Abstract
Description
Technical Field
[0001] This utility model belongs to the field of charger technology, specifically relating to a portable super-fast charger. Background Technology
[0002] Chargers can be classified into low-frequency chargers and high-frequency chargers based on the operating frequency of their circuit design. Low-frequency chargers are designed based on traditional analog circuit principles. The internal power components (such as transformers, inductors, and capacitors) are relatively large. They generally produce relatively low noise when operating under heavy loads. However, this type of charger has stronger resistance to harsh power grid environments, and its reliability and stability are better than those of high-frequency chargers.
[0003] Existing fast chargers, due to their single output port and low power, cannot meet the needs of rapid charging of multiple devices simultaneously. Furthermore, the different shapes and structures of socket holes in different countries or regions still cause many inconveniences when using such electrical appliances in different areas. Many existing power adapters have plugs that are fixed to the outer casing. This structure means that a power adapter can only be plugged into one type of socket, which can only meet the safety regulations of a specific area. Different power adapters are required in different countries, causing inconvenience to users who are on business trips or traveling abroad. Utility Model Content
