Do I need to bring an insulated kettle when traveling?

Hot water is usually provided in hotels. If you are going to Europe, bring it, because hotels in Europe don't provide boiled water. It was winter when we went, the temperature was low, and there was no hot water to drink. Our Chinese restaurant has boiled water during the day, but it won't work at night, so it's convenient to bring your own kettle and thermos cup. If you are in other places, you can also bring a thermos pot. It's convenient after all. .
