Tennis author and journalist A. Wallis Myers described Powell in his book Twenty Years of Lawn Tennis as "A sound player, using a left arm and a resourceful brain to deceive his opponent, one of the best lobbers I have ever known, an intrepid poacher and a fast sprinter.".
Powell enlisted in the Forty-Eighth Canadian Battalion of the Canadian Infantry in World War I and reached the rank of Lieutenant. He was killed in action in France during the Battle of Vimy Ridge on 28 April 1917.
