recent, Apple's official website off the 29W USB-C power adapter, replaced with a 30W USB-C product that adds 1W power.
Apple's new 30W adapter has been upgraded, and the output configuration has 4 voltage positions. The specific specifications are 5V/3A, 9V/3A, 15V/2A, 20V/1.5A; while the previous 29W adapter has only two gear positions. Specifications are 5.2V/2.4A, 14.5V/2.0A, originally equipped for 12-inch MacBook, so the voltage of 14.5V is unique.
The current USB PD fast charge has been quite popular, and Apple's compliance with the trend to do some small upgrades is also reasonable. Apple's products have always been known for the use of materials and workmanship.
But to say more, still have to be removed, look at what features this charger has. First, Apple 30W USB PD charger appearance
The product logo is printed on the outer packaging, which is not different from the previous 29W.
USB-C 30W charger in various languages, can be used to charge notebooks.
This side is written with 'compatible USB-C device, recommended for MacBook'.
The other side is the detailed input and output parameters, model number is A1882, the output gear position is 5V/9V/15V/20V, which has a 9V and 20V gear position than the previous 29W adapter, but the 12V voltage position is increased. 5V and 9V are available. To adapt to the phone, 15V and 20V can be adapted to the laptop.
Open the package. The accessory has a product manual, warranty card.
2. The national standard conversion head pin is still a foldable design.

Compare size with 87W Apple Charger.
From left to right, Apple 87W, ANKER dual port USB-C charger, millet 45W, Apple 30W.
The conversion plug is unplugged, and the charger conversion head foundry is Weiwei Technology.
There is a serial number in the pin, which can be used to distinguish whether the charger is genuine or not.
The width is about 66.24mm.
The length is about 66.06mm.
The thickness is about 38.64mm.
The weight is about 106.3g, a very heavy charger.
Supported voltage gears were detected using ChargerLab POWER-Z FL001S, 5V/3A, 9V/3A, 15V/2A, 20V/1.5A four-speed voltage, consistent with the nominal.

Filled with Huawei P20 PRO, the power is about 14.8W.
Full Han 30W PD charging treasure, power 23.8W.
Filled with purple rice No. 10, the power is about 30W.
Charge New MacBook, power is about 27W. Second, Apple 30W USB PD charger dismantling
Violently open the outer shell.
Full-area copper-clad, enhanced heat dissipation, and glue inside the casing to help with heat conduction. This heat dissipation configuration is generally only seen on high-power notebook power supplies.
Firewire, neutral, ground.
The ground wire is fixed inside the Torx screw.
Black insulating tape.
The copper piece is completely wrapped.
Tear open the heat shrinkable tube, close the wire solder joint, pass through the hole, and solder firmly.
The copper piece is taken out.
The internal circuit is designed with two PCBs and is fixed by a plastic case. The primary circuit board is covered with a plastic cover and insulated support.
Secondary rectified output circuit.
USB-C output plug-in, two capacitors in parallel for output filtering.
The firewire pins are protected by heat-shrink tubing. The insulating sheets are slotted on the fuse pins and glued to the pins.
Here, the two wires are also fixed on the internal insulation with glue, and the process is exquisite.
2. Separate the insulation spacer between the two boards.
Two 35V 33μF ruby capacitors and a daily chemical KXJ electrolytic capacitor, with a withstand voltage of 400V 39μF, a Y capacitor in the middle, also has an insulator.
This angle can be seen in the input common mode inductor, fuse, varistor.
Japan's Black King Kong KXJ series of 400V 39μF input filter electrolytic capacitor, the transformer is Sumida OEM.
The fuse has a cable on one side of the capacitor connected to the output circuit board. Compared with the traditional charger, there is a film capacitor inside, which will be mentioned below.
Y capacitor close-up.
On the back of the board, this power supply is inconsistent with our common power architecture and is an LLC resonant structure.
The FLUT12A2060 is the primary control IC of Infineon Infineon, a custom model, packaged in PG-DSO-12. Thanks to the LLC architecture, there are two Infineon switches.
Infineon Infineon IPL65R1K5C6S details.
IPL65R650C6S, both belong to Infineon CoolMOS C6 series. Two tubes form a half bridge, transformer windings and film capacitors are connected in series to form LLC architecture.
USB-C small board front, you can see that the other board's cable is connected to the optocoupler.
Continue to see the components in the middle of the capacitor.
ON Semiconductor synchronous rectifier controller, there is no such model in the product list, it is a custom model.
Anson FDMS86201 synchronous rectifier, here the PCB is immersed in gold. 120V withstand voltage, 49A, 11.5mΩ.
The back of the USB-C board is the Cypress USB PD protocol chip.
Close-up of Cypress protocol chip, silk screen for CYPD3135 for Cypress's USB PD protocol chip CCG3.
CCG3 is a highly integrated USB-C controller that complies with the latest USB-C and PD standards and is currently USB PD2.0 certified. CCG3 is a complete USB-C and USB power port control solution available For notebooks, monitors, docking stations and power adapters. CCG3 uses Cypress's proprietary M0S8 technology, with 32-bit, 48-MHz ARM Cortex-M0 processor, 128 KB flash, 8KB SRAM, 20GPIOS, full speed USB device controller. Cryptographic engine for authentication, 20V fault-tolerant regulator, and a pair of FET switch 5V (VCON) power supplies for powering the cable. CCG3 also integrates two pairs of gate drivers to control external VBUS FETs and system-level ESD Protection, power supply applications, CGG3 commonly used package 40-QFN, 32-QFN two package forms.
1014-418 is an optocoupler that communicates with the PWM controller to regulate the output voltage and overcurrent protection. The lower right corner is the VBUS switch and the current sense resistor.
The charger is internally installed with 6 sets of insulated molds, which is unprecedented in the charger.

Summary of the charging head network disassembly As the most complete USB PD charger in Apple's history, the material of this 30W USB PD charger naturally has nothing to say, we also have to admire Apple's design and manufacturing standards, multiple places Details highlight the craft technology.
Internal use of all Japanese high-quality capacitors, Infineon and ON Semiconductor's semiconductor components, the addition of the LLC architecture , can improve conversion efficiency and reduce fever.
In addition, in the new charger of Apple, a Cypress Cypress CCG3 (CYPD3135) protocol chip is used. This material is not only compatible with multiple protocols, but also supports data encryption. This is the Apple 30W charger capable of supporting four. The main reason for the output voltage is also the biggest upgrade of the original 29W charger.
