Chadwick has joined the Rocks on dual terms with Worthing and his strike gave them an interval lead. But Archie Willcox levelled for the Hampshire side on 70 minutes and Reuben Austin nicked the winner seven minutes into time added on.
It was revenge for Portchester, who’d lost 5-4 at home to Bognor in a remarkable opening day game.
The result leaves Jamie Howell’s side down to 12th in the Isthmian south central table. They visit old rivals Met Police next Saturday.
