不(bu)(bu)同品牌筆記本電(dian)腦電(dian)源適配器(qi)不(bu)(bu)能通用的主要原因

筆(bi)記(ji)本(ben)電(dian)(dian)腦(nao)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)并不(bu)通用(yong)大(da)家(jia)是(shi)(shi)否遇到過這(zhe)種(zhong)情(qing)況？在某些場(chang)合突(tu)然(ran)筆(bi)記(ji)本(ben)電(dian)(dian)腦(nao)電(dian)(dian)池供電(dian)(dian)不(bu)足，又沒有(you)(you)(you)帶電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)，工作還有(you)(you)(you)一點點沒有(you)(you)(you)完成(cheng)，這(zhe)種(zhong)情(qing)況非(fei)常令人焦慮和尷(gan)尬。有(you)(you)(you)些朋友在這(zhe)個時(shi)候可(ke)能(neng)試圖借(jie)用(yong)他人筆(bi)記(ji)本(ben)電(dian)(dian)腦(nao)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)，可(ke)是(shi)(shi)大(da)家(jia)要注意了，不(bu)同品牌筆(bi)記(ji)本(ben)電(dian)(dian)腦(nao)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)是(shi)(shi)不(bu)能(neng)通用(yong)的，至少目前是(shi)(shi)這(zhe)樣。

不同品牌筆記本電腦電源適(shi)配器不能通用的主要原因有(you)三：

一、接口不同

多數筆(bi)記(ji)本(ben)電(dian)腦(nao)電(dian)源適配(pei)器(qi)品牌間的(de)接(jie)口(kou)(kou)不(bu)同(tong)，這就(jiu)意味著使用其他品牌的(de)電(dian)源適配(pei)器(qi)根(gen)本(ben)不(bu)能插入到你的(de)筆(bi)記(ji)本(ben)電(dian)腦(nao)進行供(gong)電(dian)。接(jie)口(kou)(kou)不(bu)同(tong)是(shi)相對安全的(de)，因(yin)為至少你不(bu)會插入電(dian)流或電(dian)壓不(bu)符合的(de)電(dian)源適配(pei)器(qi)給筆(bi)記(ji)本(ben)電(dian)腦(nao)供(gong)電(dian)，而導(dao)致電(dian)腦(nao)硬件損壞。

二、電壓不同

不(bu)同(tong)品牌筆(bi)記(ji)本(ben)電(dian)(dian)腦電(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)電(dian)(dian)壓是不(bu)相(xiang)同(tong)的，例(li)如：一般(ban)情況下(xia)IBM是16V，Dell是20V，Hp是18.5V，Sony是19.5V等。由此可見(jian)，即便電(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)接口相(xiang)同(tong)，也不(bu)能使用不(bu)同(tong)品牌的筆(bi)記(ji)本(ben)電(dian)(dian)腦電(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)進行供電(dian)(dian)。

三、電流不同

不(bu)同品牌筆記本電腦(nao)電源適配器電流也是不(bu)相同的，例如(ru)：一般(ban)情(qing)況下IBM是4.5A，Dell是3.34A，Hp是2.7A，Sony是4.1A等。

其實(shi)，相同(tong)品(pin)牌(pai)筆(bi)記(ji)本電(dian)(dian)腦電(dian)(dian)源適配(pei)器的電(dian)(dian)壓和(he)電(dian)(dian)流(liu)也不盡相同(tong)。所以(yi)，即便是相同(tong)品(pin)牌(pai)筆(bi)記(ji)本電(dian)(dian)腦間竄(cuan)用電(dian)(dian)源適配(pei)器也要確認電(dian)(dian)壓和(he)電(dian)(dian)流(liu)規(gui)格。
