TORRAS 67W Retractable GaN Charger Review: The Ultimate Ultra Thin Charger and Slim Charger for Multi-Device Fast Charging

Unboxing the TORRAS 67W Retractable GaN Charger
The TORRAS 67W Retractable GaN Charger arrives in minimalist packaging that highlights its key features: a built-in cable, 67W output, and compact form. Inside, you’ll find just the charger and a user manual—no excess clutter. Right away, it’s clear this is designed as an ultra thin charger for modern travelers. Its sleek blue shell and magnetic cable dock signal a premium experience, setting it apart from generic adapters. As a slim charger, it promises both portability and power, a balance many struggle to achieve.

Sleek Aesthetics and Thoughtful Details
Featuring a glossy blue finish with rounded edges, this ultra thin charger feels solid yet lightweight in hand. The TORRAS logo is subtly embossed on both sides, while technical specs are cleanly printed near the input. It includes foldable Chinese standard pins and a 102cm flat retractable USB-C cable that resists tangling—a smart touch for any slim charger. The magnetic storage slot neatly secures the cable tip, enhancing both aesthetics and portability. This level of refinement is what users expect from a high-end ultra thin charger.

Comprehensive Fast Charging Protocol Support
This slim charger supports QC3.0/4+, SCP, PD3.0, PPS, and more. Both the fixed USB-C port and the retractable cable deliver five fixed PDOs (5V3A to 20V3.35A) plus a 5–11V4A PPS range. With a dual-output strategy of 45W + 20W, it can charge a laptop and phone simultaneously—ideal for multi-device users. Such versatility is rare in an ultra thin charger, making it far more capable than its size suggests. Whether you’re using it as a desk companion or travel essential, this slim charger adapts seamlessly.

Compact Dimensions and Lightweight Build
Measuring just 72.58 × 58.09 × 33.76 mm and weighing only 143g, this ultra thin charger is noticeably smaller than Apple’s 67W model. Its pocket-friendly footprint makes it perfect for backpacks, briefcases, or even jacket pockets. Despite its tiny stature, it never compromises on output—proof that today’s best slim charger designs prioritize efficiency over bulk. For frequent flyers, this ultra thin charger eliminates the need for multiple adapters.

Robust Safety Certifications and Internal Architecture
Certified with CCC and Level VI energy efficiency, this slim charger meets global safety standards. Internally, the PCB uses a recessed transformer layout to save space, while high-voltage electrolytic capacitors are wrapped in insulating sleeves. Both board sides are filled with thermal compound to manage heat during extended use—critical for any reliable ultra thin charger. These design choices ensure long-term durability without sacrificing the slim charger’s compact profile.

Primary-Side Power Management with Integrated GaN
At the heart of this ultra thin charger lies the HYC3657 chip from Huayuan ZhiXin—an integrated GaN solution with a 700V enhancement-mode transistor. It enables multi-mode operation (QR, DCM, PFM) with <20mW standby power, a hallmark of advanced slim charger engineering. Supporting components include a Bluebao fuse, KinTin X2 capacitor, and ChuangHui filter capacitors, all working in harmony to create a stable, efficient input stage within this ultra thin charger.

Secondary-Side Efficiency and Voltage Regulation
The secondary side features Southchip’s SC3503 synchronous rectifier controller driving V-Semiconductor’s VSP004N10MS-G MOSFETs (3.8mΩ). Paired with 25V/330μF solid-state capacitors, it ensures clean, efficient power delivery. A second-stage SC8724 buck-boost converter maintains precise voltage at the retractable cable end—essential for consistent fast charging. This layered approach is what allows this slim charger to perform like much larger units. No other ultra thin charger integrates such refined power staging in this form factor.

Intelligent Protocol Control and Multi-Port Safety
Protocol negotiation is handled by Injoinic’s IP2738U, supporting dual-port PD3.1, PPS, and UFCS. Three VBUS switches (two Xinfeihong FH8906G6 and one AOS AON7544) enable dynamic load sharing and robust over-current protection. This intelligent system ensures that whether you’re using it as an ultra thin charger for your ultrabook or a slim charger for your smartphone, every connection is safe and optimized. In a market flooded with basic adapters, this ultra thin charger stands out through intelligence—not just size. And for users demanding reliability without bulk, this slim charger delivers where it matters most.
