How do I know an apple 20W charger purchased from Amazon is original or not? (Country: India)
On the grey end with the prongs which go into a power point/wall socket you should see a small Apple logo with the text: Designed by Apple in California, or you will if you use a magnifying glass - the font is very small.
That presumes you have received it. If you have not yet received it and it is not what you ordered you are entitled to a refund.
Or you could order it online directly from the Indian Apple store.
