Why PD Matters for Your Brand
PD is the future. EU regulations now require USB-C for all electronic devices by 2026. As a B2B buyer, sourcing PD-certified products ensures regulatory compliance and broad device compatibility.
4. Safety & The E-Marker Chip Factor
Professional buyers understand that high-wattage PD requires more than just a powerful charger. Safety mechanisms are non-negotiable.
The 60W Cable Limit
USB-C cables without E-Marker chips are limited to 3A (60W). For anything above 60W, you must use cables with certified E-Marker chips. Using an under-rated cable with a 100W charger is a fire hazard.
- 60W maximum: Standard USB-C cable (3A, no E-Marker)
- 100W maximum: 5A cable with E-Marker required
- 240W maximum: EPR cable with E-Marker required
