The VFI 1000 TG UPS On-Line 1000VA 900W with 4 IEC Outlets from Powerwalker is a Tower UPS with 4 IEC type outlets (like those of computer power supplies). Its operation is (VFI) On-Line/Double Conversion, which continuously provides power from its battery, protecting against voltage fluctuations and power outages. Its battery can last 10 minutes at half load or 3 minutes at full load (when the connected devices draw half or the maximum current the UPS can provide, respectively). It offers pure sine wave power, which is suitable for sensitive devices (e.g., medical equipment) and is preferred for devices with power supplies that have active PFC protection (e.g., computers).

I have it for 2 PCs/screens, 1 router, and an IP camera. Very useful. You plug it in and finally relax. It can also provide very easy absorption since it protects a bunch of sensitive devices that are full of electronics that can break for many reasons.
I prefer VFI over VI that everyone goes for because it provides more protections.
Such as isolating devices from the network and protection from power surges. I have also added a surge protection socket at the input.
Protection from voltage drop and surge... It automatically keeps a steady 230V even when the voltage in my house drops to 210V.
When the power goes out either because the relay or a fuse has tripped, or due to a power outage from the power company... the warning sound it makes every few seconds is not annoying. It also has a Silence button so you don't hear anything, it also has settings to be off.
One negative thing it has is that it works continuously and you can hear 2 fans like you hear from a PC. It doesn't bother me at all, the constant sound it makes is positive for me, but I think many people want them to be silent. When it is loaded above I think 70%... the fans go to 100% and it sounds much louder. I don't see any settings to make the fans not work continuously.
The other negative thing is that it consumes slightly more power than a VI. Now it's a bit difficult to tell you accurately, I don't know for sure, but I estimate it to be from 20W to 50W more, compared to not having any UPS. I think it depends on the input voltage and the loads.
The other negative thing it has is that it constantly lights up a blue screen with quite intense illumination and I don't see any settings for the screen to tilt.
When you get it, you plug it into the socket to charge the batteries to 100%, then you connect the loads, press the button to start supplying power to the outputs and you're ready.
Keep in mind that it should not be placed on the floor because it collects a lot of dust, since the fans work continuously.
