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.

    Don’t forget to add flux to the joint! Especially for large ones like a charger, the “flux core” isn’t going to be enough. That core is just to keep the flux present as the solder flows, it won’t help remove the oxide layers from the surfaces before starting.

    And use a temperature-controlled iron if possible. Much more likely to work properly, less likely to destroy the board by lifting a pad. 350°C should be plenty for most solder alloys.
