Abstract: A test method and apparatus for an adapter, and a device and a storage medium. The method comprises: detecting the temperature of a component in the adapter (S101); determining whether the adapter is in a temperature balance state or not according to the temperature of the component in the adapter (S102); if the adapter is in the temperature balance state, raising the ambient temperature of the environment where the adapter is located (S103); detecting the output power of the adapter, and determining whether a power-reduction operation occurs in the adapter or not before the temperature of the component reaches a first preset temperature threshold (S104); and if no power-reduction operation occurs, determining that the adapter test fails (S105). The method takes the temperature factor into consideration in the test process of the adapter, and detects whether an overheat protection mechanism exists in the adapter or not, thereby ensuring the safety and reliability of the adapter passing test.
