Default [Q] Please confirm have this right

Hi All,


I have instlaled my nexus 7 in my car and would like to clarify a few bits.
OK been looking at two things - Firstly - using an external drive with the Nexus 7.
From what I have read and understand I need an OTG cable.

As I would like multiple usb devices connected such as mouse, keyboard webcam usb drive etc do I then connect the OTG cable to an external USB hub in order to connect the various devices? I guess my general question is - are you able to connect multiple USB devices to the Nexus 7 via the external HUB?

I'm presuming you need atleast a 2 amp charger and does plug directly into the External hub or into the Nexus itself?

I'm sure the answers exist somewhere on this site but there is a mountain of info and some of it contradictory.

Im unable to post links to cables I would need could anyone please do that so I know exactly what to purchase - I am in the uk.

Thanks for any help.
