    This UPS is great for small electronic items. I use it for my router and modem. It will last about 15 minutes as long as there isn't a big power drain. The plugs are nicely spaced for big A/C adapters. It was lighter than normal UPS's. Make sure that the unit is charged 8 hours prior to using it. I will be getting one or two more for my house.

    This surge protector has 8 outlets and was purchased to safeguard against the many power strikes we get in northern Nevada. So far so good.

    Have had 2 power outages since I bought this product for my wired security camera system. As expected, my system continued to work uninterrupted which is what I wanted. The battery back up has the capacity to power my system up to a 12 hour power outage so I feel confident my home will remain protected even in the strongest storm.

    Haven't had to find out yet how good of a surge protector and generator this little guy is but so far I'm very happy with this purchase! The best part is this protector was only several bucks more than the next best one but this protector supposedly can maintain power for eight hours if the power goes out and stays out.
