Works
So far, works well. No clue as to longevity of battery. Good value. No outages since it was put in use, so no ability to rate its functionality.

Stable UPS
I have it for about half a year now, and have absolutely zero issues with it.I hooked up my home server to it along with the router and I have zero downtime since then.Absolutely hustle -free installation, it keeps my equipment running for 15-20 minutes, which is enough for short outages.Yes, I would recommend it to a friend and I will buy more of these, if I need to.

It works as designed
I want to begin by stating my bona fides. Before retiring, I was an IT field service technician. Among other things, I dealt with UPS service and replacement in corporate and retail environments.It would appear that some reviews don’t understand the proper purpose of a UPS for home systems. It is designed to prevent your device from crashing during a power outage so that you may properly shut down the device.It is NOT INTENDED to allow you to continue operating on the device in the absence of house current. That is what a laptop will do (For a limited time.) It is NOT INTENDED to run your refrigerator, ac unit, and computer device simultaneously. All UPS devices have a load level. And will complain loudly if you exceed that capacity.So, does this device perform as indicated? YES. I run a dual display and a PC off of the battery side of the UPS. And I had a power outage not too long ago, and the UPS supported my PC for at least 20 minutes. Allowing me to perform a proper shut down of the PC.The connections on the UPS are as follows. Four battery backup AC plugs, Four surge protection only AC plugs, RJ45 (Internet cable) surge protection (Input and Output), RG58 (Cable TV cable) surge protection (Input and Output), USB communication port, USB charging port, and an LCD Display.IMHO, the RG58 and the USB communication ports are superfluous. Fewer people continue to use older style cable, and while the diagnostic data is helpful in a corporate environment, for the home user, it is unnecessary.The LCD diagnostics are good, and the LCD panel is bright. I have mine mounted against the side of my desk hutch. However, because of the location of the ports, you have to mount it vertically. If you mount it horizontally, the ports will be difficult to access.All in all, I find that this device works properly, has good (And some unnecessary) features and connections, and seems to be of quality design. BTW, my model number is PST5.

Good performing product at reasonable pricing
We go through an awful lot of UPS’s. When installing sensitive, mission critical systems for businesses the devices must stay on during short power outrages and challenging power conditions.We started using the Liebert brand a few years ago and they have performed well. Importantly, the price point is very competitive. They also use standard size replacement batteries. That is very important if you have ever had to replace a battery and discovered you need to replace the entire unit.We will generally replace a battery one or two times in the lifecycle of this class UPS. This depends upon the number of incidents we note.Good quality unit and it includes a standard USB cable to connect to your UPS service on the computer or use their handy little client software.

Now I have three
The 350 VA model is not good for a PC.The Power Assist application – which worked flawlessly for me on Windows but not on Linux, will tell you that even if the average usage is below 50%, the moment you start a demanding task (a video rendering/conversion, a Photoshop filter or a heavy game), the consumption will go through the roof. It will hit above 100% of the UPS capacity, and after a few desperate beeps, your computer – and the UPS will be shut down, no questions asked.The solution is NOT to mute the UPS speaker. That will conceal the problem, not solve it. The solution is to get a more powerful model, that will never reach 100% capacity. Then you will not hear a single beep.This device can be good for your router, NAS, maybe TV. You decide which devices you want just to protect from surges, and what you want to continue working even after a power outage. But 359va it is not good for your desktop PC – unless it’s a very humble piece of hardware, with a very low wattage CPU.On the photo: on the left side (surge only) are connected non-critical devices, such as the amplifier, or one monitor. On the right side (battery backed up). only one computer and one monitor.Interestingly, on Linux the consumption was much lower for the same tasks. The UPS never shut down. Under windows, the beeping was much more frequent and the shut down was inevitable.I had a few shut downs already, so the UPS will be upgraded to 600 VA.A year later: I’ve got two 600 VA and had to buy a third one, 850 va after I added a Nvidia GPU to my PC and started playing with local AI.I was able to launch the Power Assist app on Linux. The trick is to edit the ‘powerassist’ file. It is not an executable but a script that launches a Java application.

Installed a new whole house generator, this is a must item to have so you don’t lose internet, tv service on intermittent loss of electricity on transfer switch over.

Use it for backup of router to avoid internet loss before our back generator comes on after 5 seconds of power loss. So far worked as advertised, no complaints.

I am the first to admit that my need to “be connected” is probably worthy of an intervention. That said, most of my house relies on my Internet connection. From my doorbell to my thermostats to my outlets (just to name a few), my house is steeped in IoT.Unfortunately, I live in a pretty hostile climate, and the power goes out quite regularly. No power used to mean no Internet, but not anymore! With my new UPS, my modem, router and devices with battery backup keep doing their thing. I might actually get another one to connect to another access point in my home. It would be good if I could keep my entire network up to avoid any dead or weak spots.My only problem with all UPS devices is their size and weight. I don’t want my home to end up looking like the telecom room at my office.Anyway, if being connected matters as much to you as it does to me, I recommend this UPS. It’s easy to set up and provides enough power to keep you up and running even if the outage lasts several hours.
