    Does exactly what it needs to do at an affordable price! I am using this for my router and modem to help protect them in power outages. For the price you aren't going to get much better and it does everything it needs to do.

    Works as advertised. Protects computers and gives us time to close and save files when power goes out.

    My two year old APC UPS battery died. I use a UPS for my desktop. I went looking for something less expensive and found this brand. It has two outlets connected to the battery and six others that are surge protected.

    I should've purchased one of these a long time ago. I has already been tested. Held power with no issues. I was able to save and exit what I was doing with no power loss to the computer I was on.

    I charged the device for a day and plugged it right in and it worked. There are separate sides for with battery backup and just surge suppression. The outlets are a decent so the larger plugs still fit.

    I made this purchase looking for a battery back up that would not break the bank but would protect our periphals from surges which happens a lot here. The battery back up system came highly recommended and has good reviews. So far we are well please and have bought 3 more.

    Works Great...but the annoying beep

    we had a power outage for about 30 minutes and worked great but why does it have to beep every 30 seconds to tell you the power is out? The APC battery pack doesn't have that annoying beep unless the batter runs low. It's good if you don't have this battery pack in a bedroom.

    Definitely a must grab item to protect any computer set up or gaming set up from brown outs and black outs. Just a week into getting a new computer set up had a surprise black out, and power dropped. I was able to safely shut down my computer with the time this gave me and I didn't lose the projects I was working on. Worth the price for what it does.

    The CyberPower-450A works perfectly and the price was perfect, it is used to power my workstation and router. It is also a good protection against damages due to power surge.

    I always buy this reliable product to prevent loss of work, during a power failure. Always works, until it dies. Great price & necessary to save work.

    Purchased this unit mainly for a small powered recliner. My wife had both hips replaced and if reclined during a power failure she could not lower the leg portion and was stuck sitting until power was restored. The chair load is only 180VA. Once charged, I plugged the chair into the Cyber Power's motor side, disconnected it from the outlet and it smoothly lowered the recliner. Perfect. I'll also add a small lamp.

    Capable protection versus often inconvenient interruptions in power. This model provides enough protection and backup power to orderly shut down a PC (along with all its peripherals) plugged into this unit. Nothing fancy or special, just the basics here.

    Great battery back-up with plenty of outlets and a nice long cord. Very happy with it, and feeling secure in knowing I'll be able to stay connected in power outages.
