    Besides ease in installing, just plug into wall, it is lighter weight than the one I replaced and takes up less space. The price was exactly as I expected and it was easy to find in your store and do a comparison of the other battery backups on display. As always, the young man at the register was cordial and friendly and answered some questions and gave me some tips on other items as well. My time in the store was just over 5 minutes!!! Great service!

    Glad i have protection for my electronics. Put my TV and sound bar on it. UPS is the way to go. It is a real bummer when your TV gets fried by lightning. No more

    I bought this to connect my router so it stays on all the time. Sometimes when it rains here the power will go out for a few seconds and I’ll lose internet connection. Now I don’t have to worry about that. I should mention this my second battery back up by this brand. I bought their 650v bb a few months ago to plug in my desktop and monitor and so far has proven effective. Overall very happy with my purchase.

    An inexpensive, simple APC that just works

    This APC's installation is trouble free. I have seen it engage several times without loss of power to my TiVo, cable modem / router, or Moca adapter. In Florida, this is very important, as our wall power drops (even briefly) every week or two. With this APC, I can see that we don't have to worry about damage to my devices or loss of service. This is especially important because my devices don't always reboot themselves properly, and if I'm gone for a long time, they'd be down. I also verified that if the APC runs completely out of battery power, it does come back on and supply power when the wall power is restored. Thank goodness! This is all I can ask for.

    When my electricity goes out, even for a couple of seconds, the Cyber Power back-up battery kicks on and stops my computer from shutting down. The screen goes black for a second, but then it comes right back on at the same page that you were viewing. I highly recommend this product for your computer back-up battery.
