I have had it for several months, the first months it smelled burnt, it started with the first power outage to whistle 3 stars because it can't handle the PC when I play Cyberpunk and for the noise

I have been using it for a year and a half... even though I have it on my computer as a filter and UPS to save work, etc. WITH TIME COMFORT, I also got it for the VoIP of OTE, which takes more than ten minutes to come back after a momentary interruption. It works perfectly and saved my machines during an extensive voltage drop in the area!! Its panel is very good for testing and seeing network fluctuations!

In the past two months, a high-frequency sound started to be heard in silence and it is quite annoying. The battery doesn't last as long as expected and the software is rather mediocre. The noise is ultimately coming from the transformer and doesn't go away no matter what. You don't notice it with the computer on, but in silence, it is torture. It also reaches quite a high temperature. I completely got rid of it.

Enough for two PCs in my case. The only downside is the strong smell in the first few days until the plastics are heated.

Indeed, I will agree with the above friend, the machine is a beast even though I don't have many things connected to it - just 1 desktop + the monitor and speakers (17-18% UPS load). I don't even touch it with 1500va. What I like is that through its software, you can perform many tests to see how long its battery will last. Time will tell, but I think it's a good value for money

Very powerful ups. Especially for Pc, ps5, laptop, TV it doesn't understand anything. It has 2 batteries and makes noise when the power is cut ⚡ because the cooler starts working. It has a green lcd screen with Voltage in and Voltage out indication as well as autonomy, workload, etc. I got it directly from Green Cell. Honest for its money and likely to produce a very good sine wave.
