Can you just unplug the charger when the wall outlet makes a crackling noise?

There is danger. If you go to the back, it may cause a short circuit in the household circuit or even spontaneous combustion and cause a fire. You cannot unplug the charger directly by hand, you must use an insulator to insulate it.

1. Power failure: Check whether plugs and sockets are empty or have poor contact.

2. Eliminate the differences! Try logging in again.

3. Replace the different parts and try again! Restorable.

Reason:

1. Sizzling Noise:

This is the discharge (spark discharge) between the "plug" and the "plug" into the combustion air when the power is turned on. The sound produced by oxygen! The reason is the result of poor contact between the two. 〈Generally refers to: “virtual connection” and “one-time connection”〉

2. Intermittent connection:

Whenf there is a virtual connection, the electrical fire burns the contacts! Electricity will lead to failure! After cooling, reconnect! It comes and goes, which happens frequently.
