If it's not infinite, it can run out. Otherwise, he'd just grab a vessel, pour all his power into it for a long time, and throw it at Amara like a grenade.

As for Chuck having to will his power into an object for it to become a Hand of God, how else do you explain the fact that Sam and Dean didn't die in Chuck's home, where they touched many things he'd touched, the angels (again) not sensing any power emanating from the home, the Prophets (who are touched by God when they're "activated") not exhibiting any power increase (yeah, they gain some knowledge; the Rod of Aaron vaporized a demon), and so on?
