[討論] USB傳輸線0.5A -> 1A
跟大家分享(討論)一下
因為MOZART跟一般的智慧型手機一樣 原廠旅充都是1A (其他智慧型手機甚至更高)
但傳輸線(USB) 標準的供電是500mA
一般來說 用傳輸線充手機會很慢
我的做法是用"隨身硬碟"專用的Y形線 (USB公*2 to miniUSB公)
再加個轉接頭換成microUSB公頭
這樣傳輸跟充電就可以兼具了
之前跟用其他智慧型手機的朋友分享過這招
但他有點疑慮 因為他的手機原廠旅充是850mA (SE ARC S)
他怕這招會不會過充之類的
我自己的經驗是還好 因為之前用過數支手機 原廠都是miniUSB 1A的供電
但我接上 HTC 的2A變壓器 照樣充電 並無異常 (有沒有特別快我就沒注意了XD)
變壓器的規格 1A跟2A 應該是供電上限 而非固定輸出此值才是
電壓才是固定5V 能吃多少電則是各個設備能吃多少各憑本事
