Tips：

1. It is necessary to provide a dedicated PD fast charging charger for the computer. It is not allowed to use a power bank or mobile phone charger to charge the laptop, as the power usually cannot reach 100W and 20V, resulting in abnormal charging. The output power of the power adapter must match the power of the laptop, and it is best to use the original laptop charger

2.Some laptops need specific interfaces, such as For Dell/HP/thinkpad. They have specific models in the link. Please place an order according to your needs. Other ordinary models can be purchased in non-specific models

3.Some people may misunderstand that the 5A and 20V parameters in the link are inherent in the product itself, but in reality, they are not
For the 5A 20V described in the link, it refers to working in a 5A 20V environment. The connected device cannot exceed this parameter, rather than the product itself with 5A 20V. It is not possible to directly use a multimeter to test its voltage, which is an incorrect testing method

4.The style images of For Dell/HP/thinkpad marked in this link belong to the dedicated version, while the others belong to the universal version. The characteristic of the universal version is that the interface length is slightly longer because it needs to be compatible with more interfaces. If your laptop interface is relatively shallow, then after installation, a portion of the interface length will be left. If you mind, please do not place an order.
