Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a dual-handle mobile power bank. Background Technology

[0002] A power bank is a hybrid of a charger and a backup battery, often used in outdoor environments for power supply. During use, power banks generate a significant amount of heat, making their internal heat dissipation structure crucial for compatibility with various electronic devices.

[0003] When a power bank is in operation, its internal electronic components generate heat. Currently, in order to ensure that the heated electronic components can dissipate heat in time, heat sinks are installed on the electronic components. However, the heat sinks are generally fixed on the substrate and can only dissipate heat for the electronic components on the substrate. They cannot effectively dissipate heat for the battery pack at the bottom. Moreover, the existing heat dissipation structures are often quite complex, which makes the internal structure of the power bank more crowded and affects the stability of the product.
