I've had two of these UPS/battery back-up and surge protectors for over 7 years now. I used them at my business and now at my home (where I use two for one PC, monitor and cable modem). If the power goes out, I have about 10-15 minutes to safely shut down my PC. My router/cable modem should be able to function for at least another 30-45 minutes on the second UPS. This will give me time to access the internet, etc. The trick is to calculate how many watts your equipment is drawing. To translate Amp-Hours (Ah) into usable energy (Watt-Hours, Wh) or power (Watts, W), you multiply Ah by the system Voltage (V) to get Wh (Energy), then divide by time (hours) to get Watts (Power) or use Watts = Volts x Amps (Instantaneous Power). The key is knowing the battery's Voltage, as Ah only measures charge capacity, not total energy. That said, this is a very reliable product. Easy to use/connect. Bonus it includes a cable surge suppressor to protect your router/cable modem. When the power goes out, the device will beep every minute. You can mute it if you'd like on the newer versions. I'd also highly recommend you pay attention to which outlets you hook up your 'mission critical' equipment to - one side is surge protection only and the other side is surge protection AND power back-up. I've been happy with these and can not blame the manufacturer for needing to replace the sealed lead acid battery after three years. Batteries have a certain lifespan, no fault of CyberPower. I used a MightyMax battery as a direct replacement and have had no issues. Over-all, I am very satisfied with these Uninterruptable Power Supplies.

I bought this UPS for my HP Proliant ESXi server, NetGear ReadyNAS, and wireless router. The server has two L5520 processors in it, 4 sata drives, an external drive and 18 4 GB sticks of ram to give you an idea of how much equipment i have to power. I have National Grid for electric and my power goes out at least once every three weeks for a few seconds, just long enough to kill my server. I wanted something that was manageable and had enough power to last through a short outage while not draining my bank account. I gave this UPS a shot and its perfect. First off the screen on it is quite nice. It tells you everything you need to know without a computer such as how charged it is, the load its taking, how long it will last, voltage coming in and out. Its really great. The picture on Amazon is exactly the one i have. The pictures can do more justice than me telling you about it. The software that comes with it is okay, just lets you see the same info that's on the front of the UPS. Its good for a workstation but i need the UPS for a server. Instead, use the CentOS PowerPanel Business Edition server CyberPower has available. Its great!!! It's a small Linux server that controls the UPS via a web browser. It has all the automation's you can think of, like powering on and off at scheduled times, certain events and sending alerts via SMS, email and MSN messenger plus a lot more. Right now, mine is set to send a request for a graceful shutdown of all my VM's and ESXi when the powers been out for 30 seconds and when the powers been restored for five minutes, it initiates a power on sequence. Of course my ESXi also boots up critical VM's automatically so i never miss a beat now with this great UPS. It records logs as frequent as every minute and stores them for up to a year. You can even manage the individual outlets on the back through the browser. So how long does this last? With the gear i have attached to it, the gear is using about 26% of the maximum load so it can handle a lot more. I average about 16 minutes of up time with what i have attached. I've unplugged it to see and the time is pretty accurate. That's more than enough time to down a system and still charge a cell phone after in case the powers out for a long time. The battery is nice but the free management software is my biggest plus. I do not know if it works with other brands though as this is my only UPS i have access to. Update: After 4 years, it's still working like the day I got it. My power went out about a month ago and this ran my server, which currently wasn't set to automatically down my servers, for about 12 minutes. I'm only here to buy another for more servers.
