I am referring to the 2000VA / 1200W.
I have been using it on my main PC for 50 days. Max consumption along with 2 monitors, 34' and 29', is 530w (max cpu/gpu usage).
There could have been an option to turn off the UPS screen. The manual states that if you press and hold the button, the screen turns off, and if you press it longer, the UPS turns off completely. This does not apply to me, at least. Perhaps the button is to blame, which I wouldn't describe as very high quality. The panel is nice with the basic and useful information. Sturdy construction and at a good price. They are not bulky, and the noise doesn't bother me since I have it downstairs and I consider it silent. The sound when there is a power interruption is not loud either. As for the smell at the beginning of its operation... the air fryer I bought a while ago smelled x10 times more.
Don't pay attention to such details. They could have at least provided a 2m USB-A / USB-B cable.
There is an idle consumption of around 20W, and the reason is that it operates continuously to stabilize the voltage while constantly charging the battery. This is normal, and it's good to keep it always on!
Positive is the existence of Greek service!
4 stars for the button.
Nevertheless, I will buy x2 900w for my children's computers.
Purchased in December 2024. So far, it works normally as one would expect. In a power outage test, it activated immediately without the computer noticing the change. It powered a PC with a 650W power supply (this doesn't mean it "draws" all 650 continuously), a 21" monitor, and the router for over 10 minutes, and it could have lasted longer, but I stopped it because I didn't want to "over-discharge" the batteries.
During a power outage, it makes a characteristic sound that it repeats about 10 times and then stops. The output voltage is consistently 230V, so it has a stabilizer, which, however, does not work during normal operation (because it is line interactive) and provides the network voltage, which in my case is 243V.
The display is impressive with a plethora of indicators such as output voltage, battery charge level, supported load, power status (mains power or batteries), etc. As previous users have mentioned, the display does indeed have somewhat intense lighting, which may bother some, especially if the UPS is located in a resting area.
Also, when first powered on, it emits a smell characteristic of electronic devices that have heated their plastics. Since fully charging the batteries takes about 8 hours (according to the manual), it’s good to keep it on a balcony during these hours until it dissipates the unpleasant smell.
This review, therefore, concerns the first impression of the UPS. I will return in the future with its performance over time, which is the most important aspect of these devices.
I got it a few days ago to support:
1) ONT (2.5gbps).
2) Mini-PC with 4x2.5gbps that works as a router.
3) 2.5gbps 8 port switch.
4) POE Switch with 3 POE devices.
5) Intel NUC Mini PC running Proxmox and hosting services.
6) Synology NAS with 2 drives.
7) Wifi AP.
In general, it is 7 low-power devices, and from the UPS screen, it shows 1 line on the load, so it should last over an hour for all these devices.
It is inside a rack along with the devices I mentioned.
I had 2 power outages since it arrived, and it seemed to hold up just fine! It beeps a few times in the first minute and then stops. If you look at my reviews, I had a terrible experience with another UPS from CyberPower that squealed like a pig, only it had a power strip on it with no load. This one is much, much less noisy, but still, I wouldn't put it in a bedroom.
Now, a negative? I connected it via USB to my Synology, and for some reason, they do not communicate, although the Synology recognizes when I plug it in or unplug it; if I plug or unplug the cable, it does not receive statistics from it, and so I will have a problem if the power outage lasts for many hours, and it will never receive a command to shut down before the battery runs out. I will talk to the representative tomorrow to see what can be done.
Edit: 12/6/2024
I spoke with the representative on the phone provided by another member here in the reviews, and they informed me that for the USB to work, it needs to be connected to a PC running either Windows or Linux and their own program, so the problem I have with the Synology cannot be resolved. They provide the program via email upon request.
I will not go for a replacement as beyond this, I am satisfied with the product and the price:quality, but if someone wants it for the Synology NAS or possibly other NAS, they should look for another solution.
Now I want to see if I can run the program on a VM, either Windows or Linux, if it can function as a network server to be connected to the Synology.
It seems to work as it should, although I just installed it. Coincidentally, there were also two power outages, so we saw it functioning in practice. The little screen with the information about the power, load, and battery capacity is nice. Another positive is that in case of a power outage, it doesn't make a continuous sound, but only a brief alert to inform that it has activated and just before it turns off when the batteries are almost depleted. The quality of the batteries and the protection it provides will be evident over time.
Smell of melted plastic during the first week of operation, which has now stopped. The only negative I would mention is the intense brightness of the screen that cannot be adjusted and is somewhat annoying at night
Satisfied so far, on some occasions when the power was interrupted, it responded without issues. I chose it because it had 4 sockets. The reason I won't give it 5 stars has to do with the cable being relatively short, but this is also a problem of old houses; in new ones that are designed better, there are outlets where you need them.
Very positive. 1) 50' TV 60-70 watts consumption, AUTONOMY 70 minutes. PC Tower and monitor 100 watts consumption, AUTONOMY 48 minutes. 2) Silent. 3) As a slight negative, I would say that the screen light is bright; at night I would prefer it off. If I had known in advance that there is an app to control it, I would have bought the same product without the monitor, just the one with the three small lights. OTHER THAN THAT, WONDERFUL
I use it for the router, modem, raspberry pi, and zigbee gateway (for home assistant). The load does not exceed 3%, with the need to be for the above. I definitely want 1 hour of endurance for this, so I chose these specific specs.
I have utilized it to the fullest (and USB for communication with the RPi via upsnut) and for protection in case of overvoltage in the DSL wiring.
It makes some beeping at first but then stops. With the USB connection, I have the option to mute the beep more quickly.
Its disadvantage is that it still smells even when in online mode, which is a bit annoying especially after 1 month. Of course, I have it in a hallway, but it is regularly ventilated. That's why -1 star.
Anyone who wants to do monitoring on Linux, this is the configuration for NUT:

I have successfully connected it to home assistant
I recently bought this specific UPS (900W), so my review will be brief. As for the material quality, it is very good; it has nothing to do with the brittle plastic I have encountered in similar products. The main thing is that even though I have only had it for a short time, it has saved me from 5-6 power outages without the slightest problem. And to conclude, I would like to add that the panel (monitor) is beautiful with the necessary indicators for monitoring the functions. It is connected to a 24' monitor, a tower with a 260W power supply, and a 4G router. It hasn't stopped for a minute since the day of purchase.
Very respectable, very honest, and so far it has proven to be a champ during all the consecutive power outages we've had due to bad weather and DEH's work, a situation that I would say is permanent for us. It functioned protectively during outages when the power would return for a few seconds, drop again, and then come back. It didn't notice anything and protected the PC without the slightest problem, while also giving the necessary time to complete your tasks and shut down if you were on the computer at that moment, or simply to have peace of mind during the consecutive outages that you wouldn't find your belongings toasted. It always has an audible alert so you know exactly what is happening. I also really like its design; it's an aesthetically pleasing and beautiful product to see on your desk. There was indeed a strange smell specifically when it was called to function during the power outages, what friends here say in the comments is true. I don't know exactly what it is, but I didn't notice anything else strange happening. If any friend has an answer to this, please write it here. The screen is also very good; even if you are a beginner in these things, you understand what you need to do and what it shows. You just plug it in, connect the computer and the screen, and let it do its job. Now I will get two more. Worth it.
Nice ups. Design and nice screen. 2 sockets. At first it held normally, managing to close the windows. Now, after less than a year of use, it holds for the tower and the screen for a few seconds. About 20-30" which is not enough. I now have it more as a voltage stabilizer than as an ups. 3 stars moderately.
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.
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.
