隨著全球濟(ji)濟(ji)的(de)(de)(de)(de)快速發展，外出(chu)旅(lv)游的(de)(de)(de)(de)人越來越多(duo)，隨身攜帶式(shi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子產品也越來越多(duo)，如(ru)手機(ji)(ji)、數(shu)碼相機(ji)(ji)、mp4、GPS等，都(dou)是要(yao)用(yong)(yong)到(dao)電(dian)(dian)(dian)(dian)(dian)池，但這些(xie)設備的(de)(de)(de)(de)隨機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)池都(dou)會因(yin)為電(dian)(dian)(dian)(dian)(dian)池容量低而顯得不能(neng)滿足設備的(de)(de)(de)(de)正常(chang)使用(yong)(yong)時間(jian)，但旅(lv)行(xing)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)出(chu)現卻很好的(de)(de)(de)(de)解(jie)決了這個問題。旅(lv)行(xing)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)，英文名(ming)稱(cheng)Charger,通常(chang)指的(de)(de)(de)(de)是專為蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)裝置提(ti)供能(neng)量的(de)(de)(de)(de)設備。充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)主要(yao)是采用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子半導(dao)體(ti)器(qi)件，將電(dian)(dian)(dian)(dian)(dian)壓和頻率(lv)固定不變(bian)的(de)(de)(de)(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)變(bian)換為直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)一種靜(jing)止變(bian)流(liu)裝置。在(zai)以蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池為工作電(dian)(dian)(dian)(dian)(dian)源或備用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)(de)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)場合，現在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)具(ju)有廣泛的(de)(de)(de)(de)應用(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(deng),也叫(jiao)“外掛電池”，移動電源(yuan)充(chong)(chong)電器是(shi)隨著目前(qian)數(shu)碼產(chan)品的(de)(de)(de)普及和快(kuai)速(su)增長而發展起來的(de)(de)(de)，其定義就是(shi)方(fang)便易攜帶的(de)(de)(de)大容量隨身電源(yuan)。擁有該(gai)充(chong)(chong)電器，就可以在移動狀態中隨時(shi)隨地為多種數(shu)碼產(chan)品提供(gong)電能(供(gong)電或(huo)充(chong)(chong)電)。

　　蓄電池等電池充電器主要(yao)是靠貯存化(hua)(hua)學能量，于(yu)必要(yao)時放出電(dian)(dian)能的(de)一種(zhong)電(dian)(dian)氣化(hua)(hua)學設備。該(gai)電(dian)(dian)池主要(yao)是通過鉛(qian)蓄電(dian)(dian)池內的(de)陽(yang)極(PbO2)及陰(yin)極(Pb)浸到電(dian)(dian)解

液(ye)(稀(xi)硫酸)中，兩極間產生(sheng)2V的電(dian)力來實(shi)現充(chong)放電(dian)等功能，形狀大小上不同(tong)，而且有些不能直接(jie)的使用(yong)第二次(ci)。

　　車充(chong)(chong)，又(you)稱為(wei)(wei)車載充(chong)(chong)電(dian)器(qi)是為(wei)(wei)了(le)方便車主旅游時(shi)用(yong)車載電(dian)源隨時(shi)隨地(di)為(wei)(wei)數碼產品充(chong)(chong)電(dian)的配(pei)件。目前部分高端車載充(chong)(chong)電(dian)器(qi)一般(ban)包括2個(ge)USB接(jie)口，可同(tong)時(shi)為(wei)(wei)

  

 

兩臺數碼產(chan)品(pin)充電。這類(lei)產(chan)品(pin)一(yi)般具有過載(zai)保(bao)護(hu)(hu)，短路保(bao)護(hu)(hu)，高(gao)壓(ya)輸入保(bao)護(hu)(hu)，高(gao)溫(wen)保(bao)護(hu)(hu)，四重(zhong)安全(quan)保(bao)護(hu)(hu)功能(neng)(neng)，確保(bao)能(neng)(neng)安全(quan)使用。車(che)載(zai)充電器在車(che)用的同(tong)時，也(ye)能(neng)(neng)家用，實現(xian)車(che)充、直充、USB充三(san)合一(yi)多功能(neng)(neng)用途

旅行充(chong)電(dian)器(qi)注意事項

　　1）、旅行充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)在(zai)給手機電(dian)(dian)(dian)(dian)池的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)過程中要注意電(dian)(dian)(dian)(dian)源(yuan)的(de)輸出電(dian)(dian)(dian)(dian)壓必須(xu)要在(zai)規定能夠的(de)范(fan)圍內，否(fou)則實現(xian)不了充(chong)(chong)電(dian)(dian)(dian)(dian)功(gong)能。

　　2）、要保(bao)持充電器干燥，因為雨水、濕氣和各(ge)種液體或水分都有(you)可能含有(you)礦物質，會(hui)腐蝕電子元件和線路。

　　3）、不要放在高溫處。高溫將縮短電(dian)子裝置的壽命、損壞電(dian)池并使某些塑料老化。

　　4）、在(zai)購買(mai)旅行充(chong)(chong)電器時最好到(dao)廠(chang)家授權的專營店(柜)購買(mai)，這樣可保(bao)證買(mai)到(dao)品(pin)質正(zheng)宗的原裝配(pei)件(jian)。因隨便(bian)的選(xuan)用，可能會使(shi)被充(chong)(chong)的電器達(da)不到(dao)最佳使(shi)用狀(zhuang)態，嚴重者(zhe)甚(shen)至影響(xiang)其正(zheng)常(chang)使(shi)用。
