Severin Li20 handheld vacuum cleaner

Portable vacuum cleaner with Li-Ion battery. Two chargers included: regular one + one with cigarette lighter plug.

Initially it was charging but not giving any life signs otherwise.

Charging: barrel plug socket on the left. Charging cradle that can be mounted to the wall allowing to hang vaccum cleaner on it is included.

Battery pack - two 18650 cells. That's a plus - it would be easy to replace and 3C cells would be good enough. Given that this vacuum cleaner is a current model, it looks like this battery was made in 2023 / date code starts with a year.

While it is advertised to work with liquids, I doubt if this would be a good idea.

TX-CF02B.1 board. There are no markings on the 14-pin IC (most likely charging controller).

The fault: cold solder joint on one of the wires going to the power switch. It looks a little bit like a broken trace, but it was just the soldering. Just in case I've resoldered also all others cable connection points.
