They key point is as you said he had been using his power for a far smaller time and had yet to spend most of his power. He lost to Sauron in the battle with the Palantir, but in this battle he would have the ring strengthening him. We know he was mightier than Gandalf so stands to reason he should have been capable of what Gandalf would.
