    Battery was weak from the start

    I have about 3 other Cyperpower units in use. The big plus for me was always that it was fairly easy to change the battery in them. The batteries usually lasts about 2 years of constant use. Trusted this brand so much that I threw out the box and discarded the receipt even before I tested the unit. A label on the unit read that it must be charged for 8 hours before use. I charged it for 2 days before I finally plugged my computer into it. The unit would not come on and just beep. Useless. Since I threw out the box and receipt, I decided to just open it up and see what was wrong with it. Unlike my other Cyberpower models, this one uses a special kind of security crew to lock the back access panel. Could not find any kind screwdriver or bit to fit this screw. Had to brake off a small piece of plastic to remove the back panel and get access to the battery. When I put a volt meter on the battery it only read about 6 volts (should be 12v). So this battery was bad from the start. Turns out it is impossible to find a same capacity replacement battery (12v 5.5ah) that will fit in this unit, they are not for sale anywhere (store or online). Was able to fit in a different battery which has a slightly lesser capacity (5.1ah). At least I can use it now.

    Worst battery backup I've ever had

    Can't turn off the alarms (even though it claims you can), so have fun listening to a high pitched nonstop tone if it ever trips. Unit sometimes lets you use the control software on your PC, other times, greys everything out, but even if you do get lucky and can change the alarms to off, it doesn't care and will give you a nice alarm anyway. I guess it knows what it thinks to do better than the user telling it what to do. Backup time is really less than 2 minutes under a normal load if you only have a 20" Monitor and PC tower. Has gone off 3 times in 2 weeks in the middle of the night with a high pitch power outage tone (even though the power never went out), again, nonstop tone so you have no choice but to crawl out of bed at 3:00 stumble to get to the power supply and turn it off, then lay awake in bed for the next 2 hours wondering why. I have a voltage monitor installed on many outlets in my home & my home power has not dropped below 114v or over 122v and never varies from 53-56 Hz, so there is no reason for this to happen because it is in the specs of the device as "safe", so the only explanation I can give is this is a very an inferior product. Taking it back tomorrow and paying the extra 15 bucks for a non-generic manufactured backup power supply. Save yourself time and aggravation. Stay away from this unit. Does not work as claimed and gives no real user control. There are many better brands that are respected and verified good. Don't do like me, research all options first and don't try to save 10-20 bucks, you'll be a lot happier.

    No more frustration!

    I had been spending hours preparing our taxes, and the power went out. I was petrified that my work was lost. (Preparing taxes at year end is about the most hateful thing I do yearly.) I rebooted when the power came back, and happily, my work was not lost. Well, the power went out two more times! And I don't know if it was more frustrating that it only went out for a few seconds, or if I would have been happier if it went out for a while. ENOUGH of this nonsense! I researched UPS, using my most trusted sites for this - the "name brand" PC sites. They highly recommended Cyber Power over APC, and this model fit my needs at my price point. I don't need hours of power, I just need something to smooth out the glitches so that if the power waivers for a little bit, I'm not stuck with a black screen. So, at its size, power, and number of outlets for the price, I'm very happy. Also, it comes with software you can download that tells you the status of the unit. I believe that some people criticized the alarm feature, that they couldn't turn it off, but it can be controlled from the software. Yes, ok, after 30+ years of computing, what took me so long????

    Initially, i just got a regular surge protector for my new IMac 5K. For an extra $35, i brought the surge protector back and exchanged it for the battery backup which isn't even the cheapest model they have. Works great. Don't have to worry about a power outage, surge, brownout or anything messing up my computer in the electricity sense. It even integrates with my IMac that it realizes when theres no power and will turn itself off as i set it to. Integrates with Apple OS X so that i can set it to turn itself off if I'm not home and i dont have to worry about physically being there to manually shut my computer down. Its pretty much fully automated, as long as you go into system preferences>energy saver and set it from there. No 3rd party software to install, which is great since its literally integrated into my mac's operating system. this is a can't go wrong item. For a relatively cheap amount of money, not only do i have surge protection but i have a battery that will keep my computer going and possibly keep it from being damaged by a black or brown-out. Love the integration with apple's operating system.

    Seems like a great UPS for my need

    I have 2 gaming pcs that I hooked these up to. Previously I had 2 good surge protectors connected to them but felt i should take it a step further considering how much money I have invested in my pcs. I also happen to live in an apartment complex that has flaky power. This morning the power went off for a few seconds and then came back on again. Luckily, one of my pcs was powered off and the other one was in sleep mode. The price was good, reviews good, and these ups's were very easy to setup. I downloaded the PowerPanel Personal software from their website and it provides some valuable info and I was able to do a self test. I expected them to be heavier than they were. Even though there is a label indicating that these need to be charged for 8 hrs before use, it seems like mine were both fully charged. So far Im very happy with these and the peace of mind was worth the cost. Hopefully they last a while.

    Awesome UPS

    I've only had this for a few days, but so far so good! I previously purchased an APC UPS that died within weeks, so I replaced it with this one. This UPS was reasonably priced and has a USB port (which is one of the reasons I bought it). You are able to connect it to your computer to initiate a safe shutdown, as well as monitor the battery life remaining on the UPS. After letting it charge, I unplugged it from the wall to see how long it would run. I get about 20-25 minutes with the following devices running off of the battery: Mac Mini, Promise R4 Thunderbolt hard drive system, TP-Link 8 port gigabit switch, Netgear AC1900/R7000, Phillips Hue hub, a cable modem (Motorola), and the Phillips Hue LED strip. My next move is to run my Ethernet through the built in ports on the UPS. If it doesn't affect my network speeds I will keep it that way for added protection.

    using to backup my satellite tv access with DVR, 40 inch Plasma TV, and it does the job, I've had good experience with the cyberpower brand, I also use a 1000 va unit for my desktop, with a 19 in monitor and high speed internet access modem; and a 825 va is on my wife's desktop. I've had good success with cyberpower, much better than with the brand I had before a. p. c . My previous cyberpower units did great for 5 years, much longer than the other brand. My home is equipped with a 20KW backup generator, so, these units give time for the generator to get started & auto connect, this is main reason I have a ups on my sat. tv system, otherwise, if the power blinks during a program, or while dvr is recording the satellite tv has to reboot itself & do the self check . . . .

    Trouble-free Backups

    This is one of those products that is ready-to-go out of the box; there is, however, an 8 hour full-charge time required before use at maximum electrical load --- in my case, a complete computer system with dual flat-panel screens, printer, surround-sound subsystem, and scanner. The CyberPower 650 has clearly marked terminals for battery backup (6) and power surge-only (6). Compared to my old APC backup unit, CyberPower 650 is light-weight and easy to put into place and make needed connections. It is also smaller in footprint so that not as much space is required as for the APC unit. Cost effectiveness was another consideration; the CyberPower unit's cost was less than or equal to the cost of a replacement battery for the APC unit. All in all, the CyberPower 650 is a definite BUY.
