Capacitors are dangerous! - Mi Air Purifier Repair

Capacitors in power modules can hold quite a lot of charge even when disconnected from the mains.

This is exactly what I demonstrated in the repair video below, where I replace the power module of a Mi Air Purifier Pro that belongs to my brother.

The original power module of the air purifier failed with a bang because of the leaky capacitor, just after the warranty period was over so I decided that I will repair it myself.

Full written instructions for the repair can be found in the Instructable article.
