Solder

If there's a way around having to solder something you need to work, and you have no real previous experience, then don't solder if it involves soldering on circuit boards.

In this case, I reckon you should def go for the converter.


Alos, if you want to learn, go for really easy stuff first, stuff you can toss out if it doesn't work. Try removing and replacing some solder on a circuitboard you don't need, like something out of an old walkman. Then you can put it together and see if it still works.
