手機充電器大致可以分為旅行充電器、座式充電器和維(wei)護型(xing)(xing)充(chong)電器，一般用戶接觸(chu)的(de)(de)(de)主(zhu)要(yao)是(shi)前面兩種。而市場上賣得最多的(de)(de)(de)是(shi)旅行充(chong)電器，旅行充(chong)電器的(de)(de)(de)形(xing)式(shi)也(ye)有多種多樣(yang)，常(chang)見的(de)(de)(de)有價格便宜的(de)(de)(de)鴨(ya)蛋型(xing)(xing)的(de)(de)(de)微型(xing)(xing)旅充(chong)，普通臺式(shi)卡板型(xing)(xing)充(chong)電器，帶液晶顯示(shi)的(de)(de)(de)高檔臺式(shi)充(chong)電器。

所有手(shou)機充電器其實(shi)都是(shi)由一(yi)個穩定電源(yuan)（主要是(shi)穩壓電源(yuan)、提供穩定工作電壓和足(zu)夠(gou)的電流(liu)）加上必(bi)要的恒(heng)流(liu)、限(xian)壓、限(xian)時等(deng)控(kong)制電路構成。

原裝充電(dian)器(qi)（指線充）上所標注的(de)輸(shu)(shu)出(chu)(chu)參(can)(can)數：比如輸(shu)(shu)出(chu)(chu)4.4V/1A、輸(shu)(shu)出(chu)(chu)5.9V/400mA……就是(shi)指內(nei)部穩(wen)壓(ya)電(dian)源的(de)相(xiang)關參(can)(can)數。明(ming)白了這個(ge)道(dao)理，你很(hen)會知道(dao)一(yi)個(ge)（品質好的(de)）手機充電(dian)器(qi)很(hen)容易改成一(yi)個(ge)質量優良的(de)穩(wen)壓(ya)電(dian)源！ 比如輸(shu)(shu)出(chu)(chu)4.4V可以(yi)(yi)給4.5V的(de)設備用，5.9V的(de)可以(yi)(yi)給6V的(de)設備用……

　　手機常用(yong)鋰(li)離子（lion）電(dian)池的充(chong)電(dian)器采(cai)(cai)用(yong)的是恒(heng)流(liu)限壓充(chong)電(dian)制，充(chong)電(dian)電(dian)流(liu)一(yi)般(ban)采(cai)(cai)用(yong)C2左右----即(ji)采(cai)(cai)用(yong)兩(liang)小(xiao)時(shi)充(chong)電(dian)率，比如500mah電(dian)池采(cai)(cai)用(yong)250ma充(chong)電(dian)大約兩(liang)小(xiao)時(shi)達到4。2V后再恒(heng)壓充(chong)電(dian)。

　　lion電池并不適合采用NIMH電池高級快速充電器所用的-DV/DT檢測快速充電方式，因為lion電池對充電電流有嚴格的限制.鋰離子（Li+）非常活潑，大電流充電很容易產生危險。^[1]

種類

　　手(shou)機充(chong)電(dian)(dian)器大致可以分(fen)為旅行充(chong)電(dian)(dian)器、座式充(chong)電(dian)(dian)器、USB充(chong)電(dian)(dian)器和(he)維護型充(chong)電(dian)(dian)器，一般(ban)用戶接(jie)觸的

 

　　主要是前(qian)面兩種。而市(shi)場上賣得最多的(de)(de)是旅行(xing)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)，旅行(xing)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)形式(shi)也有多種多樣，常見的(de)(de)有價(jia)格便宜(yi)的(de)(de)鴨蛋型的(de)(de)微型旅充(chong)(chong)，普通臺式(shi)卡板型充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)，帶液晶顯示的(de)(de)高(gao)檔(dang)臺式(shi)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。鑒于手機用(yong)戶絕大(da)部(bu)分都(dou)是非專業用(yong)戶，所(suo)以充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)基本都(dou)具(ju)有充(chong)(chong)滿自(zi)停的(de)(de)功能，而且大(da)部(bu)分旅充(chong)(chong)都(dou)屬于快速(su)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)，充(chong)(chong)電(dian)(dian)(dian)

時間(jian)在1-3小(xiao)時左右。市場(chang)上很(hen)多充電(dian)器(qi)都標榜自己采用微(wei)電(dian)腦控制，包括(kuo)一(yi)些價格非常便宜的鴨蛋型(xing)(xing)微(wei)型(xing)(xing)旅充，其(qi)實(shi)嚴格從充電(dian)電(dian)路上分析，很(hen)小(xiao)部分充電(dian)器(qi)才(cai)能被真(zhen)正意義上被成(cheng)為(wei)微(wei)電(dian)腦控制（單片機控制）。

　　一(yi)(yi)些(xie)廠(chang)家在(zai)充(chong)(chong)電(dian)線路上使用(yong)了(le)集(ji)成(cheng)塊就(jiu)自(zi)詡(xu)為“微電(dian)腦(nao)控制”，其實很多低成(cheng)本的設計(ji)所(suo)(suo)選用(yong)的集(ji)成(cheng)塊都是廉價的運放集(ji)成(cheng)塊，而一(yi)(yi)些(xie)專用(yong)的充(chong)(chong)電(dian)控制集(ji)成(cheng)塊單價較高，一(yi)(yi)般(ban)用(yong)于比較高檔或名(ming)牌(pai)的充(chong)(chong)電(dian)器中。所(suo)(suo)以我們不能(neng)輕信所(suo)(suo)謂(wei)微電(dian)腦(nao)控制，尤其是廉價型產品。很多產品外觀類似(si)但(dan)內(nei)部線路卻(que)大不一(yi)(yi)樣，其性能(neng)也大不同。

功能

　　1、質量(liang)好的(de)(de)座(zuo)充能(neng)夠識(shi)別(bie)鋰電(dian)(dian)池(chi)與鎳氫電(dian)(dian)池(chi)，進而決(jue)(jue)定(ding)(ding)充電(dian)(dian)模式。鋰電(dian)(dian)池(chi)的(de)(de)保護電(dian)(dian)路板上有一塊集成電(dian)(dian)路儲存著鋰電(dian)(dian)池(chi)的(de)(de)特性(xing)資料，它一方(fang)面讓座(zuo)充能(neng)夠識(shi)別(bie)鋰電(dian)(dian)池(chi)，以決(jue)(jue)定(ding)(ding)“定(ding)(ding)電(dian)(dian)流”及“定(ding)(ding)電(dian)(dian)壓”充電(dian)(dian)模式；另一方(fang)面也讓手(shou)機(ji)能(neng)識(shi)別(bie)鋰電(dian)(dian)池(chi)，以決(jue)(jue)定(ding)(ding)放電(dian)(dian)方(fang)式。

　　2、鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)的充電(dian)方式采用(yong)“定電(dian)流”。鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)本身不怕過(guo)充電(dian)，當鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)過(guo)充時會(hui)有(you)(you)反向反應，以(yi)防(fang)止電(dian)壓(ya)過(guo)度上(shang)升，此反應會(hui)使電(dian)池(chi)微(wei)微(wei)發(fa)熱(re)。此外，鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)通常都加有(you)(you)一個熱(re)敏電(dian)阻，以(yi)防(fang)止電(dian)池(chi)過(guo)度充電(dian)。目前(qian)，大(da)部分手(shou)機(ji)的工作電(dian)壓(ya)是3.6V左右，故(gu)需三節鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)芯(xin)。而一般鎳(nie)氫(qing)(qing)(qing)電(dian)池(chi)芯(xin)過(guo)充至約1.4～1.5V左右即停止，三節電(dian)池(chi)最高電(dian)壓(ya)為4.4V左右。

　　3、由于鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過充(chong)(chong)(chong)(chong)會發生危險(xian)，故對充(chong)(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)的(de)設(she)定條(tiao)件比鎳(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和(he)鎳(nie)(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)都要苛刻。鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內部通常附(fu)加一(yi)塊控制電(dian)(dian)(dian)(dian)(dian)(dian)路板以防(fang)止過充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。根據鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)特性(xing)設(she)計，第一(yi)段充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是以“定電(dian)(dian)(dian)(dian)(dian)(dian)流”方(fang)式(shi)(shi)(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，等(deng)(deng)到(dao)快(kuai)充(chong)(chong)(chong)(chong)飽時(shi)再以“定電(dian)(dian)(dian)(dian)(dian)(dian)壓”(約4.1～4.2V之間)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)方(fang)式(shi)(shi)(shi)使電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)達到(dao)最佳(jia)狀態。市面上有些座充(chong)(chong)(chong)(chong)偷工減料，把手機電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)一(yi)律(lv)識別(bie)成鎳(nie)(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，而以“定電(dian)(dian)(dian)(dian)(dian)(dian)流”方(fang)式(shi)(shi)(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，往(wang)往(wang)容易導致鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。品質佳(jia)的(de)保護電(dian)(dian)(dian)(dian)(dian)(dian)路板此時(shi)會將鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)保護，以防(fang)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)繼續充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。若遇到(dao)設(she)計不良的(de)電(dian)(dian)(dian)(dian)(dian)(dian)路板，不僅無法保護電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，造成電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)可能(neng)因過度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)導致電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)芯變形、漏液、暴****炸等(deng)(deng)等(deng)(deng)。

　　4、座(zuo)充(chong)(chong)大多采用快速充(chong)(chong)電(dian)(dian)，一般在3～4個小時(shi)即(ji)已充(chong)(chong)滿。當(dang)座(zuo)充(chong)(chong)顯示(shi)充(chong)(chong)電(dian)(dian)完畢時(shi)，即(ji)使(shi)不將(jiang)電(dian)(dian)池(chi)從座(zuo)充(chong)(chong)取下，也只剩下極(ji)微弱的電(dian)(dian)量進入電(dian)(dian)池(chi)。

　　5、鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)記憶(yi)效應(ying)并不大，不需常(chang)常(chang)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)則基本不需放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。市面上銷售的(de)(de)充電(dian)(dian)(dian)(dian)(dian)器，其所附的(de)(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)裝置質量(liang)不一(yi)。質量(liang)差的(de)(de)會有過放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)的(de)(de)現象，易造成電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內(nei)部負極板的(de)(de)腐(fu)蝕(shi)(鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內(nei)部的(de)(de)電(dian)(dian)(dian)(dian)(dian)解(jie)質是氫(qing)氧化鉀堿性溶(rong)液(ye))，進而減(jian)少電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)壽命及平時可使用的(de)(de)容量(liang)。在這種情況下，每次都先放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)再充電(dian)(dian)(dian)(dian)(dian)的(de)(de)話，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)會壞得(de)更(geng)快(kuai)。正常(chang)情況下，只要把一(yi)節電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)用到自動關機后再去充電(dian)(dian)(dian)(dian)(dian)，就是對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)最好的(de)(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)處理方法。

性能(neng)特點

　　在(zai)使用過(guo)程中我(wo)們也(ye)可以檢驗充電器的(de)性能。在(zai)充電的(de)后期電池有(you)略微的(de)溫升

是正常現象，但(dan)如果電池明顯發燙，則(ze)說明充(chong)(chong)電器未能(neng)及時檢(jian)測到(dao)電池充(chong)(chong)電已飽和，造成過充(chong)(chong)，這對電池的壽命不利。

　　很多充電(dian)(dian)器(qi)(qi)雖然沒(mei)有(you)過充現(xian)(xian)象，但(dan)存在充電(dian)(dian)不(bu)足的(de)問題，直接表(biao)現(xian)(xian)為電(dian)(dian)池放電(dian)(dian)時間短(duan)，即手(shou)機(ji)待機(ji)通(tong)話時間短(duan)。在使(shi)用原裝隨機(ji)新(xin)電(dian)(dian)池的(de)用戶，可(ke)以比較說明書上提供的(de)大致(zhi)參照時間，加以對比，如果參考數(shu)值與實際使(shi)用明顯存在差(cha)距，則有(you)理由懷(huai)疑充電(dian)(dian)器(qi)(qi)的(de)問題，當然也(ye)不(bu)排(pai)除電(dian)(dian)池質(zhi)量、手(shou)機(ji)使(shi)用環境等其(qi)他因素。

充(chong)電方式

　　充(chong)電(dian)(dian)的方(fang)式(shi)最為(wei)關(guan)鍵，對鋰電(dian)(dian)池(chi)充(chong)電(dian)(dian)需要專門支持鋰電(dian)(dian)池(chi)充(chong)電(dian)(dian)模式(shi)的充(chong)電(dian)(dian)器，

一般在充(chong)(chong)電(dian)(dian)器(qi)的包(bao)裝上有(you)標注。很多充(chong)(chong)電(dian)(dian)器(qi)兼容兩種充(chong)(chong)電(dian)(dian)模式，選(xuan)購時要(yao)注意是自動識別還是手(shou)動靠(kao)(kao)開(kai)關設定，如果是人工設定，則必須根(gen)據所充(chong)(chong)電(dian)(dian)池的類型正(zheng)確(que)設定。對于鎳鎘/鎳氫電(dian)(dian)池，優秀(xiu)的充(chong)(chong)電(dian)(dian)器(qi)采用(yong)帶下(xia)拉(la)負脈充(chong)(chong)的充(chong)(chong)電(dian)(dian)方式，可以在充(chong)(chong)電(dian)(dian)過程中減小極(ji)化效(xiao)應。而(er)普通(tong)廉價充(chong)(chong)電(dian)(dian)器(qi)則使用(yong)恒(heng)流充(chong)(chong)電(dian)(dian)。電(dian)(dian)池充(chong)(chong)電(dian)(dian)波(bo)形要(yao)靠(kao)(kao)示波(bo)器(qi)才能準確(que)觀(guan)察。

選購方法(fa)

　　選購兼(jian)容(rong)手機充(chong)電器(qi)也要講究品牌，應該是正規廠家(jia)生產(chan)的商品。因為上面(mian)雖(sui)

然介紹(shao)一些充(chong)(chong)(chong)電器(qi)的(de)原(yuan)理(li)，但(dan)實(shi)際識別(bie)卻非常(chang)困難(nan)(nan)。即便是專業(ye)人士，在不打開充(chong)(chong)(chong)電器(qi)、不使(shi)用測試儀器(qi)的(de)情況(kuang)下，也很難(nan)(nan)從(cong)充(chong)(chong)(chong)電器(qi)外表準確判斷充(chong)(chong)(chong)電器(qi)的(de)性(xing)能(neng)與質量。一些著(zhu)名(ming)品牌的(de)產品雖然價(jia)格會略高一些，但(dan)從(cong)線(xian)路設計到(dao)元件選用都比(bi)較正規科(ke)學，所以充(chong)(chong)(chong)電效果也比(bi)較理(li)想對(dui)于(yu)非原(yuan)裝的(de)座充(chong)(chong)(chong)還要看(kan)模具的(de)精(jing)細程(cheng)度，手機插拔能(neng)否一次到(dao)位，而(er)且阻力均勻、松緊(jin)適度。對(dui)于(yu)部(bu)分直接對(dui)電池充(chong)(chong)(chong)電的(de)座充(chong)(chong)(chong)，同(tong)前面提到(dao)的(de)旅充(chong)(chong)(chong)一樣，看(kan)它線(xian)路設計合理(li)程(cheng)度。

統(tong)一接(jie)口標準

　　2009年2月18日 GSM協(xie)會聯合17家移動(dong)運營商和(he)制造商宣布，將在全(quan)球建立統一的手機(ji)

充電器(qi)連接(jie)標(biao)準(zhun)，計劃自2012年1月1日(ri)起(qi)，所有上市(shi)的(de)手機(ji)產品中(zhong)絕大部(bu)分都將支持統一連接(jie)標(biao)準(zhun)的(de)手機(ji)充電器(qi)。

　　手機端接口也實現統一

　　上述標準計劃采用Micro-USB為通用充電接口，并節約50%充電時的能耗。與中國已經實施的統一接口標準不同的是，該標準將手機連接充電器的接口也實現統一。而中國目前正在的實施的標準實質是“在變壓器加裝了USB接口”，手機充電器改為由(you)一(yi)根USB數據線(xian)和一(yi)個帶有(you)USB接口的充(chong)電器座，手機(ji)一(yi)端的接口并沒(mei)有(you)要求統(tong)一(yi)。這意味著GSM協會(hui)公布的統(tong)一(yi)充(chong)電器接口標準的變革更加(jia)徹底。

　　這(zhe)次諾基亞、三星、摩托(tuo)羅拉(la)、索尼愛立信及LG均(jun)表現出了積(ji)極的態度。他(ta)們與和黃3Group、美國(guo)電(dian)(dian)報電(dian)(dian)話公司、韓國(guo)電(dian)(dian)信、法國(guo)電(dian)(dian)信、高(gao)通、意大(da)利電(dian)(dian)信、西班牙電(dian)(dian)信、澳大(da)利亞電(dian)(dian)信、德(de)國(guo)電(dian)(dian)信和沃達豐等電(dian)(dian)信巨頭 一起參(can)與了此計劃。

 

　　建(jian)立(li)統一標準(zhun)有(you)可(ke)(ke)(ke)(ke)能(neng)消(xiao)除高達(da)5.1萬(wan)噸的(de)充電器(qi)復制(zhi)品(pin)，消(xiao)費(fei)者可(ke)(ke)(ke)(ke)用(yong)同一個充電器(qi)為不同品(pin)牌(pai)的(de)手機充電，可(ke)(ke)(ke)(ke)減(jian)輕消(xiao)費(fei)者負擔。與此同時，由于(yu)每年制(zhi)造出的(de)充電器(qi)有(you)可(ke)(ke)(ke)(ke)能(neng)減(jian)少50%能(neng)耗，預計每年在(zai)制(zhi)造和運輸(shu)充電器(qi)替代品(pin)的(de)過程中將能(neng)減(jian)少1360萬(wan)到(dao)2180萬(wan)噸的(de)溫(wen)室(shi)氣體。

　　現(xian)階段只有蘋果公(gong)司要(yao)求(qiu)充(chong)電(dian)器輸出電(dian)流達到1000mA，剩下廠家都(dou)僅僅適應(ying)了USB供電(dian)能力（約500mA）。因為500mA的電(dian)流達不(bu)到玩手(shou)(shou)機(ji)(ji)時(shi)手(shou)(shou)機(ji)(ji)消(xiao)耗功率，所以使(shi)用蘋果手(shou)(shou)機(ji)(ji)不(bu)需要(yao)擔心(xin)一邊充(chong)電(dian)一邊玩游(you)戲時(shi)會對(dui)電(dian)池的損壞。

保養

　　1、清(qing)洗時(shi)放靜電。定期(qi)清(qing)潔(jie)充(chong)電器和充(chong)電接口。清(qing)理(li)時(shi)，要(yao)用一塊濕布(bu)，或者(zhe)一件抗靜電布(bu)。切勿(wu)使用干燥布(bu)（靜電電荷）！

　　2、防(fang)水防(fang)潮。作為(wei)電子產品，不(bu)(bu)小心進水或者(zhe)長時(shi)間不(bu)(bu)用時(shi)暴露在潮濕的空(kong)氣中，都會對其內部的電子元件造成(cheng)不(bu)(bu)同程度的腐蝕或氧化。

　　3、防(fang)摔防(fang)震。手(shou)機充電(dian)器(qi)(qi)其(qi)實(shi)是一個(ge)脆弱的部(bu)件(jian)，內(nei)部(bu)元器(qi)(qi)件(jian)經不起摔打。尤其(qi)要(yao)防(fang)止在(zai)使用過程中不小心落地。不要(yao)扔放、敲打或震動(dong)充電(dian)器(qi)(qi)。粗暴(bao)地對待充電(dian)器(qi)(qi)會毀壞內(nei)部(bu)電(dian)路板

　　4、防冷防熱。不要將充電器(qi)(qi)放在(zai)溫(wen)(wen)度(du)過高的(de)地(di)方。高溫(wen)(wen)會縮(suo)短電子器(qi)(qi)件(jian)的(de)壽命，毀壞充電器(qi)(qi)，使有些塑料部件(jian)變形或熔(rong)化。也不要將充電器(qi)(qi)存放在(zai)過冷的(de)地(di)方。當充電器(qi)(qi)在(zai)過冷的(de)環境(jing)工(gong)作時(shi)，內部溫(wen)(wen)度(du)升高時(shi)，充電器(qi)(qi)內會形成潮氣(qi)，毀壞電路板。

　　5 、防烈性(xing)化學制品。不(bu)要(yao)用(yong)烈性(xing)化學制品、清洗(xi)劑(ji)或強洗(xi)滌劑(ji)清洗(xi)充電(dian)器。清除充電(dian)器外觀(guan)污漬(zi)可(ke)用(yong)棉花沾少量無水酒(jiu)精(jing)擦洗(xi)。
