Everything comes from China products reviews site purchased in China
The idea is as follows: If you want to put a flash drive or a 3 g/4 g modem you use an adapter OTG. However, This enters the same connector adapter, in most cell phones or tablets, the source to recharge the battery. Wouldn't it be cool if there was a way to do both?
This could be resolved with the cable below, It has a USB input on the side. That's the idea, but it doesn't work! When the cell phone between in OTG it automatically halts the charge.
The cable is cute, and lights red for charging and blue for OTG. Just not work both at the same time.
See below on my tablet a pendrive connected from the side.
The tablet mounts the drive via USB perfectly, but loses the connection when you fit the other side at source to recharge the tablet.
Although it has not worked as I wanted to, is working. I leave the link to the DealExtreme:
Good afternoon,
Have you tried connecting a USB HUB with external power supply directly to the OTG cable? I was thinking about this alternative
Should not work. I think the OTG option (indicated by a short circuit in a connector pin) modify the phone to feed an external device, and no longer receive power to recharge the battery. I don't think it will work in any case, only Tablet that have separate load DC input usb.
