Pros

Cons

Not suitable as uninterruptible power supply, only for manual connection.

For 4 months they haven't fixed the UPS operation, which turns off the output sockets during short-term disruptions in the city power grid. The manufacturer claims it can be used with equipment sensitive to power supply, thus deceiving customers! The problem has been known for a long time and remains unsolved.
Power and energy efficiency, design, functionality, convenience.
In fact, the UPS function does not work; almost every time there is a short power outage, all output sockets turn off immediately. Even after following the tech support recommendations, the result is unchanged. While operating from the network, fans may periodically turn on for 1-2 seconds, and over time this becomes annoying.

The device was needed to power the apartment after the power outage. It performs all its duties.
The chemistry of the power elements allows you not to worry about their preservation and economic use, charge to 100, discharge to 0, everything is fine. The back cover is recessed into the body, a trifle but pleasant. The firmware unlocks several cool features in combination with other devices. Smart protection system for short circuits, extreme values, curves, etc. Intelligent systems for use in various cases.
there are no bags and cases for the device, I have no complaints
