Customers regard the Back-UPS Connect 450VA highly, praising its long battery life, strong performance, and ease of use. Many appreciate its compact size and reasonable price, while some wish for more space between the outlets and the inclusion of a USB port. The surge protection capabilities are also frequently highlighted as a positive feature. A few users noted some noise during operation.

    I bought this in conjunction with another problem. So far so good. Worth the buy. Nothing special of note to say. If you need it, you need it. Great value.

    Living in Florida seems to bring a lot of power surges. The APC backup stops the gateway from rebooting all the time and gives us the chance to shut things down if we lose power.

    It is not a product that solves everything, but it is something that will work for you, if you do not have the money to spend a lot. Buy it to protect your equipment, it works very well.

    I am very satisfied with this Back up UPS. Works fine. Was able to get it before the end of the day. Ordered online in the morning and it was ready before 11 am. Picking it up was a breeze!

    I have a few of these scattered around on a few office computers and they all work great. I have a different model of this product hooked up to a server and love them all. theyre worth the money.

    Nice small footprint, the power cord is rather stiff and difficult to coil/concealed but if you’re drawing a lot of power thru this unit, it’s important. I recommend it. It’s working great for me.

    Basic UPS

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This is a very basic UPS without many perks. CONS: There are no USB ports for power, no management ports for monitoring, and the battery does not appear to be replaceable. The battery connection is a very thin cable on the bottom of the unit, unlike most other APC devices. Power output (run time) is limited. PROS: APC made it easy to disable the audible alert (beeping) when it switches to battery power. Outlets are well spaced. This UPS was reasonably priced. Warranty is three years. I am using this to maintain power for a cable modem, access point, and a small 5 port switch. Buying this product was cheaper than a replacement battery for the APC I had performing the same role. I expect the battery to just outlast the warranty period.

    Works well as a battery back up and surge protector. We haven't tested it for more than a few minutes but it's protected some high priced electronics during short power outages.

    This is an excellent short term uninterruptible power supply (UPS). I use it for my TVs and computers while I am using them. They will not power these items for more than a few minutes.

    Back ups are always good to have especially during the winter months. I short period power outage I experienced helped me shut down the electronic component that I had attached, safely.

    I needed a UPS in a smaller form factor and was pleased to find a name brand unit on Best Buy's website that met my criteria. Bonus was it happened to be on sale at the time. I'm reducing a five star product by one star due to the fact the battery is not intended to be user replaceable. I haven't opened it up, but I'll assume this is a disposable unit.

    I use my battery backup to safe guard my computer equipment, and to stop having internet outages when I have power flickers that causes my router to reset. Served my needs and have not had any router restarts.

    Using as backup for wireless routers. Plugged in and charged before connecting, then used it to walk the routers where I placed them without having to restart the router. Made setting those up way easier. Resetting a mesh network after a power outage doesn’t seem fun, so the backup should help.

    I keep the battery backup stored in my network closet where it provides backup power to my modem, router, cloud drive should I lose power. Highly recommend for basic protection and if data loss is a concern.

    This is our second one of these to buy. We like that we can depend on it to keep our computer running during a power outage and the surge protector has saved our computer many times During lighting storms.

    Sonos products are all amazing. This is my 2nd sub and it finalizes our whole-home wifi sound. Don't buy Bose - buy Sonos. Trust me - I'm a musician and have a very good ear. Sonos is the real deal.

    I purchased this battery backup/surge protector to replace the older unit that died on me. This model is much smaller and lighter than the old one and it has been reliable so far.

    Replaced prior UPS that needed a new battery with this device which cost me less than a new battery. Felt I would be better off with new device especially since price was less.
