Customers are saying

Customers are positive about the 450VA Battery Back-Up System's long battery life, surge protection, and performance. Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    I had to power surge before & it worked wonders even after my daugther spill liquid in serveral outlets but I had to get another for my fireplace / tv stand I got for christmas.. and still works prefect sometimes I wish the price was a lil lower cause I also need two more for other rooms of my home. But I really love it. It doesn't trigger a power outage (my house is pretty old n electric wise my landlord isn't fixing) so that's a huuuge plus in my book.

    THIS UNIT WILL GIVE YOU TIME TO SHUT DOWN AS SOON AS POWER GOES OUT. DO NOT BUY IF YOU'RE LOOKING TO HAVE A UNIT POWER ON FOR LONG MINUTES AFTER THE POWER OUTAGE
