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.

    Good investment for computer safety

    This UPS provides more than enough power for my granddaughter's computer. She has some electrical problems in her home and this keeps it from shutting her computer off abruptly when the breaker trips.

    Great UPS for Small applications

    This works great for providing backup power to small devices such as low-end network equipment or home routers. It doesn't have a USB port for automated PC shutdown which is why I only rated it 4 out of 5 stars. If you want that option I suggest you go with a higher-end APC model. I've also used APC products for many years and they have always been very reliable.

    Once I hooked up my computer and printer to this battery back-up, I haven't thought about it. I feel secure knowing I will have time to shut everything down should the power go out for an extended period of time.

    Really good battery backup, new design takes a lot less space than the old version and overall a good investment to keep the PC safe.

    I love these! I own several. They are great for when the electricity hiccups...or goes off. Gives me time to shut computers and stuff down without data loss.

    Perfect for surge protection and back up power in case of outage. This was highly recommended for my business and it works perfectly! I am very happy with my purchase.

    It works well as a surge protector and keeps the computer running long enough for a controlled shutdown.

    Works as one would expect. no surprises good or bad. What I like about it are the dimensions, narrower and a little taller than my prior one. Fits much more snugly up against the wall and out of the way.

    Works well for smaller systems or equipment

    This unit works well for small computers or other equipment that doesn't require a large amount of capacity. We use it for our cable/fiber modem to prevent outages when we have brown outs or brief blackouts. However, it doesn't have AVR (Automatic Voltage Regulation) so you'll have to get a higher end model if you require that feature.

    I bought this back up a month ago and it works great when I have power and when I don't. I bought one back in october last year and its 3 times heavier and two times bulkier than this product. Excellent buy!

    This product avoids the usual question of what to do with strangely shaped plugs. The orientation of the plugs accommodated all our adapters. Activating the battery portion was well-designed also--very intuitive.

    I bought this a pretty nice sale, and use it primarily for my 3d Printer. While it would last longer for a 3d Printer, it will last through a quick flicker or brown out. I also have one for my network.

    I bought this for a digital sound mixer. If the unit shuts off before the speakers...BANG! It happened recently, but the speakers survived. Next time I might not be as lucky. This is cheap insurance.

    Protect your WiFi from going out during a power outage so you can email your power company that you don't have power because a tree fell on the power lines!
