Hello Liam, when you say power bank do you mean your portable charger?

If you can give more details?

My xbox power brick makes a weird noise when i turn it on sometimes and i don't know why someone please help me

What colour is the light on the side, and what sort of noise is it? The original power adapter does hum a bit, but yours must be noisier than normal. If you're smelling any electrical burning there could be a problem, otherwise its probably just old so there's
nothing to worry about. Keep it away from anything flammable, just in case

The light is green and yes the donkey scenario fits perfect though it eventually stops for some hours, it's not so bad since I wear headphones all the time anyways.

No electric or other smells.
