good model, done well
10 December 2025 
Who knows how long it has been working for me, but I have definitely replaced the batteries several times. There's an ordinary small 12-volt battery inside.

It has a decent weight—you can feel it when moving it from one place to another, yet it's pretty compact in size. That's quite nice.

During power outages, it really comes to the rescue: it gives you time to save your work, properly shut down your PC, or endure short network fluctuations. Not a generator, of course, but it works excellently as "insurance." Or, with some manipulations, you can turn it into a small charging station. The problem is that recharging will take a lot of time. There are plenty of video tutorials on YouTube now, including how to install larger batteries and what needs to be added or soldered. But in the end, you will get an 800 W charging station.

As for a model in this class—it's quite a reasonable and reliable option. It's pretty simple, so it can work for years; just replace the batteries as consumables.
A reliable non-reliable solution that has been on the market for a decade, not a big one.
The batteries from the store are so-so.
