Customer Pain Points
As device power requirements increase, traditional USB-C cable systems face significant limitations:
Insufficient power capacity for modern devices
Many cables still max out at 60W or 100W, unable to support high-performance laptops and workstations requiring 140W–240W charging.
Unstable performance under high current load
Poor conductor design leads to heat buildup, voltage drop, and unstable charging under sustained high power output.
Lack of PD 3.1 EPR compatibility
Many suppliers do not support Extended Power Range (EPR), making products incompatible with next-generation USB-C PD 3.1 ecosystems.
Inconsistent quality in high-wattage cables
Without proper shielding, E-Marker chips, and copper core optimization, cables degrade quickly under heavy load conditions.
OEM customization bottlenecks
Brands struggle to find suppliers capable of combining high-wattage engineering with branding, packaging, and scalable production.
