    This UPC is just right for powering your modem and WiFi gateway during a power blip. Great peace of mind to have 90 minutes of power backup in case of a power blip or thunderstorm.

    This UPS has a very small footprint and works very well in keeping my router and TV on when I have power surges or power goes out for a while. So no more rebooting the router!

    I got this unit to handle all the external devices (2 monitors, USB 3 multi adapter, Ethernet switch) attached to my wife's laptop. We've already had 2 shorter power outages...the attached equipment continued to run no problems.

    I got tired of having to re-enter radio stations on my tuner every time the power went out for a few minutes. I have a couple of these for different stereo receivers. I also have larger UPS's for the computers and the TVs.

    This has been an invaluable buy with the electricity going off EVERY day for hours; I am so thankful for the suggestion from my Technician to purchase a really good battery back up system.

    Not a lot of time if total outage , but keeps the modem from freeking out with the momentary flickers. All attached devices work without interruption like the “ups” means. Like it is supposed to.

    Bought this because of frequent brown-outs. It keeps all systems running, no issues. Not sure how it does for the long term backup (haven't needed it yet)but for my needs works great.

    Just bought an Apple Desktop 27" with 5k Retina display, so I wanted to protect my investment because there are too many times during stormy weather that the power goes out. This item should be a necessity to protect your computers, routers, etc...
