OTG USB HUB with charger

[the_hatrix]

Hi,

In order to make my tab as a laptop replacement, I want to connect it to an external HD plus charging the tab at the same time.

I am looking at this: http://www.ebay.ca/itm/7-1-Card-Card-Reader-USB-HUB-Combo-Connection-Kit-SAMSUNG-Galaxy-Tab-/180767619221?pt=US_Memory_Card_Readers_Adapters&hash=item2a1696f895

Now I guess I will separate my questions to make it easier to understand (in all cases, assume that there is external power plugged into the hub already):
1) with nothing plugged into the hub, will it power my tab?
2) with an external HD plugged in without another power source for the HD, will the HD work and will the hub still power my tab?
3) with an external HD plugged in with another power source for the HD (let's say Y cable where the second usb cord goes to a power source), will the HD work and will the hub still power my tab?

Thanks

I think the best way to find out is to buy it and find out, dude. It's only $5...

I havnt tried that exact "dock" but im using a dock with only a mini hdmi output and a charge input, my hdmi only works if the charger is connected, otherwise its just a black screen... Dont know if its the same with that dock you want but i think it is, the tab is manufactured to need the powersource to show the pic since it needs the stronger current, correct ne if im wrong but i read this somewhere in the forum about the galaxy sIII
