Disassembly report: satechi 100W 2c1a Gan fast charging charger
Recently, the charging head network got a 100W Gan fast charging charger from satechi, which has its own power cable and 2c1a interface. Both usb-c ports support 100W PD fast charging, and the single port output performance is exactly the same. It can be used blindly. As a desktop charger, it is convenient for users to charge daily. In addition, it also supports 60W + 30W dual port charging strategy. Let's disassemble this charger in detail and take a look at the internal design materials.
1、 Appearance of satechi 100W Gan charger
Satechi 100W Gan charger comes with a power line, and the line body is designed separately, so the power line of corresponding specifications can be replaced according to different regions, and the external use is more convenient.
The power cord is bundled with magic tie. The plug pin is American Standard. Both ends of the cable are treated with bending resistance, and this end is provided with a convex tooth, which is convenient for plugging. In addition, the cable specification is 7a 125V and has passed UL certification.
The length of the whole power cord is about 123cm.
The main body of this Gan charger is gray, the body is flat, the surface is frosted, the corners are rounded, and the top surface is printed with satechi brand.
The bottom four ends are provided with rubber pads to prevent slipping.
The charger parameters are marked on the side
Input: 100-240V ~ 50 / 60Hz 2A
Dual port output (C1 + C2)
Three port output: 60W + 30W + 12W
The input end adopts 8-type interface, and the product has passed the certification of ETL, FCC, CE, PSE and RoHS.
The output end adopts black shell, equipped with LED indicator and 2c1a interface. The black rubber core of usb-c port does not expose copper, and the blue rubber core of usb-a port.
The length of fuselage measured by vernier caliper is 95.41mm.
The width is 66.01mm.
Compared with apple 96w charger, it is longer and narrower.
The intuitive feeling of holding it in the hand.
The net weight of the charger is about 318g. The total weight of the belt is about 384g.

Summary of dismantling charging head net
Satechi 100W Gan fast charging charger has a flat body and round corners. It is equipped with a power cord and adopts a wire body separation design. At the same time, it supports a wide range of voltage input all over the world. It can be used in a wide range of areas. It can be carried to all places by replacing the power cord. The two C ports not only support 100W PD fast charging, but also have 5A PPS voltage range. Usb-a port supports 12W output and can charge small devices.
Through the disassembly of charging head network, we know that as a 100W high-power charger, it is equipped with PFC boost circuit and controlled by PI pfs7628c; The switching power supply is composed of PI high integrated main control chip sc1936c and Cr micro synchronous rectifier; Two C-Port secondary buck output scheme is exactly the same.
The dual C ports adopt the Dexin eup3268b with the Weizhao and Taide MOS transistors for secondary voltage reduction, and the output voltage is controlled by the huinengtai protocol chip husb350; The usb-a port adopts British chip ip6503s for secondary step-down and 5V constant voltage output. The whole circuit board is wrapped by copper sheet, and heat conduction stickers are set on the front and back sides of the circuit board to conduct heat to the shell, so as to reduce the temperature rise. All internal components are fixed and filled with glue, stable and reliable.
