1000VA/800W Lithium UPS Battery Backup and Surge Protector, Backup Battery Power Supply with LiFePO4 Batteries(230.4 Wh), Sinewave UPS System, 10 Years Lifespan, 8 Outlets, LCD Display

So far the unit has worked flawlessly. I like that it uses lithium ion batteries instead of lead acid, so it’s compact, lighter, and should have a long maintenance free life.The aesthetics of it are much nicer than my previous UPS and I especially like that it has 10 outlets and they are ALL battery backed up, unlike my other units where only about half are battery backed up.Like the display that shows power in and power out, when the button is pressed and the ability to silence the beeping when the power goes out and the unit is running.Very satisfied so far. Bought a second unit.

Only a week into using it so far. Purchased due to SCE policy of removing power at random due to winds, and people hitting poles. Came with a good charge on it. Instructions were easy to read and understand. Purposely tested a few features and did a mock power outage, everything worked as described.Using to power the network and security system and it will run for many hours with that light load. Quiet, even with the mock power outage it ran decently quiet (beeping not counted which I turned off during the test). I like it so far.

I recently added the 800 watt version to my small server rack after using the 600 watt version for several months. Both are still in use independently on components located in different rooms and have weathered through multiple power outages. The switch over time is fast enough to not impact use of the server or workstation that it's protecting. The value is fantastic and I was specifically looking for lithium iron phosphate batteries, so the choice was easy. My only ask is to add some sort of rudimentary monitoring that could be done over usb or even a built in wifi option. During a power outage I get about 90 minutes of runtime and that keeps multiple devices up. No need to shut everything down immediately but I would like the ability to trigger a shutdown sequence on my servers once I get down to the 10 minute mark.

Working great so far! Limited features, no communication with my server to alert it to shut down, but it seems to have a long runtime and switches quickly and reliably without my equipment shutting down or power cycling.

This was the only UPS I found that produced enough output with pure sine wave power for my purpose that did not have reviews talking about randomly coming home to a room full of smoke. Despite not being familiar with the Goldenmate brand, I decided to give it a shot and I am very impressed with its performance, this unit powers my 4k gaming pc and 60in 4k tv during brownouts and power failures without issue, giving me plenty of time to save my progress and shutdown.Now I will address some of the things mentioned in the negative reviews:1. Many of the reported issues are fixed in the model with 8 outlets.2. Fan noise: the only time the fan runs on my 8 outlet model is when its on battery power and drawing 300+ watts, the noise is minimal in my opinion.3. The warning alarm: on the 8 outlet model you can silence the alarm with a quick press of the power button, as for the reviews complaining about it being too loud, I found it to be much quieter than any of the 50+ UPS units I have owned in the past.4. The smell: This is the only legitimate complaint I have seen with this unit. The smell was noticeable for the first day or so, I did not find it pleasant but could not smell it after a few minutes unless I left the room for a bit and returned. This however is common with modern electronics containing transformers so it's more or less unavoidable.The battery life and charging time is exactly as advertised (haven't seen that on a product in a long time)The only thing that I would advise is that the unit makes humming noise when the voltage regulator is correcting input power, this unit will correct the power fluctuations without switching to battery power unlike most UPS units (to a certain extent), so the tradeoff is an occasional humming instead of the usual beep other units make when they have to switch to battery power to correct incoming power. If this unit was right next to your head on a desk setup, the humming might be annoying if you have poor grid power or frequent voltage drops.

This is an amazing unit! It has everything I need except for a power fail USB signal port to automatically shut down computers. It is lightweight and compact. It has 8 power sockets on the back - all UPS protected which makes it easier to use than units with mixed types. When you connect it to the mains, it starts charging immediately. To switch the output AC on, push the front switch on for three seconds. To switch off, push for 5 seconds. This off-time is long enough that it doesn't get switched off by my roomba, as the power switch is at the bottom at the front.The unit contains an LFP or LiFEPO4 battery bank - good for three thousand full discharge cycles, so it could easily outlast its 5 year warranty - even if you have a fully draining power cut every day!Once the supply cuts out and its running on battery backup, the unit beeps every 5 seconds. While in backup, if you quickly push the front button, it stops beeping for the remainder of the current outage, but will start beeping again on the next outage. This is exactly the behavior I want. The beep is short and loud enough to hear in most rooms, but not annoying.The battery is nominally 25.6V and 9Ah at full charge, so around 220Wh total capacity.With AC output on, the unit consumes about 8-10 watts, so with no load, its run time is about:220 / (10 + output_watts), so for example, it should last 22 hours with no load (output_watts=0), and about one hour with output_watts=210. After several years it should still work, just with slightly reduced capacity, so no sudden capacity reduction with age - unlike lead acid.
