Second, look at the rated capacity

In order to display the large capacity of the power bank, merchants usually mark the rechargeable battery capacity (such as 1000mA · h) in a conspicuous place, but during normal charging, the power bank’s output capacity cannot actually reach the battery capacity due to energy loss such as voltage conversion and heat generation.

The rated capacity is the effective discharge capacity of the power bank calibrated by the manufacturer. The higher the rated capacity, the more power the power bank can charge for the mobile phone!

III. See if the fast charging protocol matches

PD protocol refers to the USB-PD protocol. It is a fast charging protocol proposed by the USB-IF organization, which aims to provide high power transmission and faster charging speed. The fast charging protocol can be understood as a password between the mobile phone and the power bank. If both the mobile phone and the power bank support the PD protocol, it can be charged faster.
