The forward, who spent an unproductive five months at Fratton Park on loan from Norwich in 2021, has signed a four-year deal with the Addicks and is Nathan Jones’ sixth signing of the summer.
The 23-year-old is also the second forward the League One side have snapped up to this week after parting company with top-scorer Alfie May, who has joined Huddersfield in a £750,000-plus move. Matty Godden has also made the move to south London, after leaving Championship Coventry for an undisclosed fee.
Charlton represents Ahadme’s sixth club, with spells at Burton (twice), Ipswich and Cambridge United following his unsuccessful loan stint at PO4 that produced one goal and 10 Blues appearances.
Ipswich surprised many by forking out a reported £300,000 for the front man in September 2022, after he bagged eight goals in 22 appearances for Burton.
