In Battery Backup (UPS)

LCD Display, Easy to change battery

relatively small for a 2200VA UPS, expandable (with optional battery pack), switchable plugs through serial or USB connected dedicated host.

Being located in a remote National Park we get surges from lightning storms and fluctuation also in power drops, because the 70 mile above ground phone line is affected by wind etc . I would highly recommend this unit as it seems to even out the all of these fluctuations.

Small and compact so easily hidden amongst the HiFi.

This nice reliable unit has saved me on 3 occasions now. Super glad I bought and in fact, may buy another in the near-future.

I work in music recording/mixing studio environments and am extremely fussy about equipment that generates noise. I'm pleased to say that after several months of continuous use, this Li-Ion APC rack unit met and possibly exceeded expectations. When in ideal conditions, the unit is literally silent. No fan noise, no hum, no buzz. The only time noise has been observed is either when the unit is charging (due to a power failure) where very minimal self-noise is inevitable, or in an under-voltage condition (117V or under) where the internal circuitry activates in order to boost the output voltage. In comparison to APC's own legacy units (ie: 2U 750VA-1500VA lead acid monsters) which I have been using for over 15 years - they had frequent noticeable cooling fan noise, and could produce undesirable self-noise when approaching maximum load. And anecdotally, I have had one or two units fail over the years and drop the load.

Great looking, battery is easy to change when that day arrives, protects all my gear including my pellet stove. What I really like is it allows me to power my devices & keep my home warm (pellet stove) using a cheap generator if the power goes out (it does).

I have the base Mid-2011 21.5" iMac. I wanted to protect my investment and my files! The iMac uses an Active PFC power supply so a pure sine wave UPS is required for proper functionality. The USB connection on this unit integrates perfectly with the OSX power save panel. Connect the USB cable and a set of options for automaically shutting down the iMac while being powered by UPS become available. You can adjust to shut down after x minutes or x% of UPS power remaining. I was also concerned about the power draw, and was originally considering a larger unit - but with the iMac and one external drive connected the load is only about 20%, and the estimated battery runtime is about 40 minutes. Checked it by pulling the plug - got the notice on the iMac screen that it's now running on battery and to save your work soon. The display on the unit is very informative and it has a small form factor. For OSX compatibility, price, and performance this UPS can't be beat.

Lots of POWER! Lots of BACKUP JUICE! Reinforces/surpasses expectations, maintained confidence in reliability and build-quality of CyberPower products. Finally, can toss miniature nuclear power source and depleted uranium rods in garbage or over fence into neighbor's back yard.

***An updated after several months of usage, and a change in score to 5 stars as I've learned more about the unit. Buried in the software which is run through your web browser, is a setting to turn down the sensitivity on the incoming voltage which fixes my major con of this unit for me, the unit toggling between ac and battery constantly. *** Very straight forward to setup, the units interface is fairly intuitive to use. Provided me with roughly 30min of power for 2 computers, I7 7700K with a 1080ti, and a I9 10590XE with a 3080, a boat load of SSD drives between them, lots of peripherals and 3 monitors. No blip in the computers performance when switching between battery and ac driven power. Online web interface for real time monitoring of the unit is a nice plus, can send you email reports when issues arise with the unit. Clear instructions to position the unit in it's final resting place before you connect the battery. This style battery shouldn't be moved around once it's connected.

Short story, it works! Purchased about a year ago. Couple of weeks ago, mains power bounced up and down 4 times in 60 seconds, then went out for good for a few hours. UPS seems to have about 20 minutes of power at a 250 watt draw, or thereabouts. When UPS battery got to 50%, I had it trigger shutdown of the CPU. That all triggered very nicely, got a clean shutdown, everything worked as expected. Yay! BTW -- this is with Linux, Debian Stable, using a USB cable between CPU and computer. On the UPS, I mostly left everything at factory defaults, so my app is simple, undemanding.

Best investment Ive made to my electronics yet.

Stable, high performance rack mountable unit. Lives up to the specs. Easy to manage with provided software.

Don't own one yet, so I can't say completely, but I have been favoring the CyberPower Smart App line for our servers and networking UPS's. They have the right options at the right prices.
