Unverified50% confidenceDecision RuleTime unknown

线缆需支持5A电流才能触发40W以上快充（如66W/100W），标注3A的线缆最高只能跑到36W左右；5A线通常内置E-Marker芯片，判断方法是看线材是否标注'5A'或'100W/240W'

Unverified线缆截面积决定载流能力，10A/2500W插线板导线应≥1.0mm²，16A/4000W应≥1.5mm²，可查线身印字（如3×1.0）；线材过细是虚标功率的重灾区80% similar Unverified雷电3/雷电4(40Gbps)线材通常有长度限制，被动线缆一般不超过0.8米，超过需主动线缆（内置芯片补偿）成本更高，长距离高速传输需注意此限制79% similar
