My Macbook Pro (2017) 61W power adapter only supplies 12W of power.

My Macbook Pro (2017) 61W power adapter only supplies 12W of power. Why is that and how can I fix it?

The problem started occurring last week. The charger has always been fine, then it suddenly couldn't supply enough power when I'm working on it. The power slowly drains until it dies. I tested the 30W charger of a 2018 Macbook Air and that one supplied the full 30W power on my Macbook Pro... My charger however still supplies only 12W on the Macbook Air. (My Macbook Pro's battery is still in normal condition.)

MacBook Pro 13″, macOS 10.15
