Detailed Teardown of llano 67W Retractable Cable GaN Charger: The Ultimate USB C Wall Charger Solution

1. Introduction to the llano 67W Retractable Innovation

The modern digital landscape in 2026 demands more than just raw power; it requires convenience and clutter-free solutions. The llano 67W Retractable Cable GaN Charger enters the market as a sophisticated usb c wall charger designed to simplify the charging experience. By integrating a 65cm retractable cable directly into a compact GaN power brick, llano has eliminated the common pain point of tangled or forgotten cables. This device is not merely a 65 watt charger (with a slightly boosted 67W peak); it is a versatile hub that caters to the high-performance needs of laptops and the rapid-charging requirements of smartphones simultaneously.

2. Unboxing and Aesthetic Design

Upon first glance, the charger features a cuboid design with rounded edges, finished in a matte texture that effectively resists fingerprints. The front panel houses a fixed USB-C retractable cable alongside a standard 1A1C port configuration. The retractable head is accented with a sleek silver coating and a lightning logo, symbolizing its fast-charging capabilities. The top surface displays the llano branding, while the bottom lists comprehensive technical specifications, including its 100-240V wide-voltage support, making it an ideal companion for international travel.

3. Technical Specifications and Power Distribution

The model ZD-AF65CN001 is a powerhouse in a small frame. Its output capabilities are tailored for 2026's tech ecosystem:

Single Port Output: Both the retractable cable and the independent USB-C port can deliver up to 67W (20V 3.35A), meeting the criteria for a high-end usb c wall charger.

USB-A Output: Supports 18W QC and 22.5W SCP for legacy devices or low-power accessories.

Multi-Port Logic: When multiple ports are used, the charger intelligently distributes power (e.g., 45W + 20W), ensuring that even while charging a phone, your laptop continues to receive significant power.

4. Advanced Protocol Support for Universal Compatibility

Using the ChargerLAB POWER-Z KM003C, we confirmed that this micro usb charger alternative (via its modern USB-C interface) supports a vast array of protocols: PD3.0, PPS, QC4+, FCP, SCP, and AFC. Specifically, it offers five fixed PDOs (5V3A, 9V3A, 12V3A, 15V3A, 20V3.35A) and a PPS range of 3.3-21V 3A. This level of compatibility ensures that whether you are charging a high-end MacBook, a Samsung Galaxy, or a Huawei flagship, the device communicates perfectly with the charger to optimize energy transfer.

5. Teardown: Exploring the Internal PCBA and Cable Module

Opening the shell reveals a high-density internal layout. The retractable cable module and the main PCBA (Printed Circuit Board Assembly) are connected via a plug-and-play interface, which streamlines the manufacturing process and enhances reliability. The interior is heavily protected by thermal silica gel and aerogel pads—materials known for their exceptional insulation and heat dissipation properties. This ensures that the 65 watt charger remains cool even during prolonged high-power output sessions.

6. The Heart of the Power: Joulwatt GaN Integration

The core of the power conversion is the Joulwatt JW1565J GaN-on-Si integrated chip. This highly advanced controller combines a high-frequency GaN driver with a 165mΩ GaN power transistor in a single VDFN6*8-8L package. By minimizing parasitic inductance, this chip allows for higher switching frequencies, which directly translates to the charger's reduced physical footprint. The JW1565J also features built-in X-capacitor discharge and high-voltage startup, making it one of the most efficient solutions for modern usb c wall charger designs.

7. Intelligent Protocol Management via Injoinic Chips

To manage the complex power delivery across three different outputs, llano utilizes Injoinic's industry-leading protocol ICs. The retractable cable is controlled by the IP2723T, which is USB-IF certified (TID: 3135) and supports nearly every fast-charging standard available. The USB-C and USB-A ports on the chassis are managed by the IP2726, a highly integrated IC that reduces the need for external components, thereby lowering the BOM cost while maintaining premium performance. This dual-chip setup ensures that the 65 watt charger can handle cross-protocol device handshakes flawlessly.

8. High-Quality Components for Long-Term Reliability

Reliability is bolstered by the selection of high-grade passive components. The high-voltage filtering stage employs four KT (Kaite) electrolytic capacitors (400V 27μF each), providing a stable reservoir for the primary circuit. The secondary side uses solid-state capacitors for low-ripple output. Furthermore, the inclusion of a Blue Diamond 3.15A fuse, NTC thermistors for inrush current protection, and common-mode chokes for EMI filtering ensures that this usb c wall charger meets rigorous safety standards like China's CCC.

9. Efficiency and Thermal Management Strategy

Efficiency in 2026 is synonymous with thermal control. The use of a synchronous rectification controller (Joulwatt JW7726B) instead of traditional diodes significantly reduces energy loss at the output stage. Combined with the NDP13701QB synchronous step-down converters for the multi-port power distribution, the charger maintains an energy conversion efficiency of over 92%. The aerogel insulation acts as a thermal barrier, preventing "hot spots" on the outer casing, which is a common complaint among cheaper micro usb charger adapters.

10. Practical Use: A Traveler’s Perspective

Weighing approximately 152g and featuring foldable prongs, the llano 67W charger is the epitome of portability. The 65cm retractable cable is long enough for most desk setups and bedside tables. In our testing, it successfully charged a MacBook Pro 14-inch from 0% to 50% in just 30 minutes. Its ability to replace a bulky laptop brick and multiple phone chargers makes it a mandatory inclusion in any modern tech kit. The mechanical retraction system feels robust, rated for thousands of cycles, ensuring that the cable remains a reliable part of the package for years.

11. Market Comparison and Value Proposition

When compared to standard 65 watt charger models from competitors, llano differentiates itself through the "all-in-one" retractable design. While some might prefer a detachable cable for maximum length flexibility, the convenience of never having to look for a cord is a significant value add. As more devices move toward USB-C, the demand for high-quality usb c wall charger solutions that offer both power and portability will only increase. Llano has positioned itself at the forefront of this trend with a product that is technically sound and user-centric.

12. Final Verdict: A Gold Standard for 2026 Charging

The llano 67W Retractable Cable GaN Charger is a masterclass in modern power electronics. It successfully integrates flagship GaN technology with a clever mechanical solution to cable management. With its wide protocol support, robust safety features, and high power density, it stands out as a top-tier usb c wall charger. Whether you are a business professional on the move or a student with a cluttered desk, this 65 watt charger offers the performance and neatness required in today's fast-paced environment. It is a reliable, efficient, and innovative choice that sets a high bar for the industry.
