Description

Technical Field

[0001] This application relates to the technical field, and more particularly to a portable charging device. Background Technology

[0002] With the maturity of wireless charging technology and solutions, wireless charging is increasingly becoming a power supply method for various electronic appliances. Many electronic products, such as smartwatches, now only support wireless charging and no longer support wired charging. However, wired charging remains the primary charging method and is preferred by many appliance users. Therefore, an all-in-one charger has emerged, integrating both wireless charging and wired output.

[0003] Currently, the portable chargers available on the market that combine wireless and wired outputs mainly come in the following product forms:

[0004] 1. The product consists of an input cable, a middle card board (split board), a wireless charging pad, and a wired output cable. The circuitry is typically distributed across the middle card board (split board) and the wireless charging pad. The middle card board usually handles voltage division, power distribution, and other functions. Sometimes, the wireless charging circuitry is integrated into the middle card board. Since wired outputs have various interface types, this product design typically achieves compatibility with different interface specifications by changing the output interface of the wired output terminal or using an adapter.

[0005] 2. The product consists of an input cable, a wireless charging pad, and a wired output cable. Compared to product 1, this product combines the wireless charging pad and the central card board into one, making the product more streamlined. Compatibility with different output interface types can be achieved by changing the output interface type of the output cable or by using an adapter.

[0006] 3. The product consists of a main body with two interfaces (male or female), typically combined as a male (A) and female (C) connector. The male (A) connector is usually used for input, while the female (C) connector can be used for both input and output. When used for output, it becomes a two-in-one product. Different cables can be used for output, compatible with various interface types. For example, connecting a CC cable supports C-port output, and connecting a C-Lightning cable supports Lightning port output.

[0007] These products typically have the following defects:

[0008] Both products 1 and 2 have relatively long cables, making them inconvenient to carry. Furthermore, the use of different cables during product manufacturing to support different interfaces or external adapters adds inconvenience to users.

[0009] Product 3 uses USB-A input, therefore its output does not support PD fast charging. As the most widely used fast charging standard, wired charging products that support PD can already support output power of 20V 5A (100W) or higher, which clearly cannot meet the current demand from users for ever-increasing charging power. Furthermore, because the built-in USB-A connector is close to the casing, while it appears to have a built-in input method, it is actually inconvenient to use.

[0010] All of the above products have fixed input and output directions, which further reduces the user experience. Utility Model Content
