　　六(liu)級能效AC-DC電源適配器(qi)能效等級

　　能(neng)效等(deng)級：是表示家用電器產品能(neng)效高低(di)差(cha)別的(de)一種(zhong)分級方法，按照(zhao)標準相關規定，

等級1表示產品節電已達到水平，能耗低；

等(deng)級2表示(shi)產品比較節電(dian)；

等級(ji)3表示產(chan)品能源效(xiao)率為我國市場的平(ping)均(jun)水(shui)平(ping)；

等級4表示(shi)產品能源效率低于市場平均水(shui)平；

等級5是(shi)產(chan)品市(shi)場準入指(zhi)標，低于該等級要求(qiu)的產(chan)品不允許生(sheng)產(chan)和銷售。
