Charlotte Premium Outlets located just off of 485 is super-easy to get to with plenty of parking. There's a large number of outlets that aren't available anywhere else near Charlotte - so, that's a plus. I didn't feel like the deals were amazing - but, for the type of store you are shopping, I suppose you could feel like you're getting a deal.
The walkways between stores are outside - so, remember to bring sunglasses/coat/umbrella depending on the weather.
There are only 3 restaurants in the food court and 3 fast food options on the exit. Lesson learned - eat before you go.
There's no parking behind the mall - don't bother driving behind, it's just staff parking and no public entrances.
Check out the map before you start browsing - the layout is not intuitive.
