    UPS units are a must for any electronics items in your home . .I have about 5 of them in use .... and have never had an issue with brownouts, lightning strikes, etc. And when it comes to UPS .. CyberPower is top of the line .. it does the job in the background and adds confidence that your PC, TV, etc will be there working when you need it.

    I like to keep my high dollar electronics, like TV, Home entertainment system, computer---. So when my old unit for my TV battery died, I found this for only another $20 more than just a battery. It works great! I live in flicker and flash part of Florida, if you want to keep using it, protect it or replace it.

    Problem-free UPS. Just plug it in, plug in your PC/Mac and peripherals and that's it! It does come with a USB connection to your PC/Mac as well as software so that you can monitor its health and set up your power down events during a power black out. Once it's set up, you can forget about it until a power outage. Then, you'll be thankful...
