Customers are pleased with the 650VA Battery Back-Up System, especially the battery life, overall performance, and ease of use.

A few others mentioned the unit may be a bit heavy.

    Its our summer of storms in Florida now and this year seems to be a record setting year. I get tired of resetting clocks and other device that dont have battery back up so the physical size, amps and the number of outlets on this ups was perfect. Remember, if you cant put it where you want it, whats the point?

    Use this UPS as surge protector and battery back up for a computer and screen. Using the Cyberpower software to shut off devices if power fails for longer than available battery back up. It works. No problems encountered. Also have other Cyberpower UPS doing same on surveillance system, router. Good protection.

    Got this and it has worked like a charm! There are unexpected storms here in SOFO, so this was much needed for the random outages!

    I bought this to provide backup power to my cable modem and router. With this we will always have internet available even when the power drops off. Obviously until the cable company is affected by loss of power as well. I recommend an UPS or some sort of surge protection for your large appliances as well.

    This is a great battery backup for when you need one in a hurry to cover your needs. It has all the functionality of a big battery backup in a 650 version. It has every plug option I needed for a monitor, desktop computer, printer, and light. And a great price too.

    We bought two of these (his and hers) for desktop pcs'. We have only used one so far because the old one conked out on "hers". We knew our old ones were purchased within days of each other so we would need a "his" replacement soon. The price was nice and so far we are pleased. It has only been on a few weeks so time will tell.

    Definitely works as expected. This particular brand works just as well if not better than the more recognizable name brand. The price point is much better which has encouraged me to buy a couple of more to keep around for emergencies and not have to worry about the power going down.

    I purchased two of these to keep my fish tank from going offline during power outage. Fish tank online you say? No, that isn’t a mistake. Welcome to the modern age when even my saltwater fish tank is smart and connected to the internet. Fish need YouTube too. Anyways, not much to say about this device other then it is perfect for what I needed.

    The UPC has already proven its worth during spring storm outages. Usually we only buy the APC brand but a sale on CyberPower presented an excellent opportunity to try one out. Money saving is the demand that 2020 has presented us with, thus we’ll be ordering more of this brand in an effort to save $$!

    My girlfriend works from home. She has to keep computer and internet connection live. I have this one connected to my essential internet devices - modem, router and switch. With 650VA, it should be able to keep connection alive for hours, even if power goes out for long time.

    I’ve only used this for a couple weeks and my computer hasn’t arrived yet, but it’s worked perfectly in a couple of power outages that we’ve had. I keep my iPad Pro plugged into it and it has a couple of very handy USB power plugs in it too. It’s a nice compact size with plenty of plugs for my uses.

    I live in rural area and it seems we have more than our share of power fails. Nearly every time this happened I would loose the Excel document updates. Hours of work vanished. Now with the battery back up I have been saved many times. One save paid for itself !
