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!




Nice UPS. Unlike the many datacenter-style rackmount APC UPS units I've used, this one has an informative LCD display, including information about estimated runtime on battery, volts/frequency in/out, % load and number of outage events. And unlike the LCD readouts on many gaming gadgets, this LCD display is bright enough to be readable but not so bright as to be obnoxious. I was quite surprised at how lightweight this thing was-- my wife carried it in by herself-- a far cry from the UPSes we have at work which are usually moved around by two burly men and a hand cart. I couldn't find any information about using Ubuntu with this particular APC model, but I'd had good luck with APC's stuff and Linux/OpenBSD/FreeBSD in the past (albeit with the serial cable models), so I decided to take a chance. I was expecting to at least have to install something via apt, but no-- UPS event notification worked right out of the box! An icon just appeared in my notification tray (Ubuntu 11.04).

It works! I am a 3D animator running a pretty hefty system, and I live in an area that has a lot of power outages due to thunder storms. I have been able to safely shut off my system a few times now and save projects a few times now. Definitely a good buy.

Expandable, heavy duty, good interface

Same overall size as the RB1270 (which was the original battery), but slightly higher AH rating.



Well packed manufacturer packaging. Very clear multi-lingual user manual that is well worth the time reading the few pages in your chosen language. Very clear warning markers attached to UPS. Very difficult to install and use this unit without seeing the warning marker to connect the internal batteries. Silent operation; it does not have any fans on/in it that I can tell. Novel "master slave" outlet pairing. Lose power to the "master" device and the "slave" device turns off immediately. The manual tells me this feature is disabled by default, but read the user manual carefully to fully understand it's operation.

Quiet & Reliable

Great price, Doesnt hold charge for more than 10 minutes but thats more than enough time to have software shut system down.



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



Bought because the electric work in my new house is unreliable. Until I fix my house I bought this and it has saved me from so many under voltages I almost lost count. Bonus points for saving me through two thunderstorms that killed my electricity completely. I couldn't have bought it at a better time! It gives time for how long the battery will last (depends on how much current you're drawing). Kept my computer on until the electricity came back on. I feel so relieved! Plus pure sine wave is better for your sensitive electronics such as a PC than simulated sine wave. The product feels super solid and you can connect it to your PC's usb to get a system notification icon on how long the battery will last. Amazing.

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.
