Introduction
The 100W SuperVOOC, as a core fast-charging pillar for OnePlus smartphones, is now compatible with multiple models, including the OnePlus Ace series. This charger delivers 100W high-power output while achieving a lightweight design of approximately 112g. Next, we will proceed with a teardown to examine its components and structure.
Product Appearance
The front of the packaging features the OnePlus logo, the product name, and an image of the complete set.
A specification sticker is affixed to the back.
The package includes the charger, a cable, and a user manual.
The included cable is a USB-A to USB-C type, featuring a red cable body with a matte-finished connector housing.
The length of the cable is about 99 cm (38.98 inches).
The housing is made of flame-retardant PC material with a matte surface finish.
“100W SUPERVOOC” is printed on this side.
The input-side housing is printed with the specification information.
Model: VCBAOBCH

Input: 200–240V~50/60Hz 2.5A
Output: 5V 2A, 5–11V 9.1A MAX (100W MAX)
The charger is CCC certified.
It comes with fixed prongs.
The top is recessed, with a single USB-A port at the center.
The length of the charger is about 54.82 mm (2.16 inches).
The width is about 54.33 mm (2.14 inches).
The thickness is about 31.44 mm (1.24 inches).
Compared side by side with the Apple 96W charger, it is significantly smaller in size.
That's how big it is in the hand.
The weight is about 112 g (3.95 oz).
ChargerLAB POWER-Z KM003C shows that the USB-A port supports QC3.0, SVOOC, VOOC, and DCP charging protocols.
Using the charger set to charge the OnePlus Ace 5, the 100W SuperVOOC fast charging was successfully activated, with a charging power of about 75.89W.
Teardown
Next, let's take it apart to see its internal components and structure.
Open the input-side housing, and the prongs are connected using wires.
The length of the PCBA module is about 50.74 mm (2 inches).
The width is about 50.02 mm (1.97 inches).
The thickness is about 24.45 mm (0.96 inches).
The front of the PCBA module has the capacitor, transformer, and USB-A socket reinforced with adhesive, and a plastic isolation plate is installed between the primary and secondary sides.
The bottom is covered by a plastic panel and a heatsink.
After removing the plastic panel, all the core components on the back of the PCBA module are secured with adhesive.
The components on the front of the PCBA module are arranged compactly.
On the back, there is a master control chip, primary MOSFET, optocoupler, synchronous rectifier, protocol chip, and output VBUS MOSFET.
The time-delay fuse is from Betterfuse, rated at 3.15A 250V.
The NTC thermistor is from JOYIN, model 8S2R5M, used to suppress inrush current when the charger is powered on.

The safety X2 capacitor is from CARLI, with a capacitance of 0.22 μF.
The common mode choke is also covered with heat-shrink tubing for insulation protection and is used to filter EMI interference.
The bridge rectifier is from DiYi, model UG8KB100A, rated at 8A 1000V, and uses a D3K package.
The I-shaped inductor is insulated with heat-shrink tubing.
The high-voltage filter electrolytic capacitor is from Koshin, rated at 400V 33 μF.
The other one is from AiSHi.
It is rated at 400V 33 μF.
The third one is also from AiSHi.
It is rated at 400V 27 μF.
The capacitor supplying power to the master control chip is from Acon, rated at 100V 10 μF.
The master control chip is from SouthChip, model SC1835, and functions as a flyback controller.
The primary MOSFET is from Navitas, model NV6134C. It is a highly integrated gallium nitride (GaN) power device with a built-in driver and high-precision, lossless current-sensing circuit, eliminating the loss associated with sensing resistors. It features a 260 mΩ on-resistance, a 700 V-rated GaN FET, supports a 2 MHz switching frequency, and comes in a 6×8 mm QFN package, saving PCB space.

The synchronous rectifier controller is from SouthChip, model SC1836. It supports a 400 kHz switching frequency and operates in DCM, CCM, and QR modes. It can be used for both high-side and low-side applications and comes in a SOT23-6 package.
The SC1836 supports a wide output voltage range, with the output voltage capable of going as low as 0 V. It does not require an auxiliary winding for power, and its patented adaptive turn-on detection circuit prevents false conduction of the rectifier. The built-in driver is compatible with various MOSFETs, delivering high efficiency that meets CoCV5 and DoEVL energy efficiency standards.
Here is the information about SouthChip SC1836.
The synchronous rectifier is from PY, model PW028N06ESL. It is an NMOS with a voltage rating of 60 V, an on-resistance of 2.3 mΩ, and comes in a 5×6 mm DFN package.
The two solid capacitors are from BERYL, rated at 16 V 820 μF.
The protocol chip is from SouthChip, model SC1834.
The output VBUS MOSFET is marked 055N03L2 and comes in a 3×3 mm DFN package.
Well, those are all components of the OnePlus 100W SuperVOOC GaN Charger.
Summary of ChargerLAB
Here is the component list of the OnePlus 100W SuperVOOC GaN Charger for your convenience.
It is relatively compact in size. It supports OnePlus SUPERVOOC 100W proprietary fast charging, as well as QC3.0 and DCP fast charging, providing high-power charging for OnePlus phones while maintaining broad compatibility.
After taking it apart, we found that it uses a complete high-performance power solution consisting of the SouthChip SC1835, SC1836, and SC1834, paired with the Navitas NV6134C primary MOSFET. In addition, it employs capacitors from AiSHi, Koshin, and BERYL for filtering. Judging from the selection of core components, the materials are solid and reliable.
