Of course, the vacuum insulation electric kettle is good.
At present, the electric kettles on the market that claim to be able to really keep warm include vacuum insulation electric kettles, electric hot water bottles/plug-in insulation electric kettles
Electric hot water bottles/plug-in insulation electric kettles need to be energized to keep them warm. Their functions are similar to those of ordinary water dispensers. They can boil water and keep them warm. After the water is boiled, the heating plate is still heating to maintain the water temperature, but it is easy to form lead waste water, so it is not recommended to keep it warm for a long time. And the price is relatively high, generally ranging from 299 to 1999. It is inconvenient to change water, inconvenient to clean, and consumes a lot of power in the heat preservation state. At present, it is less used in households and is mostly used in offices.
