I have my stereo components, computer, printer, TV, cable box and Bluray player hooked up to this backup system. I love the fact that you have twelve outlets to use!

Perfect for what we needed. Need to put a sticker on the top of the device to alert those who don't read the pamphlet first that laser printers and other named devices are not to be plugged into the Battery & Surge protected outlets. This warrants special attention to the consumer, in my opinion.

I have this power backup hooked up to my satellite receiver box and TV. When the power flickers everything stays on, and don't have to wait for stuff to reset.

I purchased this battery backup for several USB hard drives that I need to protest. It's compact size and the number of protected outlets make it ideal.

Great value for 850va AVR battery that is almost 1/2 the size/weight of my old Cyberpower 900 unit. Electrical sockets very easy to access. Glad I found it at BestBuy.

This unit has lots of power plugins and a good amount of battery power for the price. The next significant improvement in specs will cost you a lot more money.

Tried another brand before and it didn't last. This is my second UPS from CyberPower, they seem to be making much better devices than other brands.

I purchased this to obviously give me power to important devices after a power outage. I haven't had an outage yet, but I fully anticipate it working as expected.

I have a computer that trade stocks on the New York Stock Exchange. I like having the back up battery so I can continue to trade when the power is out

I guess buying a battery backup is kind of like buying insurance. You hope you never need it but if you do you'll be glad you have it! It was super easy to hook up.

Some people buy a UPS just for the battery back-up but for some delicate equipment a power conditioner is what is needed. This is a good price for both.

Often in Florida there are power outages, some brief and some longer. My mother-in-law is disabled and we were constantly reseting her internet and cable power to restore TV and communications. This device has worked for us and is now for my mother-in-law
