[Q] How to estimate the power supply capability of my Samsung tablet through otg ？
After much hesitation about the choice for which small otg gadget , I choose this one for its slim and simple looking with a suitable price:
The following idea is how I design the use situation ： The otg is connected to my Nexus 7. And I planned to plug the Samsung Tablet to one of the four usb 3.0 port. As this is not a gadget with its own power adapter. I worried about the power supply issue. I wonder which could be the main part to supply part. Let alone to add other devices to all the usb 3.0 ports.
Is my idea a practical one ? Anybody who has a wise solution is warmly welcomed.
