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 use this product to keep my switches protected. I wouldn't recommend it for a use requiring heavy load, but if you have a few low power devices that you would like to be surge and battery protected, this is a great solution and it come with a reasonable price tag.

    Living in the country power outages are the norm. This battery back up has worked out well to give us time to properly shut down our sensitive electronics OR charge them when they are low to make sure we can always contact someone if needed!

    Power occasionally goes out where I live so I have my internet router and modem plugged into this. This will keep the peace in the house if we have to go without power for a few hours.....at least the phones and tablets will still work.

    I purchased this to use in our store. We move our cash register to different areas and didn't want to keep re-booting everything. This gives me plenty of battery time for this as well as for power outages. Safer on my point of sale equipment as well.

    I purchased this specifically to power two LED flood lights and two garage door openers. It is now mounted to a solid beam in the roof of the garage. In the event of a power outtage, we can still open (or close) a garage door, and we still have light.

    Due to severe weather and power outages my previous APC UPS died after 5 years. After a quick trip to best buy I came across the CyberPower - 450VA Battery Back-Up System. I had enough power to drive my laptop and computer and provide protection.

    Purchased this battery back-up for my power recliner in case of power outages. It worked great last week when a storm caused a power outage. I was able to lower the recliner and get up without any problem thanks to the battery backup.

    Love these backups. Use them for TVs and Apple TV. Watch TV during brief power outages. It also protects against surge when power returns. Also good to recharge phones during extended power outages, like hurricanes. Versatile device.
