I don't think it's a "power issue" so much as a "power absorption issue".

Since she appeared, Amara has been consuming energy and growing stronger in the process. I thought it was particularly poignant how, after the Horn of Joshua was used against her, her teleporting away used the same special effects as using the Horn on her did - right down to the hair-wind-blasting.

Assuming that we have one entity that infinitely generates energy and one entity that infinitely stores energy... well, it seems pretty clear why Chuck's participation would be downright contraproductive in battle against her. All he'd be doing would be charging her up.
