What is the difference between power bank battery capacity and rated capacity?

The battery capacity and rated capacity of a power bank are two different concepts: 1. Battery capacity refers to the total charge stored in the power bank battery. A higher battery capacity means that the power bank can provide more Electric energy; 2. Rated capacity refers to the amount of charge that the power bank manufacturer claims to be able to actually output in the product specifications, and is determined based on the design and manufacturing standards of the power bank.

The battery capacity and rated capacity of the power bank are two different concepts:

1. Battery Capacity: Battery capacity refers to the total amount of power stored in the battery of the power bank. The amount of charge is usually expressed in milliamp-hours (mAh). A higher battery capacity means the power bank can provide more power, allowing for more recharges or longer use of the device.

2. Rated Capacity (Rated Capacity): Rated capacity refers to the amount of charge that the power bank manufacturer declares in the product specifications to be able to actually output, also expressed in milliampere hours (mAh) . The rated capacity is usually determined based on the design and manufacturing standards of the power bank. However, in actual use, due to factors such as the battery's internal resistance, line loss, and conversion efficiency, the actual amount of charge that can be output is often lower than the rated capacity.

Therefore, the battery capacity of a power bank refers to the total amount of charge actually stored in the power bank battery, while the rated capacity is the amount of charge that the manufacturer claims it can output. When purchasing a power bank, you can refer to the rated capacity as a reference indicator. However, in actual use, many factors must be taken into consideration, such as charging efficiency, line loss, etc., as well as the power requirements of the equipment used to determine whether the power bank can meet the required requirements. Charging needs.
