Not really sure, but it doesn't compare to other Backup brands that I have purchased. 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.
In the end I would recommend staying away from CyberPower, even the 725SL only lasted a few weeks before failing. The same support person could not explain this, but offered to send a separate phone line only surge protector. 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. This was not the case with the CP800AVR.
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 ordered the Cyberpower CP800AVR to replace an old unit that I had good luck with. The support person ran me through several tests and determined the unit was bad.
I accepted this offer as I didn't want to repackage this unit and send it back.
I guess it will do, as power interruptions are not that frequent so far. It is the same one on their 825AVR. 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. 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. I had a heck of a time installing the software; kept going through the install process. Also the first one would announce when it was connected.
It does not work. I received this item in a state of disrepair. Thank you.
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. To make a long story short, I not only would buy this product again, for all practictical purposes, I did.
(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)). Just to make sure I repackaged the item and returned it for one that claimed Mac compatability.
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. Was this an oversight or do Mac users get the cable for free.
I live in an area with horrendous power problems: constant brownouts, frequent blackouts, and regular power surges. 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.
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.
