移動(dong)電(dian)(dian)(dian)源(yuan)一(yi)(yi)(yi)種(zhong)集供電(dian)(dian)(dian)和充電(dian)(dian)(dian)功(gong)能(neng)于一(yi)(yi)(yi)體的便攜式充電(dian)(dian)(dian)器，可(ke)以給手(shou)機(ji)(ji)(ji)等(deng)數(shu)碼設備(bei)隨(sui)時(shi)隨(sui)地(di)充電(dian)(dian)(dian)或(huo)待(dai)機(ji)(ji)(ji)供電(dian)(dian)(dian)。一(yi)(yi)(yi)般(ban)由鋰電(dian)(dian)(dian)芯或(huo)者干電(dian)(dian)(dian)池(chi)作為儲電(dian)(dian)(dian)單元。區(qu)別(bie)于產(chan)品內(nei)部配置的電(dian)(dian)(dian)池(chi)，也叫外掛電(dian)(dian)(dian)池(chi)。一(yi)(yi)(yi)般(ban)配備(bei)多(duo)種(zhong)電(dian)(dian)(dian)源(yuan)轉接頭， 通常具有大容量(liang)、多(duo)用途、體積小、壽命長和安全可(ke)靠等(deng)特點，是(shi)可(ke)隨(sui)時(shi)隨(sui)地(di)為手(shou)機(ji)(ji)(ji)、MP3 、 MP4 、手(shou)機(ji)(ji)(ji)、PDA 、掌上電(dian)(dian)(dian)腦、掌上游戲機(ji)(ji)(ji)等(deng)多(duo)種(zhong)數(shu)碼產(chan)品供電(dian)(dian)(dian)或(huo)待(dai)機(ji)(ji)(ji)充電(dian)(dian)(dian)的功(gong)能(neng)產(chan)品。

移動電(dian)(dian)(dian)(dian)源(yuan)(yuan)，也叫e電(dian)(dian)(dian)(dian)源(yuan)(yuan)、“外掛電(dian)(dian)(dian)(dian)池”、“外置電(dian)(dian)(dian)(dian)池”、“后備電(dian)(dian)(dian)(dian)池”、“數碼充電(dian)(dian)(dian)(dian)伴侶”、“充電(dian)(dian)(dian)(dian)棒”、“充電(dian)(dian)(dian)(dian)寶”“續(xu)電(dian)(dian)(dian)(dian)蟲(chong)”，它還有一個(ge)非(fei)常(chang)個(ge)性的(de)(de)名稱：“手機戀(lian)人”，“續(xu)電(dian)(dian)(dian)(dian)蟲(chong)”。“移動電(dian)(dian)(dian)(dian)源(yuan)(yuan)”這(zhe)個(ge)概念是隨(sui)著目(mu)前數碼產品的(de)(de)普及和(he)快速增(zeng)長而發展起來的(de)(de)，其定義(yi)就(jiu)是方便易攜帶的(de)(de)大容量隨(sui)身電(dian)(dian)(dian)(dian)源(yuan)(yuan)。

　　目前數碼(ma)產(chan)品功能日(ri)(ri)益(yi)多樣(yang)化，使(shi)用更(geng)加頻繁(fan)，與我們(men)日(ri)(ri)常生活的(de)關聯也(ye)越來越密切，如何提高數碼(ma)產(chan)品使(shi)用時間，發揮其最(zui)大功用的(de)重(zhong)要性(xing)就更(geng)加刻不容(rong)緩。移動電(dian)源(yuan)，就是針對并解決(jue)這一問題的(de)最(zui)佳方案，隨(sui)身攜(xie)帶(dai)一個移動電(dian)源(yuan)，就可以(yi)實現于室外隨(sui)時隨(sui)地為多種數碼(ma)產(chan)品移動充電(dian)。
