Unverified功率越高发热越明显：65W以上充电头和充电宝在快充时温度可达45度以上，会触发降速保护，实际持续功率往往低于标称峰值87% similarUnverified有线快充功率超过90W后边际收益递减，从65W到100W通常只快10分钟以内，但发热和电池损耗明显增加，日常一晚上充电场景下65W已完全够用85% similarUnverified快充功率与发热正相关，充电越快电芯温度越高、循环寿命略降；多数场景30W快充与65W实际充满时间差距有限，非急用不必盲目追高功率83% similarUnverifiedUSB充电式护具的加热速度取决于功率，10-15W可在3-5分钟升温到设定值，功率过低（<8W）在冬季升温慢且难维持温度82% similarUnverified加热功率越大加热越快但便携性越差：车载12V款功率仅约100W需40分钟以上；家用220V款300W左右约20分钟；追求速热选220V直热，追求随处可用选双电压款81% similar
