Wolves paid the price for another lacklustre second-half performance as Championship rivals Charlton fought back to claim a point at Molineux.
Impressive Frenchman Bakary Sako fired Wolves into a fully deserved half-time lead with his fifth goal of the season.
But Lawrie Wilson pounced after the break to earn a point for Charlton.
The home side surrendered a half-time lead against Bolton on Tuesday and another flat second-half display was capitalised on by the improved Addicks.
Wilson's leveller, his first for the club since a summer move from Stevenage, came just minutes after Wolves striker Kevin Doyle saw a goal ruled out for offside.
On-loan Queens Park Rangers striker Rob Hulse hit the post before Wilson slotted in the rebound for Charlton's equaliser.
Hulse had two chances to earn all three points for Charlton when he forced a parried save from Wolves keeper Carl Ikeme before planting wide a header in the final minute.
It leaves eighth-placed Wolves, who could have moved into the play-off spots with victory, with one win from their last five league matches.
Last year's League One champions Charlton are only two points clear of the drop-zone after just one victory in their previous six games.
