    This was a replacement of older similar product that we liked. Most people forget this important item but any computer that is a main one you want to protect, let alone protect your hard drive data if there is a power surge/outage or storm, you want to have something like this!

    I enojoy the peace of mind that I have knowing that the cyberpower battery back up allows me to have time to save any data that I might be working on as well as to be able to shut the computer system down appropriately. I highly recommend that everyone should have some form of a batter-back-up system for their computer.

    This unit works well on iMac computers with no servers needed. Just plug it in, hook up USB and set up in control panel.

    This is a great backup for computer and my monitor and power surge protector for other electronic equipment I have! Now this not going to last for hours but will give you time to safely shut down your equipment or program it to put computer in safe mode!! Plus I love the price and how easy it is to use and monitor it's self!!!

    CyberPower Battery Backup Products came along at the right time! My APC products weren't lasting. About a year on the batteries and even the electronics began failing. Been using CyberPower units (about 10 of them at any given time) for at least 4 years now and only now did one battery finally die of old age. A world of difference!!!

    I purchased this to provide continuous power to my U-Verse router/modem. This ensures that I can still use a wired telephone even during power outages. Further, since I no longer lose power to the U-Verse system, unscheduled reboots due to power outages are a thing of the past.

    Works well as my power was fluctuating a couple of days after I purchased the backup power supply. Does not automatically shut down equipment as some more sophisticated models do.

    I bought this because I used to have Tripp Lite LCD1000 years ago and needed a new UPS. I have a desktop, monitor, printer, and speakers on it now, power went out the other day and system stayed on perfectly and could have stayed on for about 15 minutes according to the software, but definitely long enough to take action.

    I was looking for an inexpensive way to keep my modem and router safe when our electricity goes out and then comes back within a minute or two. I use my laptop at home so it is on a battery and this back up power unit works great. The power has gone out 3 times since i bought it and it works like a champ. Good purchase.
