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 adapter

Before 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 plug

Power 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 cord

Insert 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 terminal

Select 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 devices

Connect 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 power

Switch 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 equipment

At this point, the electronic device should have received power from the power adapter and can be used normally.

matters needing attention

Voltage 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 upkeep

Cleaning: Regularly clean the surface of the adapter to prevent dust accumulation from affecting heat dissipation.

存放：不用时，断开所有连接并存放在干燥的地方。

使用技巧

节能模式：部分适配器可能具有节能模式，长时间不用时可以切换到此模式，降低能耗。

备用电源：如果有条件，可以为关键设备准备备用电源适配器，以防原适配器故障影响使用。
