隨著全球濟濟的(de)快速發展，外出(chu)旅(lv)游的(de)人越(yue)來越(yue)多，隨身(shen)攜帶式的(de)電(dian)(dian)(dian)(dian)(dian)子產(chan)品也越(yue)來越(yue)多，如手機(ji)、數碼相(xiang)機(ji)、mp4、GPS等，都是要用(yong)到電(dian)(dian)(dian)(dian)(dian)池，但這些(xie)設備(bei)的(de)隨機(ji)電(dian)(dian)(dian)(dian)(dian)池都會因為(wei)電(dian)(dian)(dian)(dian)(dian)池容量低而顯得不(bu)能(neng)滿(man)足設備(bei)的(de)正常使用(yong)時間，但旅(lv)行充(chong)電(dian)(dian)(dian)(dian)(dian)器的(de)出(chu)現卻很好的(de)解決了這個問(wen)題(ti)。旅(lv)行充(chong)電(dian)(dian)(dian)(dian)(dian)器，英(ying)文名(ming)稱Charger,通常指的(de)是專為(wei)蓄電(dian)(dian)(dian)(dian)(dian)裝置提供能(neng)量的(de)設備(bei)。充(chong)電(dian)(dian)(dian)(dian)(dian)器主要是采(cai)用(yong)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子半(ban)導體器件，將電(dian)(dian)(dian)(dian)(dian)壓(ya)和頻率固(gu)定不(bu)變(bian)的(de)交流電(dian)(dian)(dian)(dian)(dian)變(bian)換(huan)為(wei)直流電(dian)(dian)(dian)(dian)(dian)的(de)一種靜(jing)止變(bian)流裝置。在以蓄電(dian)(dian)(dian)(dian)(dian)池為(wei)工作電(dian)(dian)(dian)(dian)(dian)源或備(bei)用(yong)電(dian)(dian)(dian)(dian)(dian)源的(de)用(yong)電(dian)(dian)(dian)(dian)(dian)場合，現在充(chong)電(dian)(dian)(dian)(dian)(dian)器具有廣泛的(de)應用(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“外掛電池”，移動電源(yuan)充電器是(shi)隨著目前數碼產品(pin)的普及(ji)和(he)快速增長而發(fa)展起來的，其(qi)定(ding)義就是(shi)方便易攜(xie)帶的大容量隨身電源(yuan)。擁(yong)有該充電器，就可以在移動狀態中隨時(shi)隨地為(wei)多種數碼產品(pin)提供電能(neng)(供電或充電)。

　　蓄電池等電池充電器主(zhu)要是靠貯(zhu)存化(hua)學能量(liang)，于必要時放出電(dian)能的一種電(dian)氣化(hua)學設(she)備(bei)。該電(dian)池主(zhu)要是通過鉛蓄電(dian)池內的陽極(PbO2)及陰極(Pb)浸(jin)到電(dian)解

液(稀硫(liu)酸(suan))中，兩極間產生(sheng)2V的電力來(lai)實(shi)現充放(fang)電等功能，形(xing)狀大小上不同(tong)，而且有(you)些不能直接的使用第二(er)次。

　　車(che)充，又稱為(wei)車(che)載(zai)充電(dian)器是為(wei)了方便車(che)主旅游時用車(che)載(zai)電(dian)源(yuan)隨(sui)時隨(sui)地(di)為(wei)數碼產品充電(dian)的(de)配件(jian)。目(mu)前部分高端(duan)車(che)載(zai)充電(dian)器一般包括2個USB接口，可同時為(wei)

  

 

兩(liang)臺數碼產(chan)品充(chong)電(dian)。這類(lei)產(chan)品一般具有過載保(bao)護(hu)，短路保(bao)護(hu)，高壓輸入保(bao)護(hu)，高溫(wen)保(bao)護(hu)，四重(zhong)安(an)全(quan)保(bao)護(hu)功能(neng)，確保(bao)能(neng)安(an)全(quan)使用。車(che)載充(chong)電(dian)器在車(che)用的(de)同時，也能(neng)家用，實現(xian)車(che)充(chong)、直充(chong)、USB充(chong)三合一多功能(neng)用途

旅行(xing)充電器注意事項(xiang)

　　1）、旅行充(chong)電(dian)(dian)(dian)(dian)器(qi)在給手機電(dian)(dian)(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)(dian)(dian)過程中要注意電(dian)(dian)(dian)(dian)源的(de)(de)輸(shu)出電(dian)(dian)(dian)(dian)壓必(bi)須要在規定能(neng)夠的(de)(de)范圍內，否(fou)則實(shi)現(xian)不了充(chong)電(dian)(dian)(dian)(dian)功能(neng)。

　　2）、要保(bao)持充電器干燥，因為雨水、濕氣和(he)(he)各種液體或水分都(dou)有可能含有礦物質(zhi)，會(hui)腐蝕(shi)電子元件和(he)(he)線路。

　　3）、不要放(fang)在高(gao)溫處。高(gao)溫將縮短電子(zi)裝置(zhi)的壽(shou)命、損壞(huai)電池(chi)并(bing)使某些塑(su)料老(lao)化。

　　4）、在(zai)購買旅行(xing)充電器時最(zui)好到(dao)廠家授權的(de)專(zhuan)營店(柜)購買，這樣可保(bao)證買到(dao)品質正(zheng)宗(zong)的(de)原裝配件。因(yin)隨便(bian)的(de)選用，可能會使(shi)(shi)被充的(de)電器達不到(dao)最(zui)佳使(shi)(shi)用狀態(tai)，嚴重者甚至影響其正(zheng)常使(shi)(shi)用。
