手機充電器(qi)，又(you)名移(yi)動電(dian)(dian)源(yuan)(yuan)、充(chong)電(dian)(dian)寶，其實都是由(you)一個(ge)(ge)穩定(ding)電(dian)(dian)源(yuan)(yuan)（主要(yao)是穩壓(ya)(ya)電(dian)(dian)源(yuan)(yuan)、提供穩定(ding)工作電(dian)(dian)壓(ya)(ya)和足夠(gou)的(de)電(dian)(dian)流(liu)）加上必要(yao)的(de)恒流(liu)、限(xian)壓(ya)(ya)、限(xian)時等控制電(dian)(dian)路構成。原裝充(chong)電(dian)(dian)器(qi)（指線充(chong)）上所標注的(de)輸(shu)出(chu)參(can)數(shu)：比(bi)如(ru)輸(shu)出(chu)5.0V/1A、輸(shu)出(chu)5.0V/1500mA-11200……就(jiu)是指內(nei)部穩壓(ya)(ya)電(dian)(dian)源(yuan)(yuan)的(de)相關參(can)數(shu)。明白了這個(ge)(ge)道理，你很會知道一個(ge)(ge)（品(pin)質(zhi)好的(de)）手機充(chong)電(dian)(dian)器(qi)很容易改成一個(ge)(ge)質(zhi)量優良的(de)穩壓(ya)(ya)電(dian)(dian)源(yuan)(yuan)！

手機常用(yong)鋰離子（li-ion）電(dian)(dian)池的充電(dian)(dian)器采用(yong)的是恒流限壓(ya)(ya)充電(dian)(dian)制，充電(dian)(dian)電(dian)(dian)流一(yi)般采用(yong)C2左(zuo)右----即采用(yong)兩(liang)小時充電(dian)(dian)率(lv)，比如500mAh電(dian)(dian)池采用(yong)250mA充電(dian)(dian)大約兩(liang)小時達到4。2V后再恒壓(ya)(ya)充電(dian)(dian)。

按使用方式分

1、旅行式充電器：該類(lei)型充(chong)電器體(ti)積小(xiao)巧，易(yi)于攜帶(dai)，可(ke)(ke)為可(ke)(ke)拆卸電池(chi)充(chong)電。但隨著不可(ke)(ke)拆卸式電池(chi)的(de)普及(ji)，此類(lei)充(chong)電器逐漸(jian)減少。

2、座式充電器：外型獨特(te)、新穎美觀、攜帶方(fang)便(bian)，并內置智能(neng)識(shi)別電路，能(neng)自動(dong)轉換充(chong)電器(qi)輸出極性以適用(yong)電池(chi)正負(fu)極，充(chong)電效果最佳(jia)。

3、多口座充式充電器：該類型充(chong)電(dian)器(qi)具備多(duo)個USB充(chong)電(dian)口，可為手機、平板(ban)電(dian)腦等多(duo)種數(shu)碼產品充(chong)電(dian)，非常適合家用(yong)。但此類充(chong)電(dian)器(qi)往(wang)往(wang)體積較(jiao)大，充(chong)電(dian)速(su)度(du)也較(jiao)慢。

4、車載充電器：以車上通用(yong)電源為供電裝置的(de)充電器(qi)。

按快充技術分(fen)

目(mu)前來(lai)說，快(kuai)充(chong)技術主要分為(wei)三(san)種(zhong)：Quick Charge快(kuai)充(chong)技術、Pump Express快(kuai)充(chong)技術和USB PD快(kuai)充(chong)技術。其余快(kuai)充(chong)協議也大都為(wei)以上(shang)三(san)種(zhong)快(kuai)充(chong)技術的衍(yan)生。

1、Quick Charge快充技術：該(gai)快充(chong)技(ji)術(shu)由美國(guo)高通公(gong)司研發，第(di)三代的QC 3.0也已經正式商用(yong)。該(gai)快充(chong)技(ji)術(shu)主要通過提升電壓來(lai)提高充(chong)電效(xiao)率，技(ji)術(shu)較為成(cheng)熟。

2、Pump Express快充技術：該快(kuai)(kuai)充(chong)技術(shu)由聯發科(ke)主導，通過智能分析電(dian)(dian)流決定(ding)充(chong)電(dian)(dian)所需的初始電(dian)(dian)壓(ya)，充(chong)電(dian)(dian)器依照(zhao)此指令(ling)調節輸出電(dian)(dian)壓(ya)，從而達(da)到為手機快(kuai)(kuai)速充(chong)電(dian)(dian)的目的。

3、USB PD快充技術：該快充標準分10W、18W、36W、60W、100W五種規格，電壓為5V、12V和20V，電流則為1.5A、2A、3A和5A。詳細>>

1、購(gou)買手(shou)機充(chong)(chong)電(dian)器(qi)時，應首先考慮(lv)充(chong)(chong)電(dian)器(qi)的(de)種類(lei)、設備數量、充(chong)(chong)電(dian)速度等(deng)綜合因素。如需要(yao)為多臺設備充(chong)(chong)電(dian)，并且對充(chong)(chong)電(dian)速度也沒有什么要(yao)求的(de)話，則選(xuan)擇多口(kou)座充(chong)(chong)式(shi)充(chong)(chong)電(dian)器(qi)。

2、手(shou)機充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)一(yi)般有兩種充(chong)(chong)電(dian)(dian)(dian)(dian)功能：一(yi)種是帶機充(chong)(chong)電(dian)(dian)(dian)(dian)（充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)通過(guo)電(dian)(dian)(dian)(dian)連接器(qi)與手(shou)機配合給電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)），另一(yi)種是通過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)座(zuo)給電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)。選(xuan)購(gou)前應清(qing)楚自己所用電(dian)(dian)(dian)(dian)池(chi)的類型、容量、標(biao)稱(cheng)電(dian)(dian)(dian)(dian)壓，以便選(xuan)購(gou)與之適配的充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)。

3、貼有(you)“CCC”認證(zheng)(zheng)標(biao)志(zhi)的充電器(qi)(qi)才(cai)有(you)安全保證(zheng)(zheng)。因此，應(ying)盡量(liang)選購有(you)“CCC”或其他認證(zheng)(zheng)標(biao)志(zhi)的產(chan)品。其次選購與(yu)自(zi)己手機適配的充電器(qi)(qi)。

4、選(xuan)購快(kuai)充(chong)(chong)類手(shou)機(ji)充(chong)(chong)電器時，應查看自己的(de)手(shou)機(ji)型(xing)號是否(fou)支持該(gai)類型(xing)快(kuai)充(chong)(chong)協(xie)議。要知道，快(kuai)充(chong)(chong)技(ji)術并不是相互兼容的(de)。

5、在選購旅(lv)行充(chong)電(dian)器時，首先注意其(qi)接(jie)(jie)(jie)口應能(neng)與手機的充(chong)電(dian)接(jie)(jie)(jie)口完全吻合。切忌選擇(ze)接(jie)(jie)(jie)口松(song)動或者接(jie)(jie)(jie)口過緊的旅(lv)行充(chong)電(dian)器。接(jie)(jie)(jie)口松(song)動會讓(rang)手機接(jie)(jie)(jie)收到的電(dian)流(liu)不穩定，還有可能(neng)形成(cheng)(cheng)較(jiao)大的瞬間(jian)電(dian)流(liu)，對手機主板造(zao)成(cheng)(cheng)損傷。

6、選擇(ze)寬頻輸入(ru)電壓，即(ji)100~220v/50~60Hz，有(you)些(xie)國外的充電頭只(zhi)有(you)110v輸入(ru)電壓，拿回國內如果(guo)直接使用，輕則燒壞(huai)充電器，重(zhong)則燒壞(huai)手機。

7、手機充電器國家標準GB/T 21544-2008 移動通信手持機用鋰離子電源充電器。充電器表面應有中文標示，包括制造廠商，產品型號，產品名稱，輸入電壓及電流輸入頻率，輸出電壓及電流，正負極，警示說明等。詳細>>

1、清洗時放靜(jing)電定期清(qing)潔(jie)充電(dian)(dian)器(qi)和充電(dian)(dian)接口。清(qing)理時，要用一塊濕布(bu)，或(huo)者一件抗靜電(dian)(dian)布(bu)。切勿使用干(gan)燥布(bu)(會有(you)靜電(dian)(dian)電(dian)(dian)荷(he))！

2、防水(shui)防潮作(zuo)為(wei)電子(zi)產品(pin)，不小(xiao)心(xin)進(jin)水或(huo)者長(chang)時間(jian)不用時暴露在(zai)潮濕(shi)的空氣(qi)中，都(dou)會對(dui)其內部的電子(zi)元件(jian)造(zao)成不同程(cheng)度的腐蝕或(huo)氧化(hua)。

3、防(fang)摔防(fang)震手機充電(dian)(dian)器(qi)其(qi)實是一個(ge)脆弱的部(bu)件(jian)，內部(bu)元(yuan)器(qi)件(jian)經(jing)不(bu)起摔打(da)。尤其(qi)要防止在使用過程中不(bu)小心落地(di)(di)。不(bu)要扔(reng)放、敲打(da)或(huo)震動充電(dian)(dian)器(qi)。粗暴(bao)地(di)(di)對待充電(dian)(dian)器(qi)會(hui)毀壞內部(bu)電(dian)(dian)路板。

4、防冷(leng)防熱不要將(jiang)充(chong)(chong)(chong)電器(qi)(qi)(qi)放在(zai)溫(wen)度過高的(de)地方(fang)。高溫(wen)會縮短(duan)電子器(qi)(qi)(qi)件的(de)壽(shou)命(ming)，毀壞充(chong)(chong)(chong)電器(qi)(qi)(qi)，使(shi)有些(xie)塑料部(bu)(bu)件變形或熔化。也不要將(jiang)充(chong)(chong)(chong)電器(qi)(qi)(qi)存放在(zai)過冷(leng)的(de)地方(fang)。當充(chong)(chong)(chong)電器(qi)(qi)(qi)在(zai)過冷(leng)的(de)環境(jing)工作時，內(nei)部(bu)(bu)溫(wen)度升高時，充(chong)(chong)(chong)電器(qi)(qi)(qi)內(nei)會形成潮氣，毀壞電路板。

5、防烈性化學制品不要用烈性化學制品、清洗劑或強洗滌劑清洗充電器。清除充電器外觀污漬可用棉花沾少量無水酒精擦洗。詳細>>
