隨著全球濟濟的(de)(de)快速發(fa)展，外出(chu)旅游的(de)(de)人越來越多，隨身攜帶式的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子產品也(ye)越來越多，如手(shou)機(ji)、數碼相機(ji)、mp4、GPS等，都是(shi)(shi)要(yao)(yao)用(yong)(yong)(yong)到電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，但這些設(she)(she)備(bei)(bei)的(de)(de)隨機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)都會因為電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量低(di)而顯(xian)得不能滿足設(she)(she)備(bei)(bei)的(de)(de)正常使用(yong)(yong)(yong)時間，但旅行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)出(chu)現(xian)卻(que)很好的(de)(de)解(jie)決了這個(ge)問題(ti)。旅行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，英文名(ming)稱Charger,通(tong)常指的(de)(de)是(shi)(shi)專為蓄電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)置提供能量的(de)(de)設(she)(she)備(bei)(bei)。充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)主要(yao)(yao)是(shi)(shi)采用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)子半導體器(qi)(qi)件，將電(dian)(dian)(dian)(dian)(dian)(dian)壓和頻(pin)率(lv)固(gu)定不變的(de)(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)變換為直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)一(yi)種靜止變流(liu)裝(zhuang)置。在以蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)為工作電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)或備(bei)(bei)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)場合，現(xian)在充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)具有廣泛(fan)的(de)(de)應(ying)用(yong)(yong)(yong)前景。

    充電器有很多，如蓄電池充電器、車充和外置電池充電器等,也(ye)叫“外掛電(dian)(dian)(dian)(dian)池”，移(yi)動(dong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)充(chong)電(dian)(dian)(dian)(dian)器是(shi)隨(sui)著(zhu)目前數碼產(chan)品(pin)的(de)普及(ji)和(he)快速增長而(er)發展起來(lai)的(de)，其定(ding)義就是(shi)方便易(yi)攜(xie)帶(dai)的(de)大容量隨(sui)身電(dian)(dian)(dian)(dian)源(yuan)(yuan)。擁有該充(chong)電(dian)(dian)(dian)(dian)器，就可以在移(yi)動(dong)狀態中(zhong)隨(sui)時隨(sui)地為多(duo)種數碼產(chan)品(pin)提(ti)供電(dian)(dian)(dian)(dian)能(供電(dian)(dian)(dian)(dian)或充(chong)電(dian)(dian)(dian)(dian))。

　　蓄電池等電池充電器主要(yao)是靠貯存化學能量，于必要(yao)時放(fang)出電(dian)能的一種電(dian)氣(qi)化學設備。該電(dian)池主要(yao)是通過鉛蓄電(dian)池內(nei)的陽極(PbO2)及陰極(Pb)浸到電(dian)解

液(稀硫(liu)酸)中，兩極間產生2V的電(dian)力(li)來實(shi)現充(chong)放電(dian)等功能，形狀大小上不同(tong)，而且(qie)有些不能直接的使(shi)用第二次。

　　車(che)(che)充(chong)，又稱為(wei)車(che)(che)載(zai)充(chong)電器是為(wei)了方便車(che)(che)主旅游時用車(che)(che)載(zai)電源隨時隨地為(wei)數碼(ma)產(chan)品充(chong)電的配件(jian)。目前部(bu)分高端車(che)(che)載(zai)充(chong)電器一般包括(kuo)2個USB接口，可同時為(wei)

  

 

兩臺(tai)數(shu)碼產品充電(dian)。這類產品一般具有過載保(bao)護(hu)(hu)，短路保(bao)護(hu)(hu)，高(gao)壓輸(shu)入保(bao)護(hu)(hu)，高(gao)溫保(bao)護(hu)(hu)，四重安(an)全保(bao)護(hu)(hu)功(gong)(gong)能(neng)，確保(bao)能(neng)安(an)全使用(yong)。車載充電(dian)器在車用(yong)的(de)同時(shi)，也(ye)能(neng)家用(yong)，實現車充、直充、USB充三合一多功(gong)(gong)能(neng)用(yong)途(tu)

旅行充(chong)電(dian)器注意事項

　　1）、旅行充電(dian)器在(zai)給手機電(dian)池的充電(dian)過(guo)程中要注意電(dian)源的輸(shu)出電(dian)壓(ya)必(bi)須要在(zai)規定能(neng)夠的范圍內(nei)，否則實(shi)現不(bu)了充電(dian)功能(neng)。

　　2）、要保持充電器干燥，因(yin)為雨水、濕氣和各種(zhong)液體或水分都(dou)有可能含有礦物(wu)質，會腐蝕電子元件和線路。

　　3）、不要放在高(gao)(gao)溫處。高(gao)(gao)溫將縮短(duan)電(dian)子裝置的壽(shou)命(ming)、損(sun)壞電(dian)池(chi)并使某(mou)些塑料老化。

　　4）、在購(gou)買旅行(xing)充(chong)電器(qi)時(shi)最好到(dao)廠家授(shou)權的(de)專營(ying)店(柜)購(gou)買，這樣可保證買到(dao)品質(zhi)正(zheng)宗的(de)原(yuan)裝配件。因隨便的(de)選用(yong)，可能會(hui)使被充(chong)的(de)電器(qi)達不到(dao)最佳使用(yong)狀(zhuang)態，嚴重者甚至影響(xiang)其正(zheng)常使用(yong)。
