The K650VA AVR UPS Line-Interactive 650W with 2 Schuko Sockets by Lamtech is a Tower UPS with 2 Schuko type sockets. Its operation is (VI) Line-Interactive, which continuously adjusts the output voltage through an automatic voltage regulator, protecting against voltage fluctuations and power outages.
Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
I just bought it. I can't give an opinion on its durability yet. However, I have connected my computer to the UPS and I'm waiting for it to fully charge (12 hours according to the user manual). The battery (according to the user manual) lasts for 20 minutes (I tested it with a 850W desktop and after turning off the power, it worked perfectly, as if I never changed the power supply from 500W to 850W. However, even if it lasted for 5 minutes, I believe it would be sufficient to safely shut down the desktop or any connected device.
The desktop I'm using has a 500W power supply (recently purchased gaming PC 2022) (I changed it to 850W and it continues to work normally!).
5 minutes on a 850W PC (after changing the power supply from 500W to desktop) along with a 55" TV + capture card and it worked satisfactorily on power, only the TV screen was flickering, so I do not recommend connecting the specific 55" device to this UPS (laptop 15-50W + desktop 850W) is okay.
PS: It has 2 socket outlets (type socket), three lights, one red for the battery, one green indicating power, and one yellow which is presumably for power outage (audible warning) according to the instructions.
It also has a simple instruction booklet (a paper with basic instructions written in English).
Easy to use.
Finally, I want to emphasize that if you buy it, don't be surprised if you plug it in and no light turns on. Press the on/off button for a long time (1-2 seconds), you will hear a characteristic beep, and leave the UPS for 12 hours to charge.
I hope I helped for now.
After 6 months of use, I have to say that for a 40-55" TV, I was able to watch for 20 minutes without power along with the provider's router on top.
Also, for a computer with 500W - 850W, it easily provides power for 5-15 minutes, I haven't tested it for longer.
I have a PC with a Ryzen 5 5600, a monitor, and the router, and during a power outage, it lasts exactly 5 minutes... (I don't know if that's a good time; it's the first time I've used a UPS)
*** update*** 2 years after the purchase, it doesn't last even 1 second during a power outage and shuts down the PC as if the UPS doesn't even exist...
Once the power went out, it worked, and another time it didn't work. And we're not talking about some big desktop, we're talking about a simple low-budget mini PC.
After a few months, the computer started shutting down on its own, which made me worry and fear that my PC was broken, but in the end, it just happened out of the blue.
I won't bother dealing with service, etc., my time is extremely valuable. I simply won't buy a product from this company again.
It is definitely value for money. With a 250w computer, a 50w monitor, modem, and router, it lasted 20 minutes. It is silent as long as there is mains power, and after the power goes out, there is a slight buzzing from the battery which is normal, and an occasional beep that can be turned off by pressing the button once briefly. However, when the battery is almost empty, the beeps become faster and there is no way to turn them off, making it extremely noisy and annoying. Also, the software for connecting to the computer comes on a CD and its version is nowhere online (I will try to upload it to some forum on insomnia when I find a device to read it)
Stay away. It cannot handle a Starlink router on its own, which consumes a maximum of 75W. And it claims to be 720W. People are laughing.
I have connected a 250W printer and a 48W filament dryer on it (total of 298W) and when I tried to operate them together, it started whistling and turned off. So, 650W is definitely not a joke.
I have the 800VA with a router and an alarm system, after 1 year of power outage it lasted exactly 5 hours.
Coming from an old 20-year-old UPS, I have to say the following:
1. It is completely silent.
2. I have connected a computer, a monitor, and the Cosmote router. It easily lasts for 15 minutes, which is more than enough time to shut down the computer.
3. Very good price.
4. Small in size.
Impressed. Highly recommended.
The previous model I had was better than the one they offer now, but this one also does its job. 4 stars only because it would sometimes open and close on its own, but it could also be due to the power socket. Overall, it's worth its money.
I have it for about three months. So far, it's very good for two connected low-consumption devices. Quiet, without any problems.
Very good economic solution for 2-3 devices, recently we had a power outage, with a stable router, charger for mobile and laptop loaded on top it lasted about 50 minutes, while it struggled when we also connected the TV, ideal solution though for 2 devices, quiet and with small size and volume, easily convenient.
