Fully Charged followed up a win at Gowran Park last month when again prominent throughout to land the Ryans Cleaning Handicap Chase at Punchestown.
The 4/1 chance made most of the running but having been headed by Port Stanley after two out, rallied again on the run-in before holding the late surge of his full-brother Alfa Mix by a neck.
Port Stanley could find no extra after a mistake at the last finishing a further three-and-a-quarter lengths back in third.
Winning trainer Henry de Bromhead said, “He just lacks a bit of concentration. He’s not ungenuine at all but the blinkers have really helped him focus better.
“I’m delighted for the O’Reilly sisters (Three Swallows Partnership) and hopefully he’ll go for the Paddy Power Chase at Leopardstown over Christmas.
“He keeps galloping. He looked beaten jumping the last and fair play to Hugh he kept a little bit up his sleeve for after the last.”
