一、usb電源適配器是什么東西
usb電源適配器是一種常用的電源適配器,就是輸出端為USB插座的電源適配器,我(wo)們(men)的手(shou)機(ji)充電器一(yi)般(ban)用的就是usb電源適(shi)配(pei)器,此外,一(yi)些(xie)usb電源適(shi)配(pei)器還能(neng)提(ti)供多個usb口,給(gei)多臺電子設備充電。
usb電(dian)(dian)源適配(pei)器(qi)的一側是電(dian)(dian)源的接(jie)入插頭(tou),另(ling)一側是usb口(kou),通過usb連接(jie)線連接(jie)電(dian)(dian)源適配(pei)器(qi)與電(dian)(dian)子(zi)產品(pin),就(jiu)能(neng)實現(xian)(xian)充電(dian)(dian)功能(neng)。現(xian)(xian)在(zai)人們使用的電(dian)(dian)子(zi)產品(pin)越(yue)來越(yue)多,手機、平板等(deng)移動設備(bei)幾乎是不(bu)可或缺的裝備(bei),充電(dian)(dian)時(shi)(shi)帶上多個電(dian)(dian)源適配(pei)器(qi)的話會(hui)非常臃(yong)腫(zhong),購(gou)買一個多口(kou)usb電(dian)(dian)源適配(pei)器(qi)就(jiu)能(neng)同時(shi)(shi)為多個設備(bei)充電(dian)(dian),非常方(fang)便(bian)。
二、usb電源適配器是充電器嗎
usb電(dian)(dian)源(yuan)適配器(qi)和我們用的手機、平板電(dian)(dian)腦等(deng)電(dian)(dian)子產品的充(chong)電(dian)(dian)器(qi)其(qi)實是一個東(dong)西(xi),它是可以充(chong)當充(chong)電(dian)(dian)器(qi)的。
由于現在的(de)手機以(yi)及其他數(shu)碼(ma)設(she)備充電(dian)(dian)(dian)和數(shu)據(ju)都采用(yong)同一(yi)的(de)usb接(jie)口,并且接(jie)口都具有(you)電(dian)(dian)(dian)源(yuan)和地線,即使不進行(xing)數(shu)據(ju)連接(jie),也能通過電(dian)(dian)(dian)源(yuan)回(hui)路充電(dian)(dian)(dian),用(yong)usb電(dian)(dian)(dian)源(yuan)適配(pei)器給(gei)電(dian)(dian)(dian)子產(chan)品充電(dian)(dian)(dian),就是把(ba)220V的(de)交流(liu)電(dian)(dian)(dian)轉換為5V的(de)直流(liu)電(dian)(dian)(dian)。
三、多口usb電源適配器好用嗎
很多(duo)朋友(you)有多(duo)臺(tai)電子設(she)備,出門需要(yao)(yao)帶上多(duo)個usb電源(yuan)適配(pei)器,非常麻煩,購(gou)買(mai)一個多(duo)口usb電源(yuan)適配(pei)器后,只需要(yao)(yao)帶上幾根usb充(chong)(chong)電線,需要(yao)(yao)充(chong)(chong)電時將它插在usb電源(yuan)適配(pei)器上即(ji)可,能同時為(wei)多(duo)種設(she)備充(chong)(chong)電,具(ju)有體積(ji)小(xiao)、易攜帶的優點,還不用因(yin)為(wei)充(chong)(chong)電時插頭互相排擠而傷腦(nao)筋,使用起來非常方便。
