大多数Android设备都有一个端口,用于连接到计算机(USB)和充电。我必须使用这个OTG小电缆来传输数据,还要使用真正的键盘。但是,当我连接键盘时,我无法在我工作的时候给我的设备充电。由于它们都使用相同的端口,因此有没有办法拆分OTG电缆以引入电源,但保持现有端口,以便我可以连接键盘?

Most Android devices have a single port for both connecting to the computer (USB) and charging. I have to use this OTG small cable to transfer data, but also to use a real keyboard. However, when I connect the keyboard, I cannot recharge my device while I work. Since they both use the same port, is there a way to split an OTG cable to introduce power on it, but keep the existing port so I can connect a keyboard ?
是的,至少技术上是可能的。你需要的是一个带有电源的电缆,它是一个带有雄性微型电缆的双母电缆,女性微型(仅具有电源和接地,没有数据)和女性A,如<一个href ="https://rads.stackoverflow.com/amzn/click/com/b009ymyorm" rel ="nofollow noreferrer" >这个。
此外,您还需要软件支持。我知道一个适当的内核补丁在Nexus 7上可用于cm10(这里),但我不知道任何其他设备。
Yes, it is possible, at least technically. What you need is a cable called a OTG host cable with power, which is a double-female cable with a male micro, a female micro (which only has the power and ground connected, no data), and a female A, like this one.
Additionally, you also need software support. I know an appropriate kernel patch is available for CM10 on the Nexus 7 (here), but I don't know about any other devices.
是可能的,一些手机支持电池充电规范1.2并可以利用 usb aca < / a>(附件充电适配器)同时支持OTG +充电。 (ACASIS H027是一个这样的适配器)
我的手机(摩托罗拉Moto G XT1032)无法从框中自动检测这样的适配器,但是在修改内核,我能够为它充电并同时使用USB闪存驱动器+ USB以太网。
It's possible, some phones support Battery Charging Specification 1.2 and can utilize USB ACA (Accessory charging adaptor) which support OTG + Charging at the same time. (the Acasis H027 is one such adaptor)
My phone (Motorola Moto G XT1032) is not able to auto-detect such an adaptor out of the box, but after modifying the kernel, I was able to charge it and use USB Flash Drive + USB Ethernet at the same time.
