You could make one of these for one side of the switch and then it'll switch the Tab to fast-charge. If you have it plugged into a 1A or greater power source, it should charge faster than just the standard usb trickle.

It will probably work, but you'll have same results (charging wise) as on normal USB. Without original Samsung cable, the tab will always open the USB connection window.
BTW; the tab will charge on any USB, even on your computer USB, only thing is it will charge slower. Also, it will state that the battery is not charging, but it will charge just fine anyways.
You may not be able to charge enough to keep the batter at 100% if you're doing some heavy processing on the Tab, but it will prolong the battery life.
I can charge the tab fine via my pc; although as you mentioned it indeed is much slower rate. I hate having to unplug from computer to power adapter when I want to get a full charge quickly; thus the switchbox idea.
I actually went ahead and order one, although different one from what I listed above. It was only $13 shipped so I figured I'd give it a shot. Also picked up a universal dock / stand. I'll post back how well it works and picts when I get it.
The battery style in stock Android looks pretty dull. It doesn’t … more
