Different schools are different. Generally, in the old campus, there is little management in this respect, and the voltage is stable, so it can generally be used. We use two rice cookers, 1 electric kettle, two hair dryers and four computers in our dormitory, all of which are fine, and there is no electricity jump. However, the new campus of our school stipulates that only 40 kwh of electricity is allowed in a month, and it is easy to trip when the hair dryer is turned up. There are not many teachers in our old campus to check whether there are illegal appliances, but there are often surprise inspections in the new campus!

Our school is like this. Different school systems and equipment are different. You can use it secretly without being caught. As long as you don't jump, everything will be fine!
