Belkin 67W GaN Charger Teardown: Compact Powerhouse with Dual USB-C Ports

Product Overview and Core Advantages

This teardown focuses on the renowned brand Belkin's 67W GaN charger, a product that precisely meets users' dual demands for high power and portability. As a premium 65W USB C charger with dual USB-C ports, its core advantages center on the dual USB-C interface configuration—not only supporting 67W blind plugging for full power output without distinguishing ports, but also featuring a 45W + 20W dual-port simultaneous fast charging strategy.

Comparison and Technical Highlights

Compared to the brand's previously disassembled 100W model, this c pin charger retains full laptop charging capability and dual-device synchronous fast charging while significantly reducing body size, making it more suitable for daily commuting and travel. Notably, the charger adopts a zero standby power consumption energy-saving solution, incorporating advanced GaN power devices. As a high-quality 65W USB C charger, it offers higher efficiency conversion than traditional silicon-based power supplies, effectively reducing heat generation and improving long-term system reliability, while successfully passing CCC certification and Level VI energy efficiency certification.

Unboxing and Exterior Design

Upon unboxing, the product continues Belkin's classic charger design language with a minimalist overall style, only silk-screening core parameters on the back of the body. The model is WCH020yz, with input supporting 100-240V wide voltage. Single-port output covers fixed gears from 5V3A to 20V3.35A, plus two PPS gears. It features new national standard semi-encapsulated glue foldable pins. Measured dimensions are approximately 49.92 × 37.99 × 41.58mm, weighing 112g—a standout c pin charger with significant volume advantages compared to Apple's 67W charger.

Protocol Testing and Packaging Details

Tested with ChargerLAB POWER-Z KM003C, both USB-C ports fully support PD3.0, PPS, QC5, and other protocols with identical PDO messages, delivering a true blind-plug experience. The packaging maintains Belkin's minimalist brand style, with the front clearly displaying the Belkin logo, product name, appearance diagram, and core selling points. The back details the port power allocation strategy and features overview. Inside, it includes the charger host, user manual, warranty card, and hazardous substance list.

Output Specifications and Portability Features

As an efficient 65W USB C charger, the device follows the brand's series classic design, with no excess decoration. Input supports 100-240V wide voltage (50/60Hz 2A), adaptable to most global grids. Single-port output includes five fixed gears: 5V3A, 9V3A, 12V3A, 15V3A, 20V3.35A, plus 5-11V4.5A and 5-21V3.15A PPS gears for strong compatibility. Equipped with foldable pins that fully conform to the body when retracted, enhancing portability.

Internal Disassembly and Build Quality

During disassembly, opening the input end housing reveals pins fixed with plastic board and screws for insulation, with connection wires glued for protection. The extracted PCBA module uses a multi-small-board stacked design, with extensive gluing for reinforcement and heat dissipation. The top housing inner side has graphite heat dissipation stickers; measured module size ~41.21 × 32.8 × 35.64mm. As a compact c pin charger, it maximizes internal space efficiently.

Component Layout and Safety Features

After cleaning glue, the front shows three small boards forming independent zones with orderly core devices like capacitors and transformer, Mylar isolation between primary/secondary per safety standards. The front small board welds 3.15A 250V delay fuse, NTC thermistor, common-mode inductor, and rectifier bridge. Main board back features SMD Y capacitors and optocouplers.

Summary and Final Thoughts

Overall, Belkin's 67W GaN charger balances portability and practicality. Foldable pins and compact stacked PCBA drastically reduce volume, while GaN devices, comprehensive protocol support, and robust insulation/heat designs ensure output stability and safety. Whether single-port full-speed laptop charging or dual-port simultaneous phone/tablet fast charging, it handles effortlessly—a top choice among compact high-power chargers like this reliable 65W USB C charger. In summary, it achieves outstanding balance in design, performance, and safety, embodying Belkin's deep expertise in power devices.
