Key Selling Points
5.0mm Thickened Cable Diameter Design
Adopts an industry-leading 5.0mm large cable diameter structure, providing ample internal space to effectively reduce resistance and heat generation.
Supports prolonged high-power transmission, with a temperature rise approximately 35% lower than standard cables during 60W full-load operation.
Full and sturdy cable body offers a substantial feel and stronger physical damage resistance.
High-Density Braided Reinforcement Process
96-strand high-density braided outer sheath provides excellent resistance to stretching, wear, and tangling.
The braided layer is treated for anti-static and water-splash resistance, adapting to various usage environments.
Features a fine, uniform surface texture that balances aesthetics and functionality.
Precision Aluminum Alloy Connectors
Connectors are made from 6063 aviation-grade aluminum alloy using CNC one-piece molding, with an anodized surface finish.
Gold-plated internal contacts ensure high conductivity, with a plug/unplug lifespan of ≥10,000 cycles.
Four-layer injection molding reinforcement at the junction between connectors and cable body effectively prevents breakage risks.
Intelligent Fast Charging with Full Compatibility
Automatically recognizes device types and intelligently matches mainstream fast-charging protocols such as PD3.0, QC4+, and AFC.
Supports fast charging and data transfer for various devices, including smartphones, tablets, and laptops.
Use Cases
Gaming phones and devices requiring high-current transmission.
Office and creative scenarios with long-term high-load usage.
Environments demanding high cable durability, such as car charging and power banks.
Professional users and enthusiasts seeking reliability and stable performance.
Technical Features
DC Resistance: <0.08Ω/m
Rated Current: 5A (Max)
Operating Temperature: -30°C to 70°C
Tensile Strength: ≥100N
Bend Life: ≥15,000 cycles
Usage Recommendations
For optimal 60W fast charging performance, use with a PD charger rated ≥65W.
When storing, avoid sharp-angle bends; using a cable winder with a diameter ≥8cm is recommended.
Regularly clean the metal contacts of the connectors to maintain good conductivity.
Avoid prolonged use in humid environments to prevent affecting internal insulation performance.
