Power Attack and Lunge

[Kingheartsknight]

Can Power Attack be combined with other Fighter Feats such as Lunge.

Power Attack is a two action maneuver

Lunge is a one action maneuver

Can i power attack while doing a Lunge?

No. Even they both involve making a subordinate Strike, they are each their own distinct action and may not be combined

Subordinate Actions, CR 462 wrote:

Using an activity is not the same as using any of its subordinate actions. For example, the quickened condition you get from the haste spell lets you spend an extra action each turn to Stride or Strike, but you couldn’t use the extra action for an activity that includes a Stride or Strike. As another example, if you used an action that specified, “If the next action you use is a Strike,” an activity that includes a Strike wouldn’t count, because the next thing you are doing is starting an activity, not using the Strike basic action.

So when Power Attack and Lunge each tells you to "make a Strike", they don't mean "perform an activity that includes a Strike", they mean just the Strike basic action, which is then modified in the way detailed by Power Attack or Lunge
