APC Battery backup

I always try to purchase an APC UPS when the price point is not that much higher than its competitors. I never had any issues with my previous APC purchases, hence when I needed to replace my old one, I purchased this unit. So far, so good.

This battery backup unit causes my printer to make a high pitching dinging noise every time I use the printer. My printer never did this until it was plugged into this battery backup unit.

Great to have for added peace of mind in a power failure. Enough time to save important documents and get a little more use out a desktop computer.

Seems like our power goes out more and more often. Next time I'll at least be able to finish what I'm doing before taking the rest of the day off!

This UPS is a great performer and a great bargain. USB port for monitoring, Ethernet surge protection, great runtime, and easily replaceable battery? The choice is as easy as A.P.C.

Good device from a reputable company. Worked well out of the box. It was a replacement for an older system that the battery died on. Getting a replacement batter for these systems is costs almost as much as a new system and is a hassle to find.

Bought this to replace my dinosaur APR that fried during a huge storm (like it should do) after many years of service. Great product and value.

Works as described. Currently running netgear 7300/dst through it, so far it appears to work. Haven't tested the power continuity.

I have been using apc products for years with great success. This product works great. The spaces between the plugs are ideal.

I really like this product. It notifies me if I am pulling too much current to one area of my house, which is a good reminder of usage!

I purchased this when it was on a daily sale. It was almost as much as a replacement battery. Why not get a whole new unit.

I bought this product to provide back-up power for my computer and monitors. It has done its job admirably on at least two occasions. Bought it when the price was discounted so it was an extremely good buy at Best Buy.

Power where I live can randomly flicker or go out. I work from home so having power to at least save what I was working on is great.
