All hotels in Brazil will not prepare disposable slippers, toothpaste and toothbrushes for tourists, and tourists will prepare them themselves. The voltages in Brazil are 1 10V and 220V, and the voltages used in major cities are different, so tourists in China must pay attention to the applicable voltages before using household appliances.
