    This battery back-up works very nicely for my computer and peripherals. If you have ever had your power go out when in the middle of a computer task you will see the value of this.

    I use these as portable batteries during Halloween or other events where i need an electrical outlet and there are none available. After i figured out how to silence the warning sound when the unit is running in battery, it became the best portable battery for lighting, sound, etc.

    I have a tremendous amount of devices to power at my desk at home and I've been using an older CyberPower unit for many years. It finally bit the dust, so I purchased this replacement, and it has enough plugs to power everything with some extra to grow into. Highly recommend, especially for the price!

    My PC was having problems with the previous UPS attached to it. I decided to try this one as it exceeded the wattage needed to run my computer. I've been highly satisfied with this product and will likely turn to CyberPower when it's time to get another one.
