The idea of power leveling is speed and efficiency - you may wish to obtain an addon that will show you how much experience per hour you are gaining. Common methods of power leveling include doing only those quests which are most efficient in terms of experience, and analyzing the quests in any given zone so as to do them in the most efficient order possible. Additionally, ensure your character's talent build is crafted for maximum endurance. You want as little downtime as possible.

 

Twinking is different from power leveling. A twink is usually intended to remain at its current level for an extended period of time, providing some justification for the large investment into its gear. A character being power leveled is often equipped with inexpensive gear, since the player will be planning on out leveling it quickly. Also note that power leveling is sometimes used to refer to paying someone else to level your character to 80 as fast as possible (i.e. they power level for you); a distinction used by Blizzard is to refer to the paid leveling as "power leveling service." This is against Blizzard's Terms of Service. Power leveling yourself is perfectly acceptable.

 

Once you really get into the game, you'll want to participate in some World of Warcraft power leveling, though, no matter who you are. Maybe you've heard the term power leveling and aren't sure what it is. Maybe you simply don't care - you just like running around and trying to kill goblins. Power leveling is a way to reach higher levels in a very short amount of time. For example, a quest or area or skill you want is at level 60 but you're at level 20. Using some power leveling will get you there very quickly.
