Bought one of these for my Synology NAS so that it handles the odd brown-out and safely shuts down during a power outage. The NAS automatically detects the UPS via the supplied USB cable, barely any configuration needed. When power gets low the NAS shuts down and automatically fires back up when power is restored.

Works as advertised. Despite what is stated in another review, this UPS works flawlessly in linux, just not with the companies official software (at least not on my system). You must use NUT. Monitoring and shutdown functions fine. https://blog.warbel.net/index.php/2017/09/15/configuring-powershield-ups-on-linux-and-integrating-into-zabbix/ Works as advertised.

working very well in the first 4 years, then, from last month, suddenly stopped working and the computer restarted. it had happened twice from last month. couldn't save the files. working very well in the first 4 years, then, from last month, suddenly stopped working and the computer restarted. it had happened twice from last month. couldn't save the files.

I use this to run a Unifi Switch-8 150W (connected to two downstream PoE access points), a Qotom mini-pc (J1900) running pfsense, and a QNAP TS-453U NAS. It works well, and gets me through power cuts here. It's quite compact and fits nicely onto a shelf on my rack, and has a good, bright, clear display so I can see what's going on. It shows load, voltage, and battery time remaining.

Cons are that there is only 2 plugs - one on the UPS and another surge protected. It also has a fixed, wired in power cable. This was a pain as I had everything set up to use IEC C15 (jug cord) type connectors and had to move a few things around.

On balance though it's great, and very good value.

It may be a great machine, however, I noticed that the support for Linux systems is poor.
The Linux driver software is not up to date, and wreaks havoc with Firefox. It also did not detect the UPS.

On Windows7 , the UPS works fine. However, the UPS software has limited functionality and comes with large and clunky user interfaces. It may be a great machine, however, I noticed that the support for Linux systems is poor.

I got this because I was sick to death of the internet going dead time after time, at least three or four times every week, usually right in the middle of some crucial piece of research. This power massager has prevented almost all further blackouts, with only one brief incident since installation. I had even tried calling Contact Energy over the problem, thinking the wiring in the house was suspect. Their dismissive response, with a threat of a $200 callout fee if the technician found nothing wrong, was entirely unhelpful and predictable.

Their dismissive response, with a threat of a $200 callout fee if the technician found nothing wrong, was entirely unhelpful and predictable. With this battery equipped surge protector, with an LCD panel showing input and output voltages, battery charge and power issue status, gives a very reassuring level of confidence in the safety and efficacy of my electrical equipment. And the price is way less than the Contact Energy callout fee! I was so pleased I bought two of them, one for my computer (except for the printer, do not use it for that!) and one for my TV and home theatre system. So my valuable stuff is well protected, and now functions reliably, at no continuing cost as well.

Great UPS. Works perfectly with my Synology NAS, no complex setup required. Very happy. Great UPS. Works perfectly with my Synology NAS, no complex setup required. Very happy.

Needed a new replacement UPS. This one is a perfect match for my Synology 4 bay NAS and hasn't missed a beat, handling every power outage from short intermittent dropouts to longer sustained ones. We are rural with power that can be erratic at times. Interfaces nicely with the NAS UPS monitoring support software. Would purchase again. Needed a new replacement UPS.

I've just set this up, powering a basic Win10 i5 desktop machine and 23" monitor.

I didn't know what to expect on the software side, but was impressed to see the UPS instantly detected and installed as a UPS HID device (after connecting the USB). Once installed, the desktop machine behaves much like a battery powered laptop. Battery and charging status is displayed in the task bar, and you can configure the power options (normal control panel settings) to provide alarms and/or hibernate etc at specified battery percentages. There is no need to install the Netguard software to get this behaviour. I'm not sure what functionality Netgua...view more I've just set this up, powering a basic Win10 i5 desktop machine and 23" monitor.

There is no need to install the Netguard software to get this behaviour. I'm not sure what functionality Netguard adds, but I suspect not needed for most home users. (None of this is unique to Dynamix, but good to see it works well with these units).

I've given it a test (flicking the power switch off) and the PC and monitor transitioned to battery without a hitch. I haven't left it to run down the battery to force PC shutdown, but given the seamless integration, I would be surprised if that doesn't work as expected.

Living in a rural location, very happy to have added some extra peace of mind.

Other notes: My i5-8xxx machine plus monitor causes the UPS to indicate 1 bar out of 4 loading on the UPS (basic office apps), so very comfortably within rating. My power down test indicates around 35 minutes of battery time at this load.

Good value for transition between power outage and startup of emergency generator without having to shut down and restart. Good value for transition between power outage and startup of emergency generator without having to shut down and restart.

An excellent product at a great price, second one bought for a second computer, An excellent product at a great price, second one bought for a second computer,

I read the Manual did everything right an run smooth then i turn my second Gamming rig on an BANG ...Kill the second Rig ..Turn out bye a friend overload ..On the Main power these unit are use on newer Wire not a old home wiring .So I lost couple power supply an a few other parts i am lucky i got spare .How ever second Rig Board damage so .Now i need to buy part from PB Tech i am returning this item learn a big lession here . Do reseach first before i go buy something ..
