    Using this for my flat screen tv

    I bought this unit for my tv set. I don't want the occasional short power dropouts where I live to affect the electronics in my tv. I use battery back ups for desktop computers and I consider the tv to be a computer with a really good screen. The back-up is inexpensive enough, especially compared to the price of the tv, to be worth the peace of mind.

    I bought two of these for our house. We frequently have little blips in the power that cause our computers to turn off randomly. As a video editor this can be soul crushing. I am thankful I picked these up as they have saved me from losing projects. Happy to have these. So far no problems!

    This is an excellent mini backup battery system with surge protection. Everyone should get one of these. It helps to protect your devices from a surge from black or brown outs. It also gives some back up to keep your device running.

    The battery backup permits the continuous use of the internet modem and wifi during a power outage. This is important while switching back and forth between my solar powerbank and the electric company.

    I have my NAS, router, and modem connected to this. 4 of the outlets are "protected" and the other 4 are running from the battery. These 4 battery operated are the ones that stay on backup. My only gripe about this model is that you can't turn off the outlets that are not on the backup. Since it doesn't affect performance, I'm not docking on the rating.

    This was in my 2nd round of purchasing a cyber power item (3rd product). i’ve made a complete switch for my electronics (including my bearded dragons lights) to protect them and keep power for select items. i’ve been recommending their products to other bearded dragon owners and even got my family into them. their products have saved so much of my stuff and i was able to charge my phone during a power outage.

    This is a replacement for one of my CyberPower backups that the battery had died. I chose to replace it rather than ordering a replacement to save time and the hassle. I have used CyberPower backup batteries for some time and am satisfied with their performance. I use more than one for different devices pc,tv, etc.
