CyberPower - 425VA SL-Series Battery Back-Up System

Good price. Always easy to use & install. Backup has saved me.

I needed a power back-up for my phone and internet router in case of a power-out situation. So this is a very economical solution and it provides a power surge protection in addition. It's easy to install and maintenance free

Purchased this to serve as both a batter back-up in case of a power outage, but also as a surge protector. Note that if you need a Data port, this will not work. My old printer uses a data line that does not fit with this, but we have another printer that we purchased at Christmas time that we primarily use anyway.

Found this on sale to replace my 10 year old APC backup that dies for my Desktop PC. Seems to work fine but no USB connection to the PC to track charging status. At this price point it meets my needs.

3 surge and 4 surge + battery backup protection outlets give me plenty of options to protect my home computer, modem, router, printer, etc. This is my second cyber power box. The first finally died from 6 years of electrical spikes and brown outages via weather and lousy home wiring. Good price. Good product. Definitely recommended.

I have several of these cyber power battery back ups. I bought the last one because I got a new 27 inch iMac. The imac is the only thing plugged into it so it last a long time. We live in a rural area an get a lot of split second power outages. It is like some one is in the garage flipping breakers. This is really hard on my electronics. If it would just go and stay out for a few minutes it would not be so bad. The momentary disruption is brutal on all electronic equipment. With cyber power I never lose power I get a constant 115 volts with no spikes and dips. That is what you want for sensitive equipment.

After losing 2 computers in 2 years to power issues, I finally got the message! When purchasing my second computer, I also purchased the CyberPower Battery Back-up System. At the same time I also purchased a computerized embroidery machine. It was heavily advised to plug it into a back-up system to protect it. I didn't have to be told twice at that point. I've been very pleased with this battery back-up system. So far I've had 2 electric issues in which the system saved my computer and embroidery machine. Thank goodness! There are no cons to this product so far. I'll not be without one ever again.

This economical, simple device has given me peace of mind to continue working when a thunderstorm is approaching. I live in a rural area, so sometimes we lose power for no apparent reason. I wish it didn't beep so loudly when I shut it off manually. When I work at night, the beeping sometimes wakes up my husband.
