USB C headlamps are not only an extended external charging port for rechargeable headlamps, but also a USB interface standard commonly used by various electronic devices. With the rapid development of electronic equipment, the transmission rate of USB Micro can no longer meet the data transmission and charging needs of various devices. The fast charging protocol for charging has come to the era of USB 3.2, and the traditional USB Micro interface can no longer keep up with USB. The latest specification, so I think the USB C interface is the current development trend.
The reasons why the rechargeable headlamps are connected to the external USB C port are as follows: Thin and light headlamps are more and more popular. Smaller headlamps not only need better heat dissipation, but more importantly, they need to be thinner For the charging interface, the length of the USB C port is 0.83 cm, and the width is 0.26 cm. The length of the traditional USB micro port is 1.4 cm, and the width is 0.65 cm. This size does not meet the needs of most electronic devices. Secondly, the USB C port is like Apple’s Lightning interface, the front and back of the port are the same, which is the so-called hot-swappable design. Finally, the transmission rate of USB C reaches 10Gbit/s, and the charging power can reach 120 watts. However, the transmission speed of USB micro is only 480Mbps, and the maximum charging power is 5 watts. In this era of technology, fast charging is the mainstream demand, which is the main reason why we choose USB C headlamps.
