karanchadha As I am aware that Nothing only sells genuine accessories on Flipkart only, not Amazon. The charger you got is obviously a duplicate because there are a lot of duplicates on online sites and second, it’s must have been cheap too(like 1K). The original charger costs more than 2K INR.
I got a year of warranty by the store I bought it from, despite it being a 45W charger, it will charge my phone around 25-29W because this is intended to protect the phone and charger from overheating which they still do in a well ventilated cool room.
High chance that the Serial Number might be a copy.
Oopsies!
