Starwell’s desktop power adapter with a rated power of 300W. Its core feature is equipped with an independent power switch button. Unlike common adapters, this switch button enables users to directly and physically cut off or connect the output power of the adapter without unplugging or unplugging the power cord. This design brings significant convenience and security in use: users can easily and completely power off connected devices without frequent plugging and unplugging, which helps achieve zero standby power consumption during non-use periods and is energy-saving and environmentally friendly. Meanwhile, physical switches can effectively prevent the potential risks of abnormal currents such as lightning surges and extend the service life of equipment. This adapter typically adopts highly efficient and stable switching power supply technology to ensure a continuous and stable DC voltage output under different loads.
