After several power outages and voltage drops, fluctuations, etc., and even in cases where I was working on the computer at the time of the interruption, I can say that it is a reliable machine. It kept me going for quite some time so I could save my work and shut down the computer (about 10-15 minutes). And because I also have the router connected to it, it kept the internet running until the power returned.
Its operation is fine, quiet, and effective. However, a UPS without the ability to permanently disable the repetitive sound signal while it operates on battery power is unthinkable! Even with the installation of the software mentioned here in other comments, the deactivation only lasts for the current operating period of the computer and then reactivates, which is completely unacceptable. I cannot tolerate hearing that beep, beep, beep every few seconds. Why does it have to annoy me every time? And why do I have to wake up in the middle of the night because of it in case of a power outage, for example? A major reason not to prefer purchasing this particular machine!
Bought last week. Small, takes up little space, quiet with the screen showing battery status, load it carries, and output voltage. Download the UPSmart app for additional settings and detailed information about the UPS and to set the times when connected devices will shut down. I have my PC and monitor connected. In a test I did by shutting down the general power, the UPS battery responded immediately. I left it on for 5 minutes with a load at 40% and then shut it down without any problems. The app said the UPS battery still had five minutes until it shut down completely. Before testing it, charge it for 5-6 hours to have the full power of the battery.
Externally very small and relatively (based on power) light. Good and informative screen. Completely and absolutely silent. No plastic smell during use. So, very good external impression. But how long does it last in case of power outage? Here I cannot give a proper review because I have only connected 2 routers, 2 USB hubs of external hard drives, a wireless phone base, and a smart TV box, i.e. devices with low consumption. In my case, it works correctly and lasts forever.
I bought two that have USB ports for connection to a computer.
The USB ports are there for connection to a computer. Some UPSs either support direct connection to the computer, while others require software installation to be able to "communicate" with the UPS.
The computer can shut down if the UPS level drops below a point that we define. It is good to shut down before it drops below 40%, ideally 60%.
There was no CD/DVD or at least a reference in the packaging for me to download their program (or any of the free/paid programs available on the internet).
The bad thing is that searching on the internet and reading reviews, I did not find any specific program that supports it. I downloaded NUT and apcupsd but I couldn't connect to the UPS.
With other UPS brands, as soon as you connect the USB, the computer sees it as a battery, so even from the computer's operating system, you can set rules for the computer to shut down if it drops below, for example, 60%.
I called Tescom Hellas today (2109590910) and by selecting the option for the technical department, it took me to voicemail and I left a message...
I am not very satisfied. They are certainly more affordable than other brands (I heard they are made in Turkey), but if during a power outage the devices are still running and there is no one present to shut them off, then the batteries will drain, they will be damaged because they drained, and the machines will turn off as soon as the UPS shuts down.
If I receive a response from Tescom, I will edit my answer.
Update: The software is called "UPSmart" and specifically for the models I bought, the version "UPSmart for EA protocol(G3 G2)" needs to be downloaded.
After installation, in the program settings, in Monitor mode, we need to select "Mega(USB)".
Unfortunately, the program is not flexible and the mail notification never worked.
I set up a schedule to test the batteries every week and programmed it to shut down the computer when the battery level drops.
During a short power outage, it worked perfectly. Only the modem and the CCTV circuit recorder are connected to this machine, so that they can operate smoothly even in case of power cuts, which unfortunately are very frequent. Before purchasing the machine, I spoke to a TESCOM technician, to whom I mentioned exactly what I wanted to connect. He told me that because the connected devices have very low power consumption, even during a long power outage, they will all operate as if they have power. The machine's power coverage reaches 8 hours, as the technician assured me. In other words, it fully covers my needs.
Good for desktop, you have the margin to safely shut down the PC during power outages, it makes a noise when operating on battery power, when it is plugged in you can't hear anything, it also has four sockets where you can plug in the monitor. Otherwise, time will tell with such devices... see battery life.
