" ... Barely a year old and it fails the self-test. ... "

" ... When the power flickers, this 850Va Cyberpower shuts off completely: no power, no battery, nothing. ... "
" ... After a serious power failure event and the battery is depleted the unit does not turn back on automatically when power is restored. ... "
" ... When you turn off the alarm, there is no guarantee it'll stay off even if the UPS doesn't run out of battery. ... "
" ... It does not drain the battery or lose power on the non-battery side. ... Just the battery backup side. ... "
" ... Arrived with a dead battery. ... "
" ... Less than a year and half in, the battery died. ... I've owned 3 Cyber Power UPS units and on 2, the battery died in less than a year and a half. ... "
" ... After a year the battery went bad and it kept tripping my breaker. ... "
" ... 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. ... The second I clicked that button on the software, my UPS unit shut off WITHOUT the battery (fully charged) kicking in. ... "

" ... I purchased this because I needed backup for my computer, but when I got it and hooked it up, all it did was crash my computer (4 times!). ... I called tech support only to learn that this item was not compatible with my AMD computer. ... "
" ... 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 ... Like I can really troubleshoot anything when my PC won't turn on. ... "
" ... Good UPS But when the computer is shut down it turns off the controlled outlets which are connected to my monitor as designed (which is good). ... When the computer is turned on, it goes into encryption challenge screen. ... therefore, the monitor does not turn on. ... I have to blindly enter the password. ... "
" ... Nothing connected to the batter backup works. ... "
" ... I paid a premium for the UPS, but before this I was literally using just a cheap 2 to 6 outlet adapter. ... "

" ... It would falsely detect a loss of power. ... "
" ... I bought this backup power supply because I was frequently losing power. ... "

" ... It constantly fails, even when the power does not go down. ... "
" ... Can't handle real power. ... "
" ... Power went out and after 5 min everything connected to backup had no more power. ... "
" ... This normally means it isn't getting power or something, but it was getting power. ... "

" ... Very concerned 😟 plugged this in for the first time today 😳 didn't even touch the POWER BUTTON and can hear a high pitched humming noise from this unit 😳 not happy and very concerned ... "
" ... There's a loud beeping that goes off in case of a 'power event' which makes sense for some users but I'm suspecting it doesn't make sense for many home-based users such as myself. ... So, randomly, I'll wake up to a massively loud beeping at 4am and have to scramble to turn it off in a half-awake daze. ... "
" ... It would make a high pitch sound and eventually just failed. ... "
" ... Makes a constant beep sound if I draw a little too much, then shuts off, even if it's plugged in. ... "
" ... This device also makes a high pitched whining noise frequently. ... "
" ... This solid BEEEEEEP will happen at any time, will not stop on its own, and is loud enough to wake me up from a 2nd story bedroom when the unit is in the basement. ... "

" ... You can 'disable' it via the GUI client on Windows or use the pwrstat CLI, either can be downloaded. ... As a treat, the CLI is riddled with typos and is frankly embarrassing to read. ... "
" ... There is a known software glitch in these units which many people are having which cause the UPS to randomly shut down causing power loss to your devices. ... "
" ... The email address listed in the instructions bounces as not existing, and they don't answer the phone which goes to a vm box after about 15 minutes on hold. ... I originally got this to keep my PS4 from needing a factory reset after occasional 2 second power outages happen during saving/updates. ... "

They worked for about 6 months then all the sudden a VERY minute power flicker (as in nothing shut down) they started blaring the alarm and simply shut down. ... 95% of the time this is while my kids are sleeping and the alarm doesnt stay on mute. ... I asked him multiple times how could a battery back up default to off and blair an alarm for overvoltage when everything was powered off or in standby mode? ... "
