The 690 watts it claims can't be sustained, not even as a joke. My computer with a load of about 620 watts at full load shut down during a power outage with the battery fully charged. It's only worth it for light systems/devices.

Excellent product. We bought three pieces for the company. During all the blackouts that occurred, they worked perfectly. One is connected to the telephone center and router, the others to two iMacs and one iMac respectively. I can't say about the duration time, but once when the outage lasted about 20 minutes, they were still there providing power. We highly recommend it.

I live on an island, so power outages are frequent. Both times I needed it, it lasted long enough for me to safely turn off the TV and Playstation.

during the first blackout I didn't manage to shut down the pc. it lasts a few seconds. unacceptable. waste of money.

Every once in a while, I unplug it to let the battery drain. It would be good if it could empty out to maintain the battery's life. No issues.

Today the power went out, and on a PC with a 750-watt power supply, it comfortably lasted the 20 minutes it took for the power to come back.

UNACCEPTABLE and the dealership even more so. 1150VA, 7.5Ah and a 70W device with 2.5A didn't last even 30 minutes.
I contacted the dealership and they don't allow you to speak directly with a technician. A staff member answers who asks the technicians. The response?? Well, 30 minutes is just fine, UPS are meant to give you time to shut down the device!!

Waste of money!

It is the ideal solution for uninterrupted power supply to small devices. I use it for the operation of the router and I am at ease because I always have internet and phone during power outages.

Unacceptable. I have only one modem router on it and it doesn't last even 2 minutes. I put a bigger battery in it and still the same. Waste of money!!

Very good choice for desktop computers. Good battery life, you have the time to save any work. Value for money!

Cheap but with a short battery life (3-4 minutes). After 3 weeks of use, it still smells.

Unfortunately, it is not what I expected. If the power goes out, it only holds for a few seconds. I only have it to keep the output voltage stable on the modem-router and alarm system.

I got it to deal with short power outages and voltage drops. Easily 5 stars as when such unexpected events happen you continue your work as if nothing has happened. Ideal for me.

Within three months, with the first power outage, both immediately turned off. After speaking to the supplier who responded immediately to my needs he gave me directions on how to activate the ups by pressing the button down for longer than three seconds before plugging it in (i did not know that since upon purchasing i plugged it in and it worked with the first power outage and lasted) now i will have to pay attention to press the power button to activate the ups in future

At a pretty good price and since the old UPS broke down 5 days after the warranty expired, this one is the best at this price (under 50€)

I connected the fiber box on top to have internet since the router gets from mini. ups. I took it out of the socket for testing and it lasted 7 minutes new for a week. consumption is 12v 0.5 A 6watt. I expected it to last at least 5 hours. unacceptable. wasted money.

I bought two pieces to connect them to boilers so that they can keep me going for a while in case of a power outage. So far, everything is good

It says 690w but it can't even handle 300w. I have a gaming desktop with a 550w power supply and during a game with a load of 350w, when there was a power outage, it shut down immediately and so did the computer. This is an unacceptable product, stay away from it. You would think you have protection from the surge, but this will burn your computer. Stay away, get something better.

I have it for a while, maybe 2 months if I remember correctly.. At first, it smelled like plastic. I had it on the balcony for 2 days and it was fine. Now it's fine, it lasted through all the power outages and tests.

I have it connected exclusively to a desktop computer and monitor, I cut off the power for 5 minutes to see how long it lasts and it didn't go off (the computer was idle, so presumably if it was under heavy load, the runtime would be significantly reduced). I didn't notice any plastic smell, nor does it make any noise, it's fine.

The best at the most affordable price.
I have connected it to a 550-watt desktop gaming power supply and a 24-inch monitor at 144 hertz, and after 5 months of use, it responds perfectly to voltage drops and 3 power outages, very satisfied. For 3 weeks, it had a plastic smell that disappeared after heating up. Today, on Feb 16th, I bought a second one and I am 100% satisfied, so I also bought one for my second computer. I have had it plugged in for an hour and so far, no plastic smell has come out, we'll see... On Feb 17th, after 24 hours of operation, there is no smell, so this batch is OK.

I bought it for a PC that consumes ~600 watts. With the PC at full load, it immediately complains about overload. If the power goes out while it's at full load, it shuts down without warning (it doesn't do its job). It works fine at lower loads. I use it as a voltage stabilizer and as a UPS for 3D printers. For its price... it's okay

I have a PS4 and a 55-inch TV. I've had them for months without any issues, but yesterday the power went out. The PS4 made a loud noise to alert me, and within minutes I shut everything down. It all shut down smoothly and quickly.

I have it on a c2 and ps5 and the only thing I have noticed is that when the TV has the entire screen in yellow color, the UPS gives an error for 1-2 seconds, I don't know if it's because of HDR drawing more power. It hasn't been necessary for me yet as I haven't had any power outages.

I just received this product and I have no opinion on its quality or durability over time. I ordered it to connect a pellet stove, as the power frequently goes out on the island where I live and in this particular house. It takes about half an hour to reset the power and then reopen the stove. During the first test, I intentionally cut the power to see if it would keep the stove open, and it did. I don't know if it will last because I didn't buy it for that purpose. In any case, I will come back in the future if anything changes.

After one month of use, I have no complaints, the power has not been cut off yet, I will return to evaluation when it happens.

The windows have been open for 3 days and there is still a suffocating smell coming from the plastic, logically it must be warm in the back even when it's on standby. When the power went out, it lasted for 1 minute and the UPS kept the power on for my 24-inch screen that burns 25 watts. I will update you later.

2. So, the UPS still emits that smell after 5 months. It's good because it saved me from many power outages and provides clean power. But it's not suitable for a space where people are nearby. So, I placed it in the warehouse after making a hole in the wall for the cable to pass through. Finally, I breathed clean air!

Simple UPS for office use. I don't know how long the battery will last over time or if it's easy to replace, but for the money, it's great. No screens or anything like that.
