos.

Bought this solely for my NAS protection and it has worked very well automatically shutting down it down during power failures. Going to purchase the larger capacity unit for my AV rack.
