Customer Ratings & Reviews

I bought this cyber power for 1 computer, and has been working perfectly find. We had blackouts and the computer didn't have any damage. My kids also connect their iPads to this device when they want to charge them, and we hadn't have any problem at all I will highly recommend it.

Great battery backup for the price, good plug room.

Needed a small UPS for my All-in-One and this one fits the bill nicely. Compact with enough umph to keep it afloat while I shut down.

Protecting a computer and data stored on it is a valuable consideration. This battery backup device eliminates one's concern during loss of electrical power and unusual surges. This device does it well.

Have not had a power outage yet but it is a fair price not to crash your system.

The quality of CyberPower - 425VA SL-Series Battery Back-Up System is excellent. The device is simple to use and performs as expected. This model is perfect for home computers or laptops (as well as my wife's computerized sewin-embroidery machine) to prevent damage and data loss due to occasional power spikes and outages. Price was excellent.

The unit works very well. No problems so far. Plenty of space for plugs, large and small. Small footprint. Pleased with purchase.

Using it to provide power to a CCTV system. Does what it is supposed to do. No problems.

I use this to back up my timer box for my yard sprinkler system. If I have a power outage, especially if I am out of town for long trips, it keeps the sprinkler system on schedule. This is especially important during the summer when we have water restrictions. This unit has plenty of juice to keep the clock on the sprinkler timer going.

This is a good UPS for low powered items. I would recommend this product

Everyone should make sure their computers have a backup battery. We've had a lot of power outages, or when the stupid power company decides to do a switch over at the station. A lot of this electronic stuff can't take that. Clocks, stoves, microwaves & especially computers!

This product does what it is intended to do. it provides a desktop computer with power protection and battery back up.

Long lasting battery life Easy to use & dependable

Both my old UPS boxes gave out so I wanted a new battery back up. Best Buy had a sale on them, and this unit fit my home small needs. I want the safety of having my power filtered and backed up in case of outage and this was a good deal.

Purchased this for my mothers house. Works great for her needs.

I like the product at the very beginning, however expect to replace shortly. These battery back-ups are important to have but they no longer live long. They tend to die and always at the worst time. My suggestion is that you buy two, one to use and one as a back-up to your back-up.

I needed a reliable backup power supply with surge protection for my main computer at home. I have a backup generator but it takes a minute for it to sense that the pole power is gone before it kicks in.I need access to my main computer 24x7 (includes accessing it remotely) and this was a reasonable solution.

Have had the product 2 months and no problems. I use it for power backup on my modem router and cloud drive.

Does the job - a little quick on the beeping in a brown out

instructions very easy to follow. liked having the extra outlets. plus the salesperson was SOOOO helpful!
