Desktop power adapter is a common power device that is typically used to provide stable direct current (DC) power to electronic devices. These types of adapters are usually designed to be placed independently on a desktop due to their large size, rather than being plugged into a socket. The following are the general steps for using a desktop power adapter:1. Understand the specifications of the power adapterBefore use, first check the specifications of the power adapter, including input voltage range, output voltage, output current, and other information. These information are usually clearly labeled on the casing of the adapter.2. Check the power cord and plugPower cord inspection: Ensure that the power cord is not visibly damaged, such as exposed wires or cracks.Plug matching: Confirm whether the power cord plug meets the local power socket standards.3. Connect the power cordInsert the power cord of the power adapter into the input port of the adapter and plug the other end into a wall socket or power extension cord.4. Connect the output terminalSelect the correct output plug (if replaceable) according to the requirements of the electronic device being used, and insert the plug into the output port of the adapter.

5. Connect devicesConnect the output end of the adapter to the device that requires power supply through the corresponding connection cable (such as USB cable, circular plug, etc.).6. Turn on the powerSwitch control: If there is a switch on the adapter, it needs to be turned on.Indicator light confirmation: Observe whether the adapter has an indicator light on, indicating that the power has been turned on normally.7. Use of equipmentAt this point, the electronic device should have received power from the power adapter and can be used normally.matters needing attentionVoltage matching: Ensure that the output voltage of the adapter matches the voltage required by the device, otherwise it may damage the device.Current limit: Do not exceed the output current limit of the adapter to prevent equipment damage or fire risk caused by overload.Proper placement: Ensure that the adapter is placed in a well ventilated area, away from heat sources, and avoid overheating.Maintenance and upkeepCleaning: Regularly clean the surface of the adapter to prevent dust accumulation from affecting heat dissipation.在家中存储：只用时，段开各种连结并在家中存储在晾干的的地方。的使用技巧攻略节能减排环保方式：环节兼容性测试器将更具节能减排环保方式，长时段没用时是可以调成到此方式，有效降低万元产值能耗。
