Even with no power loss, equipment that is attached to the unit, just shuts down. Bought several of these and have had problems with 2 of them. Worked for less than a year. Maybe the battery has gone bad already. Not really sure, but it doesn't compare to other Backup brands that I have purchased.
I ordered the Cyberpower CP800AVR to replace an old unit that I had good luck with. Sure it would work, but I didn't want another full unit next to my other one, so I used it on our second computer. Same problem with this unit, noise in the phone line and no speed on DSL.
After hooking everything up I had noise in my phone line and my DSL speed was terrible. I accepted this offer as I didn't want to repackage this unit and send it back. This was not the case with the CP800AVR.
The same support person could not explain this, but offered to send a separate phone line only surge protector. The support person ran me through several tests and determined the unit was bad. So I packed it up and sent it back to Amazon, who sent back another unit rather quickly.
In their infinite wisdom, Cyberpower sent me a 725SL unit. In the end I would recommend staying away from CyberPower, even the 725SL only lasted a few weeks before failing.
It is the same one on their 825AVR. The only reason why I bought a new unit was because I upgraded my computer & the new computer setup does not have a serial port therefore I could not communicate between the unit & the computer. Also the first one would announce when it was connected. I had a heck of a time installing the software; kept going through the install process. Furthermore I believe the unit I replaced not only had longer backup time; the power panel menu was nicer. It was a Power Plus Unit; this one I believe is called the personal edition. I guess it will do, as power interruptions are not that frequent so far.
I received this item in a state of disrepair. It does not work. Thank you.
Was this an oversight or do Mac users get the cable for free. Just to make sure I repackaged the item and returned it for one that claimed Mac compatability.
For people in this area a quality UPS is a must, and the CP800AVR has served me well enough since I bought it that I bought a 685VA/390W USwith Avr for my parents. I live in an area with horrendous power problems: constant brownouts, frequent blackouts, and regular power surges.
Just make sure you charge the battery for at least 16 hours before you use it for maximum performance.Last, when I first bought this item I noticed that there was no USB cable, then I noticed that there was no Mac compatibility symbol on the box. My only complaint is that I bought them both at a major electronics chain for what I later discovered to be at the top of the price range, my bad.
To make a long story short, I not only would buy this product again, for all practictical purposes, I did. In the end it turned out that Mac compatibility isn't an issue, the 800VA works fine with my Mac even without driver software; however, the UPS that claimed Mac compatibility came with a USB cable.
(I'm not using a one of the new Intel Macs either, its an older Apple iMac G5 Desktop with 17" M9843LL/A (1.8 GHz PowerPC G5, 512 MB RAM, 160 GB Hard Drive, DVD/CD-RW Drive)).
