Conor McGrandles’ header in the third minute of time added-on early a dramatic point for the Addicks for a 2-2 scoreline on the south coast.
Abu Kamara’s stunning strike and Colby Bishop’s penalty had twice but the Blues in front, before being pegged back, but remain top of League One.
Nonetheless, there were some excellent displays amid the point – and here our our Pompey player ratings...
13. Christian Saydee - 5
(Replaced Josh Murphy on 43 mins) Tried his best to get on the ball but couldn't influence anything - and very little came off. Disappointing. Photo: Jason Brown
14. Ben Stevenson - 7
(Replaced Tom Lowery on 65 mins) One of the pick of the substitutes. Mopped up in the Blues' box a couple of times and managed to at least retain possession. Photo: Jason Brown
15. Terry Devlin - 6
(Replaced Zak Swanson on 65 mins) Another right-back outing and put in his usual energy and endeavour. Photo: Jason Brown
16. Callum Lang - 6
(Replaced Kusini Yengi on 71 mins) Gave much-needed energy and one great run saw him wriggle into the box, only to be crowded out before he could shoot. Photo: Jason Brown
