CyberPower - 450VA Battery Back-Up System - Black

Well, so far so good. I've already had a power surge and it kept all my electronics (computer, monitors, external hard drive) from frying. SO - I'm happy.

This is a great little backup that also helps stabilize the AC power. I am using it to stabilize the power going to my golf cart charger.

I purchased this backup for my desktop computer and it works perfectly. I am really happy with its performance so far. Thank you!

This device used to be big, but this particular item is really compact. That makes it convenient when you don't have a lot of space under your desk or behind the the entertainment center. Well designed to fit 8 power cords, including those power cords like the apple and Asus king, they are bing in lenght. Maybe not so convenient for those wide power connectors like those from 3.5 external disk. Price is very good, I just hope the small battery included will last long and wont run out of power before the time specified on spec. it can be laid on the floor or hang it to the wall with two screws provided with the package. The cable is very long, make it convenient to reach a power outlet that is far from your equipments.

I had long wanted battery backup for our internet so that my wife could continue an online (e.g. Zoom) meeting during a power failure without interruption and end it gracefully. I could not figure out from the info available online just how long the backup would last given the volt/amp rating of the system ( I saw estimates ranging from a few minutes to a few hours). So when this unit when on sale I bought it mainly for calibration purposes, to see how many minutes of backup a 450VA system would give me. Since our laptop batteries last nearly 2 hours, we only needed backup for the cable modem and router. The total wattage of those units was about 22.5 watts, and this system powered them for an hour and ten minutes. The box the unit came in also has a useful table on the outside, showing how long the power would last given the power consumption of what is being backed up. I could not find that info online, either in the tech specs or the summary product description on the Best Buy website. As the wattage of the devices being backed up increases, the length of time that that the backup power lasts goes down sharply. No wonder that the online estimates ranged from a few minutes to a few hours.

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!

Love this Cyber Power battery back-up system. Here in Florida my home is inclined to have the occasional power surge where electrical power switches off and one...sometimes for a second or two, sometimes even longer. With this device, having my router, landline phone, and computer/monitor all connected I never lose anything, where, without it, devices just went poof. Gone. Restart. Make sure you fully charge it for 24 hours before connecting. Definitely recommended.

We have been having short duration power outages on the order of one to five seconds so I wanted a battery backup to help protect my TV. I went on line and ordered it, drove to the store and and they brought it to me, drove home and plugged it in. The hardest part of the task was getting to the plugs behind the entertainment center.
