Is the electric kettle or charge for the notebook?
Books are all college students... Books are open all the time.. You try it for half a month without using the computer.
Unit time is certainly an electric kettle of electricity, it is used in electric heating resistive original, are less 1000W, but on the other hand, he is not to take the electric kettle to boil water to bathe, 24 hours a day, but the books to the Internet, although the power is small, but a long time is not the same you take turns to use, dormitory, all-weather work that 100 kwh.
Common electric kettle power 1000-2000W, 1000W hour, once 2000W, two kwh of electricity.1000W electric kettle boil a pot of water 1/4 degrees electricity, 2000W a pot of water, half degree of electricity (usually two kinds of water kettle is different), burning two pots of water a day, that is, once electricity.My notebook is five hours of electricity, if possible power consumption of your books and I don't like this, but also not much worse, a two day burning pot of water, and one day with five hours of books, electricity almost.
