Unverified扩展电池充电协议需匹配手机快充协议才能高速回充自身（如支持PD 20W以上），仅标5W输入的电池充满5000mAh需3小时以上80% similarUnverified仅给手机充电不建议买60W以上大板，重量面积浪费且手机充电本身有功率上限，多余功率无法利用，20-28W带PD快充口更实用78% similarUnverified带无线充电底座的挂灯多为营销附加功能，无线充电底座会额外占据桌面面积且充电功率通常仅5-15W，若已有独立充电器则该功能溢价不值得优先考虑77% similarUnverified快充功率与设备电池非线性相关：PD 30W已能满足绝大多数手机满速快充，盲目追求65W+车充给手机充电并无提速收益，多花钱应对应有笔电/平板需求76% similar
