Tariqe Fosu scored twice as Lee Bowyer made it two wins from two games in caretaker charge of Charlton with a thumping 4-0 victory at relegation-battling Northampton.
Bowyer, placed in temporary charge last week, saw Ben Reeves hand his side an early advantage before Fosu scored either side of half-time and then Josh Magennis headed in a late fourth.
The Addicks sit two points and one place outside the play-offs, while Northampton remain third from bottom.
Chartlon were ahead after 14 minutes when Lewis Page's peach of a cross was headed in by Reeves and it was two five minutes later courtesy of Fosu, who strode through the middle of the pitch and found the bottom corner from 20 yards.
Nicky Ajose and Jake Forster-Caskey had further chances before the visitors went three ahead five minutes into the second half as Fosu scored his second, driving home from 25 yards.
Magennis added the gloss to Charlton's victory 10 minutes from time, heading in Reeves' cross at the back post.
