Usb-c single port output: 5V / 3a, 9V / 3a, 12V / 3a, 15V / 3a, 20V / 3A (60W max)

Usb-a single port output: 5V / 3a, 9V / 2a, 12V / 1.5A (18W max)

Dual port simultaneous output (63w max)

USB-C:5V/3A、9V/3A、12V/3A、15V/3A、20V/2.25A

USB-A:5V/3A、9V/2A、12V/1.5A

Manufacturer: Kunshan liantao Electronics Co., Ltd

The product has passed 3C certification and VI level energy efficiency certification. The output end is equipped with 1a1c two output interfaces, usb-a interface with white rubber core, usb-c interface with black rubber core without copper exposure, and the lower end of the interface is gravure printed with ifory.

The thickness is larger than the diameter of a dollar coin.

The net weight is about 164g. The output protocol of usb-a port is detected by using chargerlab power-z kt001. The display supports apple 2.4a and usb-dcp protocols, as well as qc2.0/3.0 and Samsung AFC fast charging protocols.

The output protocol of usb-c port is detected by using chargerlab power-z kt001, which shows that it supports usb-dcp protocol. In addition, no other protocol is detected.

The PDO message display of usb-c interface supports USB pd3.0 fast charging standard, and has five groups of fixed voltage gears: 5V / 3a, 9V / 3a, 12V / 3a, 15V / 3a and 20V / 3a.

2、 Disassembly of ifory 63w fast charging power adapter

The front shell of the charger is violently disassembled. There is a conical fixed column on the shell. The internal components of the charger are basically covered by metal heat sink. Glue is injected between the shell and the heat sink for fixing and auxiliary heat conduction. Insulating Marla tape is pasted on some parts of the heat sink for insulation protection.

The plastic block at the input end is fixed with a clip, and there are two protruding metal shrapnel at the lower end, which are used to contact with the PCB to achieve the effect of power transmission.

After taking out the PCB, you can see that there is a metal heat sink on the small PCB next to the usb-a interface motherboard. There is also an L-shaped heat sink on the back of PCB board, which is coated with glue to help heat conduction, and the edge is wrapped with Mala tape for insulation protection.

The metal sheet on the other side is separated, and a black insulating plastic sheet is pasted on the metal sheet, and a piece of white thermal conductive silica gel is pasted on the plastic sheet. There is also a metal plate between the input and output ends for isolation.

Li'e rt7880 is a USB type C power transmission (usb-c PD) and pulse width modulation buck boost controller with highly integrated functions and flexibility, which is suitable for the application of USB PD providers. The IC has an embedded arm Cortex-M0 microcontroller, which handles communication protocol, intelligent control of PWM converter, firmware based protection and various functions of customization. Can provide an excellent USB PD solution for a usb-pd vendor application with few external components and simple PCB layout.

According to the charging head network, the products that use Li Ke Technology chip include Huawei 40W Super Charge super fast charger, Huawei 65W USB PD charger, original 45W USB PD power adapter for Xiaomi notebook, Razer thundersnake 45W USB PD charger, vivo 33W flashcharge 2.0 fast charger, original 45W USB PD fast charger for Google pixelbook, original Nintendo switch charger, etc.

Summary of dismantling charging head net

The front and back of the 1a1c 63w fast charging charger is bright, the side body is frosted, the pins are flexible, foldable and easy to carry. Port a supports qc2.0/3.0 and Samsung AFC fast charging protocol, and supports maximum 18W fast charging output; The C port supports USB pd3.0 fast charging standard, and has five fixed voltage ranges of 5 / 9 / 12 / 15 / 20V, with a maximum output power of 60W. When the two ports are used at the same time, the output power of C port is still 45W, while the output of a port is not affected, 18W fast charging can still be carried out, and the total output is 63w, which can meet the daily fast charging demand.

We learned from the disassembly of charging head network that this charger uses chips from many famous manufacturers in the industry, such as Tongjia's PWM main control chip, Infineon's switch tube, MPs synchronous rectifier controller, Weiquan PD protocol chip wt6633p, and Lixi voltage regulator rt7880, and so on. The output of C port of charger is directly output after synchronous rectification by transformer, and the output of a port is output after voltage conversion by rt7880. Thanks to the use of voltage up and down circuit, the output voltage of a port is not limited by the output voltage of C port. In addition, the charger uses a large area of metal heat sink cover and a large number of glue injection heat conduction, the components are not only firmly fixed, but also the overall heat dissipation performance of the charger is very good.
