    Plugged it into router/modem left it there and havent had any issue. I had to put a physical access control on the room it was in. Doesnt stop human errors! But good product, breaker pops often at home. Didnt want wifi to always be cutting out so added back up battery.

    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!

    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.

    Good quality but it seems to limit the voltage more than indicated because my computer has a performance problem when it is plugged into the voltage protector

    I can plug in 8 items at a time. Four will have battery backup. The price was reasonable. Hopefully it lasts for several years.

    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.

    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.

    I got this one on sale for $45. It's the smallest unit I have seen. It powers my computer, lamp, monitor, and my Google Mini. The few times I have lost power, the battery never let me miss a second, keeping my computer on with no hiccups. When the power does flip, this battery kicks on immediately, and emits a beeping noise to let me know that the main power is off and I should shut everything down while the battery still has juice. Love it.

    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
