    Since we keeping losing power and afraid of power surges I ended up getting this to help protect my Wife and daughters desk top. Even when the power goes out this is also a power bank and still has power to power what ever is pluged into it. Bought 2 first and might have to go back to to more.

    I live in FL. which is the lighting capital of the world. We need protection for our electronic items and this will protect it. I will be working from home and this is necessary to protect my investments because my employer isn't paying for it. Don't wait until it's too late. Get yourself one. Make sure it has enough power for your electronics. Best Buy will help you with that.

    This cyber power battery back up is terrific. With recent blackouts of power, this type of back up is essential to have. The electric company, PG&E keeps having black outs to prevent winds blowing power lines into very dry trees and setting off sparks and thus starting added fires, it is necessary for power shut offs periodically. This battery back up is wonderful.

    Easy setup and good battery life for backing up your computer or home entertainment system. Wish the size was a bit smaller though,

    It's bulky but it has saved my work from being lost many times with the power outages we have here. Saved my equipment from frying since this takes the heat before my stuff gets it.
