CyberPower PR3000LCD Smart App Sinewave UPS System, 3000VA/2700W, 10 Outlets, AVR, Tower

First off — this thing is massive and heavy. This is not your average little power brick, so be prepared with space and maybe a second set of hands during setup. That said, it performs flawlessly. I bought it to protect my computer, internet, and live stream setup from power surges, and it’s already saved me. During a recent surge, it kicked in instantly — no shutdowns, no hiccups, just smooth transition and uninterrupted uptime. If you’re running critical gear, this is the backup you want. Just make sure you’re ready for its size and weight!

I purchased this unit just over a year ago, i decided a few days ago to do a live test to make sure it's all still running smoothly, and sure enough unplug the thing and my PC, NAS, router, modem, and monitors are all still running like nothing happened. I was even able to play a few multiplayer games of Starcraft 2 while i ran the battery down and still had plenty to spare!The AVR feature repeatedly makes a click throughout the day, but that's always when things like refrigerators and AC's and Dryers kick on. My house doesn't have the best wiring, it's a decade or so due for a tune-up, so I won't subtract any points on the unit for that. The fluctuations aren't bad enough to make anything plugged into the wall raw turn off, so I wish I could make the unit less sensitive to my utility than it can go by default, but it is what it is.As hinted before, this thing has a pretty monstrous battery on it, and it seems that's the main thing you're paying for over the similar VA, smaller, and much cheaper ($189-$229) models. It can run my whole setup for over 40 minutes while playing a relatively light game on an rtx 4080 super and i9-14900k, having two monitors (27" 1440p IPS + 1280x1024 LCD), a synology nas, and a router/modem all hooked up as well. If your setup is anything like or below mine, you will have a truly luxurious amount of time to stop whatever you're doing and save all your work in the event of a power outage... Then sit there and watch an episode of your favorite tv show on netflix afterwards (internet, in theory, should stay up during an outage if you have the modem on ups, if your provider also does phone service) else off your PLEX server. Point is this is an overkill amount of backup battery for most people, you should just save the money if all you need is time to save and shut down, but.... having more is nice.

I read several reviews here before dropping a large jar full of loose change on this unit. The MOST important thing to be aware of while reading the reviews here -- which Amazon is infamous for lumping together -- is that the PR1000LCD (in the U.S. as of October 2023) does NOT require a 5-15P to L6-30R adapter! My unit arrived with a NEMA 5-15 cord, ready to be plugged into a standard 15-Amp outlet to charge overnight before being put into service. This was a nice surprise, because the adapter I'd ordered at the same time was slated to arrive a week later. (Unfortunately, it's already shipped, so I'll end up returning it as soon as it hits the porch.)Regarding reviews mentioning cheap packaging: Maybe, but for me the Cyberpower box was inside a larger box. One of the Styrofoam corner protectors was cracked, but not badly. The bigger annoyance was that this 50-pound device was shipped USPS and our petite 90-pound letter carrier couldn't carry it up the front walk; I had to pick it up at the local post office. (Even the six-foot former Marine behind the counter there had to take a breath before heaving it onto the counter.) So yeah, the mentions of weight are spot on but, hey, it's full of lead... Q.E.D.Observations to date:- I like the detachable LCD panel; much nicer than having to crawl under the desk as I had to do with my previous UPS which failed during hurricane Idalia, and the status reports are gratifying: for me, 17% VA load with my server and monitor plus a couple of broadband routers attached, with an estimated hold-up time of nearly two hours, more than ample to get the generator running and stable and toggle the manual transfer switch.- I don't yet have feedback on sound levels, which some have mentioned (and which may or may not actually be in reference to this model... see previous comment Re. Amazon's infuriating policy of consolidating reviews of unrelated product. However, I've not simulated a power failure yet as my spouse and I both work from home and can't afford to lose connectivity during the week.- For the same reason, I don't yet have data on how this unit reacts to our generator: I'm a bit nervous there as Cyberpower claims a frequency tolerance of IIRC 3% and our Westinghouse only guarantees 7% max variance.- The outlets are a bit tight, but no more so than on competing products (or simple power strips). I had one "wall wart" that wouldn't fit among the other cords, but a simple "two-prong-to-three prong" adapter gave enough clearance.So far, the only slight negative regarding the actual product is that it would have been nice had Cyberpower included a blank panel to snap in when using the LCD remotely. Without one, with the LCD removed the case looks a bit "raw" and I'd prefer it to be buttoned up. I plan to design one and run it out on the 3D printer.Everyone always says, when they submit a product review before the end of the honeymoon, that they'll post a follow-up; few do. At the moment I intend to but, honestly, I probably won't. Just be aware of the "adapter not required" and save yourself some irritation!

I've had this for a bit over a month. I have a tower PC with a 1000-watt power supply, and 6 monitors. As it is, it's only using 300 watts, but this UPS would handle it all if the power supply was running at full load, with power to spare. Its estimated run time is over an hour with ~300 watts load, but I have it set up to shut the PC down after 15 minutes of lost power. That way if the lights aren't off long, the PC stays on, and it doesn't drain the batteries. It's done that a couple of times so far with no issues. It's also had to adjust for low and high line voltages during that time. Since Beryl came through, power hasn't been stable here. This unit makes it stable. I really like the removeable display that I can mount where it's easy to view, and the information I get from it. The PowerPanel software makes it easy to change settings and keeps a record of events. This is overkill for a laptop, but worth protecting a few thousand dollars worth of equipment. Be sure to read the manual to get the full benefit of all the features. I'd definitely buy another one, but I really don't need a second one yet.
