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

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.

I got several of these for my home office, to replace some older traditional style UPS units. Across the units I own, I run a NAS, several computers, monitors, network gear, WIFI PoE, etc. They handle the workload like a champ and I'm hoping the long battery life will mean this is the last time I buy a UPS or replacement batteries in a good while. Very easy to use and setup, nice readout display with status, I'm a fan. This is my first time using lithium UPS batteries. Runtime is as expected and reasonably good.

I actually love this product. I bought two works great but I wish it had a wireless way to check status. It saved me with a recent power outage with a lot of expensive equiptment and gave me plenty of time to get things offline. I just wish I could get a way to notify me if the grid power was down, check battery level, and not have to use the display that takes a few seconds before it shows anything especially when dealing with an urgent situation. I would still buy again and I wish they had a larger model. But please make a new version so I can have it linked into my home automation!

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.

I got this because my Xbox Series X kept flipping my breaker (this fixed it). After 30+ hours of lost game play, I did bunch of research and landed on this one due to its large battery, high output (VA), and pure sine wave (see bottom for sine wave details). After plugging in my entire home theater (85” TV, sound bar, Xbox, Nintendo, AppleTV, WiFi router, light strip, fan, & antenna) I turned everything on and unplugged the UPS. Nothing turned off, hummed, or changed in any way. After testing a few more times, my TV occasionally power cycled, but none of the other devices tuned off. The TV’s normal power cycle takes 10 - 15 seconds and these were 3 - 5 seconds. It could be a sensitive surge protection fail safe?In the off chance someone is reading this with a similar Xbox / breaker issue - this UPS is an actual fix, not a bandaid. I only intended it to let me save my game after a tripped breaker, but the breaker doesn’t trip when the Xbox is plugged into it.Sine Wave Details: Pure sine waves deliver the exact power needed continuously. Modified sine waves change their output periodically. ChatGPT / Reddit said pure sine waves are only necessary for sensitive equipment (scientific / medical). A deeper dive suggested it’s preferred for tech (computers / TVs) because some devices will make a humming noise. However, none of this is applicable until a power failure and the UPS takes over.
