Customer Ratings & Reviews

If you buy your phone service through your cable vendor, your phone doesn't work when the power goes off. This APC backup is lower cost than the optional battery for your cable vendor's internet box, plus you can backup your wireless phone at the same time, plus you can use the surge protector outlets for other electronics close by. Pretty much a no-brainer to choose APC.

Purchased is for my Modem and network switch. Really happy with the performance.

My daughter works from home using the internet for data and phone contacts. We were having problems with electrical flash off then on again. This resulted in the router needing to go through it's reset procedure. The PC continued uninterrupted. Now we are using the APC - Back-ups 450va Battery Back-up System and we have had no further interruptions. A really great and solid, quiet product..

Just bought it……,so far it powers up & seems to work…..,will know more as times goes on….

This UPS was very handy to have when we lost power.

Perfect for our computer. It keeps all the wires in one place

Got an amazing deal for this last year and so far this battery has been operating great for the last year. Had a short power outage where I tested it and found no issues, The size is also extremely convenient to move around. Though beware the battery will probably only power your routers and modems, but don't expect it to power a PC or laptop for very long.

Compact size, simple controls, this UPS works fine for my needs.

Small, ideal for a small office.After a few power outages has worked flawlessly.

i purchased this for a client. Several years ago, some of my clients got burned because i didn't protect their PCs with UPSes. A storm came through and fried several computers. So now I require a UPS for every PC/laptop before I will agree to service them. Otherwise, i will not warranty my work. My clients have all been much happier since. APC is the best in my opinion!

Very nice Surge Protector and Battery Back-up. It's well-built and has a nice appearance

The new design is sleek and small factor you can place anywhere

Wish it had a voltage display like my old UPS. Other than it does what I need it to do.

I am quite pleased with the product. I get periodic power outages in my neighborhood. Although the outages are often short, they would often cause my modem to shut down and I would be required to reset the modem when the power was restored. Now this no longer happens. It is really easy to install and use.

Was easy to install and instructions were good.item priced well0

I bought this battery backup to use with my home alarm central hub and indoor camera from Simplisafe. Easy to use as you just plug it and the battery charged when necessary. Last week we had a power outage lasting close to an hour and the battery backup took over and kept the charge until power was restored. Satisfied with my purchase.

Good value. Fits in small spaces, inexpensive and does the job.

Reliable and safe to keep your electronics safe. Easy to setup.

This is my fourth APC battery back-up. This unit is compact, and the price was $40, on sale. I still have extra sockets, as I also use separate surge protectors for non-critical or hi-current peripherals, such as the laser printer. Battery is non-replaceable in this unit, but batteries haven't been cheap, and the BU units do fail after a few years of regular use.

reliable brand, not just good for backup power but really their best attribute is voltage stabilizing during brownouts and other fluctuations that can harm sensitive electronics. for very low wattage consumption devices this model can up to about 2 hours, but typical uses would make 5 to 15 minutes more likely for most users.
