It makes quite a loud noise when the power is interrupted!! However, it is particularly useful for simple devices!! It is also worth it in terms of volume!!

In the two-year period, a change or battery was needed. I don't consider it to have been particularly inconvenient, as I only use it for the router and the wireless phone (I was not satisfied with the duration in case of a power outage). The CSB battery costs about 20 euros, almost half the price of the UPS and the same as the larger ones (9 Ah). I will try the Sunlight brand for about 11 euros, hoping it will last at least two years, otherwise I will change the UPS.

Honest purchase for 35 euros. Convenient device shape. Easily holds router, IP camera, phone, TV. The noise level is loud and annoying for a living room, especially when the other devices in the room are silent. The specs state "Audible Noise at 1.5M from Surface of Unit (dBA) 40". If I had seen that, I wouldn't have bought it!

In less than 2 years, the battery (5.4 Ah) couldn't hold for even 5 seconds. I easily found another one at a car battery store for 18.50 euros. Besides the computer and the LED screen, I had a router, a cordless phone, a multifunction printer (inkjet printer, scanner, and fax), and a small 9W light for the evening. Okay, I'm not saying that it was necessary to have all of these on the UPS, especially since I didn't use the printer and scanner much. So now I only have the computer, the screen, the router, and the phone. For a simple home user, this specific UPS is a very good economical solution and does its job perfectly. During power outages, you can easily save and shut down your computer, and you can even wait a few minutes in case the power comes back. It's worth its money.

Do not expect to use it for PC, its battery is too small. I have it in the living room for the TV (120w) plus the router and a Raspberry Pi. For such a small load, it is more than enough and I recommend it. Otherwise, go for a larger battery and a better APC for spare parts that your grandchildren will also find.

If you connect it only to a desktop PC, it does something. Otherwise, it doesn't work at all. After 2 years of use, not only does it not work properly, but it also shuts down suddenly while plugged in, without any voltage drops. It's better to go for something better with a little more money

Very good stable here for 6 months
but after a while the battery started acting up... up to about 300 watts for a PC, not more, for example for an AMD APU without an extra graphics card, it's good
