In Battery Backup (UPS)

Love that this UPS is Linux friendly and performs as advertised.

The only time I've heard it is when it recharged the battery, or when I had a power loss for a few mins. the size is manageable due to its stand up type frame, compared to a square box. this easily fits up against the edge of the desk. No smell. software doesn't put any lag on my system. It shows your total power consumption. It's a big enough battery to allow me to properly shut down my pc with plenty of time to spare. Running a 27in rog G Sync monitor, GTX 1080 ti, 2 x MVNe drives,4 x SSD drives, 4x HDD drives and a custom loop EK Revo D5 pump, 3 x 120mm Valdor fans,2 x 140mm corsair RGB fans, 1x 120mm corsair RGB fan, 4x RGB corsair lighting strips

Price, Quiet Operation compared with the APC I replaced. I have used APC for years but their pure sine wave unit was so loud that it could not be used in our studio.

The product is improved from my prior model without much difference in price. I like that the box is just a little bit smaller and better ventilated.

Low budget, inexpensive, effective UPS. Integrates nicely with software for Windows-based PC's

Enough power to keep my new gaming rig and 23" monitor running for 4-6 minutes during an outage. Handy display shows the estimated time remaining or other info about the power being drawn. 5 battery-backed outlets are enough for all of my important components, and the other 4 power my peripherals like the speakers. User-replaceable battery is convenient, no need to buy a complete unit in the future. The unit is small and easy to put out of sight.

Easy setup Clean looking Easy management

Front panel light is adjustable and you can easily mute it when power does go off from a front panel button.

Ease of setup Available capabilities

interfaces with NUT on NAS4Free server perfectly

- Does what it does and does it well

Pros: * form factor allows under table mounting of UPS with great access to outlets and on/off switch * the CPS USB controls available via USB interface works with many devices out of the box without additional software * wide variety of Windows/MacOS/Linux hosts supported, most commercial NAS devices (QNAP, Synology), even a Raspberry Pi 3 or 4!

- Easy to setup and use. - software is handy for viewing status. - durable. I purchased mine on May 25th 2011 and its been in use 24/7 for over 5 yrs.

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.

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.

Simple battery connection and change out, no need to use screws and dis assemble the unit like other brands. I have had these ware out over many many years but they still last the longest and easy to swap out old batteries is a must for me.

The size is great, not too big.

Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it!
