Description

Technical Field

[0001] The utility model belongs to the technical field of power banks, and in particular relates to a magnetic building block type power bank. Background Art

[0002] A power bank, also known as a mobile power bank or portable charger, is a portable device that stores energy and is primarily used to charge handheld mobile devices and other consumer electronics (e.g., wireless phones and laptops). It is particularly useful in situations where an external power source is unavailable. Its main components include a battery for storing energy and a circuit (DC-DC converter) for stabilizing the output voltage. Most power banks also include a charger to charge the internal battery.

[0003] Currently, large-capacity power banks are often inconvenient to carry. To increase battery capacity, large-capacity power banks are often very thick. While this thickness itself isn't a problem, the main issue is that when such power banks are placed in a handbag or backpack, their space utilization is far from ideal. This creates a pain point where you can't flexibly choose a power bank based on your travel needs. Utility Model Content
