Off course not, Electric kettle consumes at least 700-800 Watt power or more depending on the size of the kettle whereas these sockets are provided for less power consuming appliances like for charging mobile, laptop or trimmer. Some people abuse the facility and thanks to our globalized world, dual voltage appliances are also present which can function on both 110V and 200V without any trouble.
But nowadays, under most of these sockets, there is a notice displayed to the effect - Only for charging mobiles and not laptops etc. I find quite many techies boarding the train, occupying their berth and keeping their laptops charged throughout their entire journey, watching movies or doing office work. If a passenger like me wants to charge his mobile, you will have to request them and they feel they are doing a great favour by letting other passengers use the charging point.
Ya, I have seen those stickers too but still a Laptop Consumes max. 100 watt but an electric kettle is definitely unacceptable. BTW some tips for You sir, either carry a Power Bank or a USB cable and charge your mobile by connecting it with those techies' laptops too. For even worse situations I carry a three pin too...:D
