Hi what's the different between connecting the charger directly into the wall plug or using the ac power cord?

I assume you are talking about the 2 prong click in, versus the 3 prong click in with the cable?

The difference is the 3 prong cable will be grounded, the added benefit is static electricity would be passed through it without going through the laptop's power system / circuitry.

so would you recommend using the 3 prong when possible as oppose to the two?

The difference is 4.9 feet of grounded extension cable. There's not much benefit other than that. I use them both regularly but since I got the plug bug I've mostly been using it without the extension so I can do this: http://twelvesouth.com/products/plugbug/
