I was the Pilot Flying (PF) and felt aileron control was degraded right after autopilot disengagement on final at 400 Ft AGL. Performed a go around and transferred control to the First Officer who had full control of the ailerons. Accomplished an uneventful landing. After landing; I discovered that the external battery pack that I was using to charge my iPad had become lodged between my sidestick controller and the nose wheel steering control handle; hindering full left aileron displacement. I suggest not putting the battery pack; nor anything else; in a position where this is possible.
A321 Captain experiences aileron control difficulties upon disengaging the autopilot at 400 feet on the approach and a go-around is initiated. The First Officer finds no control difficulties and the second approach is uneventful. Post flight reveals that an external battery pack is hindering full left side stick movement.
