Description

Technical Field

[0001] The utility model relates to the technical field of portable power supplies, and more specifically, to a card-type ultra-thin power bank. Background Art

[0002] A power bank is a portable charger that can be carried around by individuals and stores electrical energy. It is primarily used to charge handheld mobile devices and other consumer electronics (e.g., wireless phones and laptops), and is particularly useful in situations where there is no external power supply. Its main components include a battery for storing electrical energy and a circuit for stabilizing the output voltage. Most power banks come with a charger to charge the internal battery. A card-type ultra-thin power bank is a lightweight, highly portable mobile power source. It is typically very thin, similar to a card, making it easy for users to carry around. Currently, card-type ultra-thin power banks generate significant heat during charging and discharging, which can affect the lifespan of the power bank over time. Utility Model Content
