This charger is a standout usb c pd charger, a high-performance alternative to a standard 65w charger, and a top-tier usb c phone charger, winning praise for its ultra-compact size and broad multi-protocol compatibility. Below, we’ll break down its design, build quality, and core performance with a full unboxing and teardown.

Unboxing & Teardown: Huawei 66W GaN USB C PD Charger

As a thoughtfully engineered usb c pd charger, this 66W model excels as both a reliable 65w charger and a user-friendly usb c phone charger, with strong performance across the board. Here is the full breakdown:

Unboxing: Design & Parameter Testing

(1) Exterior Design Details

Materials & Finish: The charger uses a white PC flame-retardant plastic casing, with a sleek high-gloss finish. The minimalist design and compact build align perfectly with the portability users expect from a usb c phone charger

Markings & Interfaces: One side of the body is printed with "66W" and "HUAWEI SuperCharge" branding; the output end features a single USB-C port -- the standard for a premium usb c pd charger -- with the HUAWEI logo printed nearby. The input end has fixed national-standard prongs, with full product specs for this 65w charger alternative printed on the casing

Dimensions & Weight

Measured size: 48.11mm long, 31.01mm wide, 31.03mm thick

Measured weight: ~70g

Competitive Edge: Compared to Apple's 67W usb c pd charger, this model is noticeably smaller and lighter in the hand, making this usb c phone charger far easier to carry daily

(2) Core Specs & Protocol Testing

Output (full voltage range): 5V3A, 9V3A, 10V4A, 11V6A, 12V3A, 15V3A, 20V3.25A Max (high-voltage input); 15V2.66A, 20V2A Max (low-voltage input)

Certification: CCC certified, a key safety guarantee for this usb c pd charger

Charging Protocols & Testing (Charger LAB POWER-Z KM003C)

Supported Protocols: UFCS, FCP, SCP, QC2.0/5, PD3.0, PPS, DCP -- a wide range that lets this 65w charger work with nearly all modern devices

PD3.0 Profiles: 5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A (fixed); 3.4-21V3.25A (PPS)

UFCS Fast Charging Profiles: 3.4-5.5V5A, 5.5-10V6.6A, 10-11V6A, 11-20V3.25A, 20-21V3.1A -- the flexible voltage options make this usb c phone charger more versatile for different devices

Teardown: Internal Structure & Components

(1) Teardown Process & Overall Structure

When we removed the top casing, we found the internal PCBA module is filled with white adhesive for reinforcement, boosting stability and heat dissipation to support long-term use of this usb c pd charger The PCBA module uses a contact-based power input design, covered with thermal conductive adhesive, an insulating plastic sheet, and a heat sink. The primary and secondary circuits are isolated by an integrated partition, a design that boosts the safety of this 65w chargerMeasured PCBA size: 44.44mm long, 26.64mm wide, 26.89mm thick -- the compact, organized layout is what allows this usb c phone charger to stay so small

(2) Core Component Breakdown

Input Small Board

Front: NTC thermistor (suppresses power-on inrush current), STE Matsuda Electronics safety X2 capacitor (0.1μF), common mode inductor (EMI filtering, covered with heat shrink tubing), 2 rectifier diodes

Back: 2 additional rectifier diodes, forming a bridge rectifier circuit that supports steady operation for this usb c pd charger

Main Board Core Components

Time-delay fuse: Better Electronics Model 936, 2A250V

High-voltage filter electrolytic capacitors: 2 Acon units, 400V27μF each

Switching power supply controller: Silkscreen LYW6561

Primary switch: Innoscience INN700DC240C (700V enhanced GaN switch, 240mΩ on-resistance, DFN5*6 package, built-in ESD protection) -- this high-quality component is what delivers the strong charging efficiency of this 65w charger

Other components: Controller power capacitor, safety Y capacitor, I-shaped filter inductor (covered with heat shrink tubing)

Secondary & Output End

Planar transformer: Independent small board design, with the magnetic core covered in an insulating plastic shell

Output filter: 2 solid-state filter capacitors, soldered to the USB-C port small board -- these ensure consistent, stable charging for this usb c phone charger

Isolation design: A black plastic shell separates the high-voltage filter capacitor and output board for extra electrical safety

Auxiliary Structures

Thermal Management & Fixing: The input end is sealed with thermal conductive adhesive, and the back of the main board is covered with an insulating plastic sheet and heat sink

Insulation Protection: The common mode inductor and I-shaped inductor are covered with heat shrink tubing, with an integrated partition for primary-secondary isolation -- all these features protect the internal components of this usb c pd charger
