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.

Along with my power supply this has been on my computer for 7 years running 24 hours a day most times. It is on the original battery still.

Works great.


Plug spacing is super efficient. UPS back-up software works. Win 10 recognized software.Had a power failure day after i installed it. Shutdown went according to plan..

Works exactly as intended. Many modern homes have an outlet on the wall for a wall mounted TV. I needed surge protection in a compact design, this worked perfectly.

- Great packaging, fast delivery.



It's a battery... it holds a charge

Charged battery and it works great. Have the essentials plugged in for those brownouts and power bumps. Makes life easier when you don't have to restart computers, modems and routers.


Keeps my UPS running

It works. Push button on/off switch. Spaces for the large adapter plugs. Not much else to say other than now I can plug in all of my computer junk to one surge protector.

-Right from the start, I noticed a decrease in noise from all that is hooked up to this bad boy (computer, fan, vacuum) -I hooked my cable and internet up also, and for once the cable came in clear, not much change in internet tho :P -I like the design, and it really isn't as big as other suppressors of it's price range

This UPS was a great solution to support networking equipment (modem, router, switch) that I installed in my basement. It has lots of outlets and the size of the unit was perfect for mounting on the network wall panel.

Slim design High quality Dust covers Flat wall plug Green led ''Protected'' Red led ''Not Grounded''

Mounts easily in short-depth racks, making it fit in nicely with network switches or audio gear. Cheap.

Lots of outlets. Long cord. Protected Switch cover, Reset switch. Does what it is supposed to do. Own about 25 of these and not one of them has failed!
