In addition to providing the most powerful functions within the limited volume of electronic products, more and more attention is paid to the portability of electronic products. To get the assistance of electronic technology at any time to make life more convenient.

Continuing from the above, due to the emphasis on the portability of electronic products, various manufacturers have devoted themselves to studying the technology of miniaturization of electronic products, and have achieved quite fruitful results in a short period of time. However, electronic products also have inherent limitations, which on the other hand limit the rapid development of electronic technology. This innate limitation mainly comes from the power supply. When electronic products are used, they must rely on electric power to provide drive. When the power is insufficient or interrupted, even the most powerful electronic products are useless. Since traditional electronic products are mainly used in fixed places and rely on indoor power supply, the problem of power supply is often ignored in use. But for portable products, every milliampere of electricity is a very precious resource. Although various manufacturers are also working hard in the direction of low energy consumption, they are still unable to make effective breakthroughs due to the limitation of power storage technology. Therefore, under the limited battery space, there is often a temporary power interruption problem. Especially for electronic products that are getting smaller and smaller, their batteries are also reduced accordingly, making it more difficult to store electricity, thus limiting the use of portable electronic products.

For this reason, some people will carry chargers when they go out, but the size and shape of the chargers are not easy to store, and the chargers of each portable electronic product may not be compatible with each other. , Every time I go out, I have to carry some sundries, which is really inconvenient. Or someone will carry a backup power source such as a second battery or a small generator when they are out and about. However, these devices are not frequently used products, and they take up limited personal carrying space, so most people do not or are inconvenient to carry them with them. Even if they want to carry them, they may forget to carry them due to temporary haste, so their application rate is not high.

Please refer to FIG. 3A to FIG. 3I , the first and second input port 4a, 4b and the output port 4 are any data transmission ports that can achieve the charging function, and the output port 4 is now used for illustration. Currently common types are USB and IEEE 1394. The most common type of the USB port is the standard USB A Type with a rectangular flat shape (Figure 3A), or the standard USB B Type with a square shape (Figure 3B). And the mini USB A/B (Fig. 3C/D) and other port types that have been developed to reduce the size later, or the micro USBA/B (Fig. 3E/F) that is smaller in size and easy to apply to mobile devices, or the latest proposed USB3.0 A/B (Figure 3G/H) and other types. The type of IEEE 1394 began to distinguish between IEEE 1394a 6Pin (Figure 3I) and IEEE 1394a 4Pin (Figure 3J) specifications based on pin position, and later changed to IEEE 1394b 9Pin (Figure 3K) and other types as the transmission volume increased.
