I've used Cyberpower UPS for years as I live in a suburban area subject to frequent blackouts lasting from several seconds to several days. I use Cyberpower UPS to keep my TiVo functional, keep my FIOS modem / wireless router running, and keep my iMac bittorrent server running. I've never been disappointed in Cyberpower's products and the single time I needed warranty service it was rapid and complete.

My brother has multiple handicaps and uses his laptop as his primary entertainment point. Recently his area (not far from my home) has begun suffering blackouts of several minutes to several hours duration. He asked me to select an UPS to keep his DSL modem / wireless router running. Of course I turned to Amazon and selected this model from Cyberpower.

The Westell's wall wart consumes around 7 watts. When this arrived, I charged it for 8 hours then pulled the plug with a 15 watt CFL lamp on the backup outlet. An hour later the lamp was still lit and the UPS wasn't indicating pending shutdown.

As to the green claim, it stands up. I am a 56 year old tech geek and purchased the P3 International P4400 Kill A Watt Electricity Usage Monitor from Amazon back when it was introduced. I used it to measure the watts drawn while charging then in battery maintenance. This unit does consume far less power maintaining the battery as compared to the standard CPS425SL.

Some of my Cyberpower UPS are more than 7 years old and only now are needing their batteries replaced. Battery replacement is simply removing 6 or more screws from the bottom of the UPS models I own, opening it up, unplugging the old battery, then reversing the process to install the new battery. It takes less than 5 minutes from the time I unplug it from the electric outlet until it's plugged back in and ready for service. Please be sure to observe all safety precautions when replacing the battery.

I also own UPS systems by APC and recommend them also. They offer higher output with less runtime and I use them for my quad core systems.

For the more than 2 hour to multiple day outages I purchased an ETQ generator from Amazon and a Reliance Controls transfer switch. I recommend these products for extended outages.

5.0 out of 5 stars Note maximum wattage, June 10, 2010

Unit works as advertised but unlike me, pay attention to the 255 watt maximum. I glossed over that important point to my regret; I've ordered another unit with 500 watt capacity. My system quickly overloaded the 255 watts and it turned off. I have a system with quad core, multiple LCD monitors, external hard drives, etc. This unit is for basic systems with one monitor.

1.0 out of 5 stars Equipment Warranty not honored, October 2, 2010

I had a power outage during a lightening storm. When the power came back the PC that was connected to the (3 month old) Cyberpower UPS/Surge Protector stopped working. I applied for a refund for the cost of the PC, under their equipment warranty. They made me fill tons of paperwork, made me spend 40 bucks on a diagnosis from Geek Squad(who confirmed that my motherboard was fried). After all that hassle, and mailing them the old UPS back, they claimed that their UPS had functioned fine, and refused to pay me anything. The way the refund process is setup, they can pretty deny anyone a refund. Not only does their equipment not handle a lightening surge, their equipment warranty is not worth anything.
