USB Power Delivery ，簡稱USB PD，是由USB-IF組織製定的(de)(de)(de)一(yi)種(zhong)快速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)規範，目前主(zhu)流(liu)(liu)的(de)(de)(de)快充(chong)協議之一(yi)。該規範可(ke)實現更高(gao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，輸送的(de)(de)(de)功(gong)率最高(gao)可(ke)達(da)100瓦(wa)，並可(ke)以(yi)自由的(de)(de)(de)改(gai)變電(dian)(dian)(dian)(dian)(dian)(dian)力的(de)(de)(de)輸送方(fang)向。在(zai)日常(chang)使(shi)用USB PD快充(chong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器時，需要頻繁地(di)熱(re)插(cha)拔。如(ru)果其(qi)內部防護(hu)措施不到位的(de)(de)(de)話，不僅會導致浪湧(yong)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)通過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)源線進入(ru)內部電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)損壞(huai)主(zhu)控(kong)芯片，而且還容易(yi)(yi)引發(fa)輸出瞬間大電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，影(ying)響充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)穩定和(he)(he)安全，甚(shen)至導致受充(chong)設備損壞(huai)。不僅如(ru)此(ci)，USB PD快充(chong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器和(he)(he)快充(chong)移(yi)動電(dian)(dian)(dian)(dian)(dian)(dian)源產(chan)(chan)品(pin)在(zai)使(shi)用中(zhong)，很容易(yi)(yi)與人(ren)體(ti)或其(qi)他帶靜電(dian)(dian)(dian)(dian)(dian)(dian)物體(ti)產(chan)(chan)生接(jie)(jie)觸，而多(duo)數產(chan)(chan)品(pin)外殼(ke)的(de)(de)(de)殼(ke)料與USB端口、呼吸燈、按鍵的(de)(de)(de)連接(jie)(jie)處並不是無(wu)縫設計，外部靜電(dian)(dian)(dian)(dian)(dian)(dian)很容易(yi)(yi)通過(guo)接(jie)(jie)縫進入(ru)主(zhu)板中(zhong)，導致產(chan)(chan)品(pin)損壞(huai)。
