How am I supposed to soldering this? I have both soldering iron and a spool of solder. But most videos show soldering wires instead of what I need as you can see in the picture (disconeted cable on a laptop charger). I would higly appreciate any info and tutorial videos on this.

It’s definitely possible to repair, the question is whether solder is sufficient, and if so, what kind of solder and what are the risks. It looks like it’s 220V and I have never soldered anything but low voltage DC. A bad solder could mean high resistance->heat->fire though it’s out of my expertise to speculate further.
Here’s what I would do. Find a quality power connector from an electronic device someone is throwing out, and cut it off leaving some excess cable (Or buy online if money isn’t an issue). Then, cut off the ‘faulty’ connector on your device. Solder or crimp together the replacement connector with the existing charger wires. Bonus: Use heat shrink tubing to provide a safe insulated secure connection (1 for the + wire, 1 for the - wire, and 1 larger one to go over both +/- wires as the external jacket). This should give you the most elegant repair. The heat shrink acts to slightly as a mechanical load distributor, so you don’t stress the crimp connectors or solder when moving the charger around.
