    For the $200 price point you can't ask for too many more features. The on-device display is surprisingly comprehensive and the back-up power advertised is really close to my actual testing. This is my second one. My first is 2 years older and still holds a charge as good as it did on day one. My only down is the control PC software. It is very underwhelming, and lacking in any features other than basic, basic stats. Overall, A+ Spend the extra to get something powerful and worth it.

    After having this Backup for a yr now. I can confidently say this thing is a life saver. More than two dozen times my power has surged or failed and this Backup has continued to power the following: 1. 43 in 4k Tv 2. Modem + Router 3. High end PC 4. Lamp 5. Smaller Monitor 6. 43 in Sony Bravia 4k TV 7. XBSX 8. PS5 All while having 90+ min to shut everything down. or wait to see if the power comes back on quickly. The Power surge protection is truly important. Having a sudden Surge can disrupt components, hardware and fry systems. For anyone with an older home, poor wiring in the home or just wanting to protect thier equipment this is an absolute must have. Also recommend the smaller Batt Backup that looks like a surge protector. That one works extremely well. For smaller things like lamps, Clocks, or other things you want to stay on during an outage.

    This product has already saved my new PC several times over the last few outages. It makes a noise to let you know that the power is out and that back up power has been activated. It was real easy to set up. Plug it in and plug you pc and monitor into the correct plugs marked for power during an outage

    Replacement battery backup system for my gaming PC, I had a UPS 1200 for almost 20 years before it would no longer charge the batteries. This one does much more (the front USB is so useful for keeping my headset charged!) and shows a lot of info on the screen. Definitely an upgrade, and a good priced one.

    Ideal for LAN/AV Backup

    I purchased this unit to compliment the GX1500U that I use in my electronics closet. This unit is simulated sine wave (the GX1500U is true sine wave). It is ideal for keeping the power on to all of the wall warts that keep the network up and running. I have a Generac whole-house generator so power outages never last more than 15 seconds. The CyberPower units ensure that the theater components and the router/switch/LAN devices never see an interruption. I've had no issues with these units running off of my generator. YMMV.

    I have only had it for two days and was charged for 48 hours. I need it to keep my wifi and cameras online during short outages. I bought this one because it has Ethernet protection for my modem too. Will come back with a follow-up review in ninety days and then a year.

    It was performing perfectly as I was expecting it to perform when the other day the flicking of my screen on my laptop returned at headache levels that I shutdown my laptop and was considering returning the item deciding that it wasn't going to be the kind of voltage or power regulation that was what I thought to be causing the problem. I'm still on the fence on pulling the plug on this device and returning it to whence it came from, that place being Best Buy, because I am currently trying the software for the CyberPower 1500 AVR LX1500GU3. Which must be downloaded from Cy erPower website as it has numerous settings which lets the user adjust the frequency and sensitivity when and how often the Automatic Voltage Regulation and Sinewave output as well as what criteria are used to begin using battery power as opposed to AC is used when the voltage rises to..., or drops below a certain level causing intervention by the batter. Plus, other settings which are more than I wish to go on about. Not sure if I would recommend yet but I'll say, "yes," for now.. .

    The power supply is great plug and play however when it turns on it starts beeping. Which is great so you know when it switched on however, little complicated to turn it off so make sure you keep the manual!

    I received it today in a beat up cardboard box with no packaging, loose in the box with only a plastic bag for protection. This was an open box purchase that was supposedly in excellent condition. The case is scratched and cracked. This will be going back.
