Usb charger smells burnt after use with my phone

I bought and started using my g5s plus 12 days ago, today i notuced a soft bu,zing sound coming from my turbo power charger(included in the box) and i looked into it. While doing this i found my usb port( on the power brick) and the usb connecter( that goes in the power brick) smelt burnt.

I tried another charger thay has been used with a moto e4 before and that smells a little bit burnt too now.

Turbopower is 3 amperes

Does this have something to do with my phone or is this normal?

Should i get my phone replaced(if so is that free or is this noy covered by warrabty)?
