[0036] A portable PD100W fast charger, such as Figure 1-Figure 3 As shown, it includes a fast charging seat 10 with a maximum output power of 100W, a heat dissipation through-hole 20 is opened on the top of the fast charging seat 10, and a winding groove 30 for winding the power cord is installed on the outer wall edge of the fast charging seat 10; two groups of charging A ports 11 and two groups of charging C ports 12 are installed at one end of the fast charging seat 10, and an input power cord 13 is installed on the side of the fast charging seat 10 away from the charging port; a cooling fan 22 is installed in the heat dissipation through-hole 20, and by installing two groups of charging A ports 11 and two groups of charging C ports 12 at one end of the fast charging seat 10, the charging needs of different devices are met. The charging A port 11 is suitable for some devices that require a larger current, while the charging C port 12 is suitable for Most modern electronic devices make the fast charging stand have a wider range of applicability. The winding groove 30 is installed on the outer wall edge of the fast charging stand 10, which is convenient for users to store and organize the power cord, avoids the situation of the power cord being messy, and improves the convenience of use. At the same time, the design of the winding groove 30 also makes the power cord not easily damaged during carrying, thereby extending the service life of the fast charging stand. The heat dissipation hole 20 opened on the top of the fast charging stand 10 is not only conducive to the discharge of heat, but also ensures that the fast charging stand will not overheat when working at high load for a long time. With the installed cooling fan 22, the heat dissipation efficiency can be further improved to ensure that a low operating temperature can be maintained even at high power output.

[0037] like Figure 4-Figure 8As shown, it is the circuit schematic diagram of the internal control board of the PD100W fast charging. The two sets of charging A ports 11 and the two sets of charging C ports 12 all use charging heads with fast charging protocol. The output of charging A port 11 is 5V3A, 9V2A or 12V1.5A, and the output of charging C port 12 is 5V3A, 9V3A, 15V3A or 20V5A.

[0038] Furthermore, the input power cord 13 adopts a car charger head or an AC-DC power adapter plug, the car charger head adopts 12-24v-PD-USB, and the AC-DC power adapter plug adopts 12-24v to provide PD-USB. The input power cord 13 adopts the design of a car charger head or an AC-DC power adapter plug, so that the fast charging stand can not only be used in fixed places such as homes or offices, but also can be easily connected to the vehicle power supply to meet the charging needs of users in mobile scenarios. The car charger head adopts a 12-24v-PD-USB design, which is compatible with the power systems of most vehicles and provides stable power output. The AC-DC power adapter plug also adopts 12-24v to provide PD-USB, ensuring the stable operation of the charging stand in various voltage environments.

[0039] Specifically, the input end of the cooling fan 22 is connected to the internal control circuit board, and the rated voltage of the cooling fan 22 is 12-24V. The input end of the cooling fan 22 is connected to the internal control circuit board, thereby realizing intelligent control of the fan.

[0040] Among them, a dustproof net 21 is arranged on the surface of the heat dissipation hole 20, which can effectively prevent dust and debris from entering the inside of the fast charging seat, avoid the blockage of the heat dissipation hole, and extend the service life of the fast charging seat.

[0041] It is worth noting that the cross-section of the winding groove 30 is arc-shaped and is engaged with the input power line 13, so that the power line can fit tightly in the winding groove and is not easy to fall off or move.

[0042] In addition, a charging display light 40 corresponding to the positions of two groups of charging A ports 11 and two groups of charging C ports 12 is installed on the top of the fast charging stand 10 near the charging port, so that the user can understand the charging status at any time and adjust the charging strategy or deal with charging problems in time.

[0043] The working principle of this portable PD100W fast charger: the operator connects the input power cord 13 to the corresponding interface of the fast charging seat 10 to ensure a firm connection, and inserts the other end of the input power cord 13 into a power socket to power the fast charging seat 10. When the fast charging seat 10 is working, the cooling fan 22 will automatically start and discharge the heat inside the fast charging seat through the heat dissipation hole 20. If the fast charging seat works at high load for a long time, you can pay attention to whether there is hot air discharged from the heat dissipation hole 20 to ensure normal heat dissipation. Avoid using the fast charging seat in a closed or high-temperature environment to maintain a good heat dissipation effect. After use, unplug the input power cord 13, disconnect the power supply of the fast charging seat 10, and wind the power cord back into the winding groove 30 to ensure neatness and easy carrying.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
