有時(shí)候筆記本電池突然供電不足需要充電才能繼續(xù)使用，但是沒有帶電源適配器，這種情況非常令人焦慮和尷尬。那么電源適配器能通用嗎?選購(gòu)時(shí)應(yīng)注意什么? </p> <p> <br /> </p> <p> 1、注意輸出的電流和電壓范圍。輸出的電流和電壓是選擇適配器的一個(gè)重要指標(biāo)，應(yīng)與需要供應(yīng)電源的電子電器產(chǎn)品要求的電流、電壓相符。若選擇電壓、電流過(guò)高，則會(huì)損壞電子電器產(chǎn)品，若選擇電壓、電流過(guò)低，則設(shè)備不能正常工作或超負(fù)荷工作而影響安全性能。 </p> <p> 2、是否有安全認(rèn)證標(biāo)志。電源適配器產(chǎn)品從設(shè)計(jì)到批量生產(chǎn)，需要經(jīng)過(guò)一系列的試驗(yàn)，驗(yàn)證其是否符合安全要求。通過(guò)我國(guó)規(guī)定的安全認(rèn)證試驗(yàn)的產(chǎn)品在銷售時(shí)會(huì)貼上“CCC”標(biāo)志。 </p> <p> 不同電源適配器品牌產(chǎn)品是不能通用的!選購(gòu)電源適配器時(shí)也需要注意很多!謹(jǐn)慎對(duì)待電器，這樣才能保證我們的安全! </p> <p> <br /> </p> <p> <br /> </p><p> 電源適配器又叫外置電源，是小型便攜式電子設(shè)備及電子電器的供電電壓變換設(shè)備，具有電壓轉(zhuǎn)換功能，其常見的產(chǎn)品名稱有電源適配器、充電器和電源供應(yīng)器等 </p> <p> 電源適配器一般由外部絕緣外殼和內(nèi)部電路器件組成，其與電網(wǎng)電源（市電）的連接方式分為插頭電源線和直插式，其中直插式電源適配器的外殼與插銷形成一體，這種形式也是目前小型便攜式電子產(chǎn)品電源適配器（充電器）中應(yīng)用zui多的情況。 </p> <p> 多年來(lái)，我國(guó)一直對(duì)信息技術(shù)設(shè)備和音視頻設(shè)備用電源適配器產(chǎn)品實(shí)施CCC強(qiáng)制性產(chǎn)品認(rèn)證管理制度，同時(shí)各級(jí)質(zhì)量監(jiān)管部門也在不斷針對(duì)電源適配器產(chǎn)品進(jìn)行監(jiān)督抽檢工作。隨著電子產(chǎn)品日益增多，電源適配器供電的應(yīng)用越發(fā)普及，已形成適用人員多樣性和使用環(huán)境多樣性的特點(diǎn)，加大了產(chǎn)品質(zhì)量安全風(fēng)險(xiǎn)程度。 </p> <p> 而且電源適配器的生產(chǎn)技術(shù)工藝雖已較為成熟，但是技術(shù)門檻不高，成本低廉，缺乏生產(chǎn)質(zhì)量保證能力的中小型企業(yè)的產(chǎn)品不斷涌入市場(chǎng)，致使產(chǎn)品質(zhì)量良莠不齊，總體抽檢不合格率較高。因此，如何提升電源適配器產(chǎn)品的質(zhì)量是我們檢驗(yàn)檢測(cè)機(jī)構(gòu)、監(jiān)管部門以及電源適配器生產(chǎn)企業(yè)，甚至是整機(jī)產(chǎn)品生產(chǎn)企業(yè)共同關(guān)注的問題。
