Standard power adapter:

Standard power adapters are produced according to specific electrical and mechanical standards. These standards are usually developed by international, national, or industry organizations to ensure the safety, compatibility, and reliability of equipment. The standard adapter follows a unified specification defined by specific standards, such as input and output voltage, current, plug type, etc., to ensure that users can exchange adapters between different devices. Common examples include USB chargers that follow the USB Power Transfer (USB-PD) standard.

Non standard power adapter:

Non standard power adapters refer to adapters that do not comply with General Electric and mechanical standards. These adapters may differ in design, voltage, current, or plug type, making them incompatible with exchanging with other devices or standard adapters. Non standard adapters may pose performance, safety, and compatibility risks, which may cause harm or danger to the device.

Main differences:

Standard compliance: Standard power adapters comply with specific electrical and mechanical standards, while non-standard adapters ignore these standards.

Compatibility: Standard adapters can be universal across devices that meet the same standards, while non-standard adapters may only be applicable to specific devices.

Security: Due to strict adherence to standards, standard adapters are more likely to ensure safe use. Non standard adapters may pose risks as they have not undergone the same rigorous testing and certification.

Market availability: Standard adapters are usually easier to obtain in the market because they meet widely accepted standards. Non standard adapters may be more difficult to find or require purchasing through informal channels.

In summary, standard power adapters adhere to industry standards, ensuring safety and compatibility, while non-standard power adapters may involve certain risks and limitations. When purchasing a power adapter, choosing products that meet standard specifications is a more reliable and safer choice.
