Amazon Basics UPS Battery Backup & Surge Protector 400VA/255W, 6 Outlets, Standby Uninterruptible Power Supply, for Power Outage Protection, Compact, Black

I’ve been using this Amazon Basics UPS for about a year now and it’s been great. I haven’t tested the full run time, but for the quick power outages we get at the house (usually 10–15 minutes), it’s held up without any issues. My Synology NAS stays up and running the whole time.It’s compact, doesn’t take up a lot of space, and does exactly what I bought it for. I don’t have it overloaded — just the NAS and some networking gear plugged in — and it handles everything without a hitch.You definitely get what you pay for. It’s not a huge backup system, but for keeping key gear online during short outages, it works perfectly. No complaints.

The setup was easy. Four of the sockets use the backup power, the other four don't. So I hooked up just the necessary things for backup: My PC, monitor, and router. Then I pulled the plug out of the wall. There was no interruption whatsoever - everything just kept running. It said I had 26 minutes of battery time. So I'll break that down, because so many people want a time estimate. I bought the 600va/360w version.My PC was built to be low power consumption. I estimate it consumes 150w, maximum, and much less when idle. The monitor is a medium-sized 1080p monitor. I am guessing it takes 30w. That's a blind guess. The modem, maybe 15w. So that's less than 200w, and I get 26 minutes running time. Your desktop PC probably uses a bit more power. I'm on a circuit that blows frequently, so I only need a short time while the circuit is reset. So if you're only supporting a router/modem, it should last a very long time. It is apparent to me that many of the unhappy reviewers are need a commercial-grade solution and are expecting much more power and features than this simple, inexpensive UPS has. The unit is rated at 360w. As you approach that maximum, efficiency will drop and your run time will be greatly reduced. Keep it to 200w or less, if you want good efficiency.Don't try putting a 'fridge or a microwave on this little guy. It isn't made for that. A normal laptop might get a few hours out of this. Most desktop PC's use more power than mine does, especially a fancy gaming rig or software engineer's station. If you have a mighty computer, you won't get much more than time to shut it down gracefully. A more modest computer might last 15 minutes or more. Please keep in mind these are my amateur estimates.There is software. Check under the product info on the Amazon page. I forget which tab it is under, but there's a link. Plug the supplied cable into your computer to configure the unit. Install software. It will ask for a username and password. Both are "admin" until/unless you change them. You don't have to use the software. It just lets you tinker with settings and see the battery time and load. Handy for experimenting with different loads.No complaints, it's doing just what I hoped it would do. Hope this review is helpful to some.

This UPS is great for power blips, which we get here all the time. It drove me crazy that the power would blink out for half a second, but then it would take me ten minutes to get my router back up (I work from home). This keeps the computer and router alive, which is exactly what I needed.Today was the first time the power really went out for good (I've had it for about a year) and I was disappointed that it only lasted for 50 minutes. But now that I'm checking other reviews, I see that's normal. So I'll still give it 5 stars for doing the original task beautifully.

This unit is used for wifi power and voip phone power during a power outage.Charged it up and tested it. It worked fine.The Amazon PowerMaster software had issues so I quite trying to use it and saw another review that mentioned CyberPower. Yep, that brand's units look like mine and the little manual looks the same.I downloaded the Cyberpower software and was able to monitor my unit and do a self test. All is well!

We installed a WiFi network at my place of business and were looking for multiple UPS's for each of our switches and WiFi Access Points. When looking for what device would work best I came across this Amazon Branded piece of equipment. The price was fair and I really like their, "Backed by an AmazonBasics limited 1-year warranty, including the battery; $75,000 connected equipment guarantee" - the last bullet in the description.This warranty is a joke. We had a power surge in our building and most of the UPS's worked as intended, however there was 1 that did not. All the equipment connected to it was fried after the surge and no longer works. Over $900.00 of equipment was destroyed (all of which was ordered from Amazon). I just wanted a credit I could, gift card, something! I had serial numbers and images of the equipment and everything. I immediately contacted customer support and told them that I wanted to submit an issue/claim under the "Backed by an AmazonBasics limited 1-year warranty, including the battery; $75,000 connected equipment guarantee."I had to continue to reach back out to Amazon Customer Support 3+ times, each time they told me someone would follow up with me within the next 3-5 business days on my warranty claim. I spent a total of 4-5 hours (spread out over multiple days) of my time emailing, chatting over the phone, sending pictures, chatting online and still nothing has happened. I have continually been ignored and have been given false promises of, "I will PERSONALLY call you back on (x) date to follow up with you on this issue." Then, after no phone call or follow-up, I would email them back, only to have a different person respond and tell me to call Amazon Customer Support (which means I would start from scratch and have to tell my story all over again and go through the same steps). The continuous false promises and disregard (whether intentional or not) is beyond frustrating - especially when you buy the device because of the warranty that is promised.I am a regular user of Amazon services, but I'm very disappointed with the way this situation was handled and I feel that I have wasted my time and have been ignored multiple times.Not a product I would recommend buying.
