For the loads I have connected, namely a desktop computer, a splitter, a router, and a monitor, I expected it to last about fifteen minutes. Instead, it lasts about seven to eight minutes.

It does its job as it should and in the first few days after I installed it, it kept the computer and the monitor on during 2 power outages.

Very good for the price and reliable.. even though when I first got it and tried it with a PS5 Slim + TV and turned off the main switch for some reason the PS5 did not get power while the TV was ok. It wasn't even close to the Watt limit. I hope I don't have problems in the future (I will update)

Also, I have bought another one from the same company at 900W for the PC + Monitor about 1 year ago and it has saved me many times. That one had no problems

The device works as described. I have connected to it the Cosmote router, the fiber optic terminal, a TP-Link router, the Xiaomi Home Hub, a Xiaomi IR speaker & an LED strip. The UPS LEDs indicate the status as follows:

• Green: All good, fully charged and powered from the grid.
• Yellow with Green: All good, in charging phase.
• Red: In use, power outage from the grid.

The notification sound (beep) is not loud and only lasts for the first 2 minutes, then it stops.

The button on the front completely disables the two Schuko sockets on the back when pressed. If you press it again, it re-enables them.

I highly recommend it — in testing it lasted about 28 minutes. During power outages, a small "click" is heard, with no other noises, indicating that it worked to protect against overvoltage or voltage drop.

Excellent, worth the money, much better than the small ones. The router/light lasts for hours, I was interested in not losing power with the momentary outages we have. For 40-50 euros, it is an excellent choice, I don't think there is a better one.

It seems a bit fake compared to the APC I have, but it does its job. I got it for the router and for a light fixture so we wouldn't be like cavemen during every power outage. When switching to battery, the light fixture flickers a bit, which I don't notice with the expensive UPS, but the router doesn't lose synchronization. Finally, I should note that the beeping it makes during a power outage stops automatically after about 2 minutes, so all is well. At the price of 50, I recommend it with closed eyes.

It's great, in 2 months it has no problems, I believe that the quality of tescom will show over time. I worked with them without issues from 2007 when they started, until 2017. If you don't want something very expensive like APC, you will find a very quality product.

I have not experienced a power outage in the month that I have had it. However, it is small, quiet, I have connected my desktop and router, I do not see it struggling at all. I would also put the laser printer but the printer's dealership prevented me. So I just put a stabilizer there. So far satisfied. I may come back.

I am satisfied with the product. I have had it for almost 3 to 4 months. Yesterday, there was a power outage and my computer screen and USB hub were connected to it. When the power went out, it immediately responded and kept my computer on 100% open. I managed to shut them down afterwards. It is worth the money

This UPS works properly, is silent, and does not smell.
With a very light load (router, DVR with HDD, and 5 cameras), it lasted about 20-25 minutes.
I expected more.
So far, I haven't had the PC on during a power outage, so I don't know if and how long it will keep it running.
Update: It easily keeps the PC on until I shut it down.
Update 2: Its battery lasted 2.5 years; yesterday when the power went out, the PC shut down in 5 seconds.
Update 3: I replaced the battery with a YUASA, and the UPS became like new again.
It was ultimately a very good purchase; I'm adding a 5th star.
