I am a little confused about the wording of this feat, and the errata does not make things any more clear.
Do you use twice your strength bonus for damage in the charge attack, or do you add twice your strength bonus to the damage in a charge attack?
For example, if you have a dwarf fighter with a STR of 18 (+4 bonus), who normally does 1d10+4 damage with his dwarven waraxe, would the power lunge do 1d10+8 damage, or 1d10+4+8?
