After one month of use, this device is doing everything I need it to and is proving to be just as high-quality as my previous (and slightly more expensive) APC brand battery back-up device that had died after several years of use. I bought this device for both the surge protection (I live in an area with unsteady current that tends to fry electronics and appliances without using high-quality surge protectors) and for the battery backup (we also have power outages due to hurricanes and fairly short but regular power outages in general). For such a compact unit (4" x 8"), I'm impressed that it has 8 outlets (4 are surge protection only, and 4 are surge protection and battery back-up). After fully charging it, I unplugged it to test how long the battery could last, and it actually charged 3 devices (2 iPhones and an iPad) - one hour each consecutively (not simultaneously) - for over 3 hours of use total! I'm guessing it wouldn't last as long if you're running/charger larger devices/appliances, running/charging multiple devices simultaneously, etc., but I just wanted to get an idea of its capabilities. As it lists in the manual, if you don't want to hear the constant beeping when your power goes out and the battery backup system is engaged, simply press the power button twice (quickly) to disable the alarm. Fantastic price, size, and quality! Will probably order a couple more, so that I can use in different locations in my home to ensure my electronics are protected and to have the peace of mind that I'll have great back-up power when the power goes out.

This is a great product. Compact, small. Good enough to keep my network hub, modem and nas working when energy goes off. This is the second I buy. Its features are all I need. And beyond the battery-backed up outlets it also has surge protected outlets. I just don't give 5 stars because the battery replacement is a little complicated. The battery of my first one laster +2.5 years - For me, it was worth.

Works perfect. Have experienced several power outages, and this kept my computer and monitor running just fine, lots of time to save and shut down. The price was reasonable as well.

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.

It's compact and it works. Using it for battery backup of my home wireless network in case of a power outage.

Honestly this was the best $50 I've spent in years. I currently work remotely in costa rica and the power goes out ALL the time. This little baby keeps my modem and therefore the internet up and running non-stop. Its a life saver.

I purchased this battery backup for use with my modem and mesh router. There was a lightning strike on my street earlier this year where I lost power and was out of town at the time. I could not communicate with items at home until I returned. The CyberPower unit was easy to set up and customize the alarm. Most important to me was the ability to replace the battery by myself in the future. With some other competitive brands, you needed to send the unit to the manufacturer for battery replacement.

Very easy to use and bot as heavy as they used to be. It is also more compact.

It's compact. Not as heavy as the other one I had. Not too expensive.

Small but powerful. Easy to use, small enough to not to be a nuisance, great surge protection, worked great during 2-hour power outage, affordable. Very happy with purchase.

The CyberPower 450VA Battery Back-Up System is an outstanding safeguard for your electronic devices, offering reliable power protection and backup.

Highly recommended for anyone looking to enhance their power protection strategy.

I bought it near the start of winter, the "slow" season. Now, we've already had a couple of thunderstorms. Usually I shut down during a storm. Not any more. Lost power once and the computer was on. The UPS made a click (same click when you turn it on/off) but the PC's monitor never missed a beat. Also, another time, there was a minor power dim. Barely noticeable, just one fast occurrence. My cable box shut down and had to wait for that to reset but the PC kept right on running. I'll never be without a UPS ever again.

Using this in a church up front on the stage area to power a Netgear 12 port multi-gig PoE switch and a wireless router. Got it mainly for the switch because it can take 2 to 3 minutes to re-initialize from a power fail or glitch. Since we live stream services I did not want a prolonged interruption in case of a minor power issue. All the other network gear including our cameras are PoE so the Battery Backup unit keeps them all running. Size is nice and compact for a 450VA backup. Working great with no issues.

Great sturdy and reliable. Easy to use. Plug and play.

I have not needed the back up power yet. It is better to have and not need. Than to need and not have. Unit is compact and easy to use when needed.

I actually wanted a smaller unit with just 2 or 4 outlets. However, the alternatives were either incredibly complicated or too expensive. Of the reasonably priced and simple back-up systems, this is the better choice than the nearest competitor, APC. This unit fits flat and is smaller with essentially the same features. Price is better also.

Exactly what I was looking for - some outlets with battery backup and others with surge protection. Previous on lasted 12 years.

Purchased for power backup for cable box and TV. Works as expected and reasonably priced. Best Buy employee was a big help.
