This backup still works, which says a lot for the way it arrived. FedEx gave us a tracking number and delivery date 2 days after the order. On the delivery date my office received tracking notice that the item was delivered. It wasn't. The following day I received FedEx notice of delivery for that day and every business day there after for the next week. It never arrived. After contacting Sam's 2 weeks after the order date the rep. stated it would arrive that day. It did, but it was not my office's "Normal" FedEx delivery driver. This driver left the package in a corner and didn't notify the office manager of the package arrival, yet the tracking said my office signed for the package. The box it was shipped in was destroyed and retaped in all the corners. All the inner air bag protective packing was destroyed and the manufacturers box was bashed in. Basically the driver dropped and ran. The package looked like it was part of a World Cup soccer match that went badly. Time to change shippers Sam's Club.

This is a good value and works as advertised. They are great for a home office. I also use one in theliving room for my home theater, it works great for that and gives you a chance to shut everything down if the power goes out and keeps the power even if there is a surge or brownout.

This battery backup with surge protection is very informative about the incoming power, along with its output power. The unit is well built with quality material and is easy to check its status. I highly recommend it.

I bought three of these at Sam's Club. All three died with Error Code 21. CyberPower replaced two under warranty, but it can cost half the price of a new unit to ship back to them at your expense. A third unit died, and CyberPower initially refused to replace under warranty because I had plugged a laser printer into the Surge-Only outlets, a very dubious cop-out, but they eventually agreed to replace the third unit too. Two of the replacements have died with E21 errors. The third replacement unit has not yet been unpacked, but I expect it won't last. All six units are less than two years from original purchase date. The problem appears to be that the CyberPower motherboard cannot withstand surges from the Georgia Power Company. The surge hits and the unit dies with E21 -- even when you don't have much attached to it, and nothing plugged into the Surge Only outlets. Once you get an E21, if the unit is unplugged from the wall, power goes out, there's no backup. Your computer just abruptly turns off and you lose data. These CyberPower units have a defective design that cannot withstand an electrical surge. It becomes, basically, a non-surge power strip.

Got the product home to replace a failed unit from another brand. Easy to set up, backing up a computer, monitor, and modem. Quiet operation. It covered well for storm power interruptions the next day.

Seems to do a good job. So far so good. Using one for my office and one for my FIL electric lift chair because where he lives he has a lot of power outages.

Output voltage is about 90volts. I have tried contacting the manufacturer about the problem but its impossible to get a person on the phone. Also, the front USB-A/USB-C ports don't work. Never have. It wasn't until after the latest power outage that I went to investigate why the fan I have attached to it, sounded slow. Turns out it's always only output 90ish volts (measured on a multimeter).

overloads at 143 watts, bought two of these for small backups, had no power to backup anything and just had a hurricane, so I had to go out in 75 mph wind to connect my generator so I am not happy but refraining from using the language I used when this product failed!!!

I purchased the cyber power 4 months ago, and it would not hold a charge. I contacted the Cyber Power customer service and spoke to the help desk. They determined that because I have a surge protector plugged into the battery surge outlet, they voided all warranty. They said there is clearly a battery issue, but there is nothing they can do for me. I asked how I was supposed to know this, and I was told it is in the manual under warranty. The manual states to go to their website to review terms. If you go to their site, it says to refer to the manual. Beware, this is a waste of money, and the company will not stand behind their product!

I bought this UPS unit because for the same price, other units in different stores only offered half the capacity. However, it has the same problem that other units have, the plug spaces were designed for connectors that are not transformers. This limits the amount of electronic equipment that can be plugged in. It is also heavy, but manageable. I use it to protect my entertainment equipment (TV, cable, DVD, soundbar, etc). The included USB A and C ports are quite useful.
