    Power when you need it most

    Power when you need it most, this battery backup provides enough power during an outage to protect your sensitive electronics from a harsh shutdown, gaming systems, computers and more can no longer stand the abrupt shutdown of losing power which is equivalent to ripping the cable from the wall, providing about 20 minutes of additional power giving you time to properly care for the electronics you care for most.

    My old one died (lasted about 6 yrs) and I purchased two. One for my home office and one for business. It was easy to set up, plugged everything in, everything seems to work fine. Have already made it through a couple of lightening storms with no issues.

    Works well, expect to replace the battery within 2 years or buy another. We run them 24/7 in our environment, they don't last forever but they do what they are supposed to.

    Originally bought to replace a Cyberpower 1200 vac but since already had the 750 vac unit decided to use this for fiber modem, WIFI, antenna booster and other peripheral items. I moved the 750 vac to replace the older 1200 vac unit. Will be interesting to see how long the battery last before a replacement is needed.

    This is the first UPS I have purchased. It's definitely a great purchase and very inexpensive insurance for your PC/peripherals or TV. There is software available as an online download to monitor the battery and function. I am happy with it.
