很(hen)多消費者都認(ren)為電源適配器都是(shi)一樣，所以(yi)往往會(hui)選擇外表一樣，但是(shi)價格便宜的，但是(shi)這類(lei)帶電(dian)源適配器很有(you)可能是(shi)商家用一些三無產品替換(huan)的，沒有(you)質量保證，容易發生(sheng)危險。因此建議消費者通過正規(gui)渠道進行(xing)購買。

購買時也不(bu)一(yi)定(ding)是充(chong)電(dian)(dian)(dian)(dian)(dian)速(su)(su)度(du)越(yue)(yue)快(kuai)的(de)越(yue)(yue)好，充(chong)電(dian)(dian)(dian)(dian)(dian)速(su)(su)度(du)主要(yao)和(he)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器提供的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)有關。充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)越(yue)(yue)大，充(chong)電(dian)(dian)(dian)(dian)(dian)速(su)(su)度(du)越(yue)(yue)快(kuai)。需要(yao)注(zhu)意(yi)的(de)是，充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)越(yue)(yue)大，對(dui)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器和(he)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)內(nei)部體系(xi)設計(ji)品質要(yao)求越(yue)(yue)高。充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)越(yue)(yue)大，充(chong)電(dian)(dian)(dian)(dian)(dian)過程中可(ke)能(neng)導致的(de)發(fa)熱越(yue)(yue)多(duo)，電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)性能(neng)可(ke)能(neng)受到(dao)的(de)損害越(yue)(yue)大。

另外(wai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器要選擇寬頻輸入電(dian)(dian)(dian)(dian)壓(ya)，即100~220v/50~60Hz，有(you)些(xie)國外(wai)的充電(dian)(dian)(dian)(dian)頭只(zhi)有(you)110v輸入電(dian)(dian)(dian)(dian)壓(ya)，拿回國內如果(guo)直接使(shi)用(yong)，輕則燒(shao)壞充電(dian)(dian)(dian)(dian)器，重(zhong)則燒(shao)壞手(shou)(shou)機。手(shou)(shou)機充電(dian)(dian)(dian)(dian)器國家標準(zhun)GB/T 21544-2008 移(yi)動通信手(shou)(shou)持機用(yong)鋰離(li)子電(dian)(dian)(dian)(dian)源(yuan)(yuan)充電(dian)(dian)(dian)(dian)器。電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器表面(mian)應有(you)中(zhong)文(wen)標示，包(bao)括制造廠商，產品型(xing)號(hao)，產品名稱，輸入電(dian)(dian)(dian)(dian)壓(ya)及電(dian)(dian)(dian)(dian)流(liu)輸入頻率，輸出電(dian)(dian)(dian)(dian)壓(ya)及電(dian)(dian)(dian)(dian)流(liu)，正負極，警示說明等。

以上這些就是我們在購買電(dian)源適(shi)配器(qi)時(shi)需要(yao)注(zhu)意的(de)(de)問題，以及需要(yao)避免的(de)(de)坑，希望大家都能正(zheng)確(que)使用電(dian)源適(shi)配器(qi)，安(an)全(quan)充電(dian)。
