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.

This summary was generated by AI based on customer reviews.

    Good for Small office but not when connecting many heavy electronics all in one, decided I needed to upgrade with All in One Printer, 2 computers, and so forth

    I'm using this to keep the filter running on my aquarium during a power outage. I've tested it few times and get excellent runtime out of it.

    We purchased this as a back up battery for U-Verse phone service. It is easy to set up and so far have not needed a backup battery yet. It will be there for when the power goes off.

    Purchased this UPS for use on my desktop computer and have virtually eliminated all accidental shutdowns due to power fluctuations.

    If you lose power this is what you want. It has a surge protector built in. Plus it what plug in burns up due to a power surge it has an insurance policy.

    Be sure to watch your voltage because if you draw too much power and alarm is triggered that cannot be silenced. You'll definitely need a bigger one for a gaming computer.

    I bought it for my cable modem. The old UPS finally gave up the ghost. This would have been a little more convenient if the cord was a couple feet longer like the old one.

    Cheap and does what it says it will. Full load runtime on battery is only 2 minutes though but that should be plenty of time to shut your equipment down.

    Excellent product. Everyone should have one if you have any computer so if the power goes out. You have time to save your work and protect your device

    I purchased this so our parents would still have phone service if the power goes out. Only complaint is that I wish it had more plugs that were on the backup side.

    This was for a low demand use so my electronics would not loose memorized settings during frequent power interruptions and it works just fine for that.

    I bought this to replace the same brand of battery back-up that I have had for over 8 years. So, far no problems, and I'm hoping to keep it that way.

    Bought online and could not find anywhere on the website how long unit lasted on battery power. Turns out it's only about an hour which was a little disappointing.

    I am using this surge protector on our TV, TiVo and other components attached. We haven’t lost power yet to review how it works, but so far so good!
