我們電(dian)(dian)(dian)腦中的USB接口(kou)使(shi)用(yong)率相(xiang)當(dang)高。大部分外設(she)都需要使(shi)用(yong)它進行(xing)接駁(bo)。當(dang)然除了數(shu)據傳輸(shu)的功能之外，USB接口(kou)也有供(gong)電(dian)(dian)(dian)能力。那么你是(shi)(shi)否想過利用(yong)USB接口(kou)的5V供(gong)電(dian)(dian)(dian)，為任何一(yi)節(jie)AA可(ke)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池進行(xing)充(chong)電(dian)(dian)(dian)呢(ni)？是(shi)(shi)的，目(mu)前(qian)就有這樣(yang)的設(she)計出爐了。當(dang)然你也可(ke)以把它看做是(shi)(shi)一(yi)種新型的存儲設(she)備，只不過它內部存儲的不是(shi)(shi)數(shu)據而是(shi)(shi)電(dian)(dian)(dian)能。
