在購買快充電源適配(pei)器時(shi)，應首先考慮充(chong)(chong)電(dian)器的(de)種類、設備數量、充(chong)(chong)電(dian)速(su)(su)度等(deng)綜合因(yin)素。如需(xu)要(yao)為多臺設備充(chong)(chong)電(dian)，并且對(dui)充(chong)(chong)電(dian)速(su)(su)度也沒有什(shen)么要(yao)求(qiu)的(de)話，則選擇(ze)多口座充(chong)(chong)式充(chong)(chong)電(dian)器。

電(dian)(dian)(dian)(dian)源適配器一(yi)般有兩種(zhong)充(chong)電(dian)(dian)(dian)(dian)功能：一(yi)種(zhong)是帶機充(chong)電(dian)(dian)(dian)(dian)(充(chong)電(dian)(dian)(dian)(dian)器通(tong)過電(dian)(dian)(dian)(dian)連接器與手機配合給電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian))，另一(yi)種(zhong)是通(tong)過充(chong)電(dian)(dian)(dian)(dian)座給電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)。選購前應(ying)清楚自己所用(yong)電(dian)(dian)(dian)(dian)池的類型、容量、標(biao)稱電(dian)(dian)(dian)(dian)壓(ya)，以便選購與之適配的充(chong)電(dian)(dian)(dian)(dian)器。

貼有(you)“CCC”認(ren)證(zheng)標志(zhi)的電源適(shi)(shi)配器(qi)才有(you)安全保證(zheng)。因此，應盡量選購有(you)“CCC”或其他認(ren)證(zheng)標志(zhi)的產(chan)品。其次選購與自己手機適(shi)(shi)配的電源適(shi)(shi)配器(qi)

選購快充類(lei)電(dian)(dian)(dian)源適(shi)配器(qi)時(shi)，應查看(kan)自己的手(shou)(shou)(shou)機(ji)型號是否支持該類(lei)型快充協(xie)議。要知道，快充技術并不(bu)是相互兼容的。在(zai)選購旅行(xing)充電(dian)(dian)(dian)器(qi)時(shi)，首先注意其接口應能與手(shou)(shou)(shou)機(ji)的充電(dian)(dian)(dian)接口完(wan)全(quan)吻合。切忌選擇接口松動(dong)或者接口過(guo)緊的旅行(xing)充電(dian)(dian)(dian)器(qi)。接口松動(dong)會讓手(shou)(shou)(shou)機(ji)接收到的電(dian)(dian)(dian)流(liu)不(bu)穩(wen)定，還有可能形成(cheng)較大的瞬間電(dian)(dian)(dian)流(liu)，對手(shou)(shou)(shou)機(ji)主板造成(cheng)損傷(shang)。

選擇(ze)寬頻(pin)輸入電(dian)壓，即100~220v/50~60Hz，有(you)些國外的(de)充電(dian)頭只有(you)110v輸入電(dian)壓，拿回國內如果直接使(shi)用，輕則(ze)燒壞電(dian)源適配器，重則(ze)燒壞手機。
