Carry a travel/universal adapter. We didn't have an issue with our mobile chargers but our laptop charger didn't work. We had to go hunting for a travel adapter in an island where there are very few shops and our hotel said that we wouldn't get it. Luckily, we got it in one of the shops.
Indian chargers will work but depends on the hotel or place. Suggest please carry universal supported one you can get it in electrical shop or mobile shops under 150 RS or 200 RS
