Cameron Stewart’s blistering debut strike proved academic as Charlton were beaten by familiar foes Huddersfield on Tuesday.
The substitute cracked home a terrific shot from 25 yards 11 minutes after entering the fray, but the Terriers held firm for a second win against the Addicks at the John Smith’s Stadium in three weeks.
In the fourth meeting between the sides in 2013 goals either side of the break from James Vaughan and Joel Lynch laid the foundations for the home side.
The former headed home in first-half stoppage time and the left wing-back doubled his side’s advantage with a scorching drive 20 minutes after the restart, three weeks after defeating Ben Hamer from similar range in a 3-2 Capital One Cup win here.
Stewart gave Charlton hope in equally spectacular fashion 11 minutes from time, but Huddersfield held firm to end the Londoners’ mini-revival.
In an opening period devoid of clear chances until stoppage time, it was Huddersfield that claimed the lead with their first shot on target.
And the manner of the goal would have displeased Powell immensely, given it happened 90 seconds into the two minutes of stoppage time at the end of the half.
Hamer had not been forced into a save in the opening 45 minutes, but was beaten as the striker rose to head home a cross from Hammill.
Charlton had registered the sole effort on target before that as ex-Terrier Simon Church’s header from a Rhoys Wiggins centre was saved low by Alex Smithies.
Other than that there was little to seriously trouble the respective keepers as the sides, adopting identical 3-5-2 formations, tapped at the door rather than hammering it down.
Perhaps Huddersfield’s knocks were a little louder, and Vaughan made his mark seconds before the break from close range.
Lynch then took aim from way out 20 minutes after the restart and his stupendous drive flew past the grasp of Hamer and into the top right corner of the net.
While Hamer had been beaten by a skidding drive in the Capital One League Cup, this time he was floundering as the top of the net rippled and the left wing-back rightly took a bow.
An uphill task had become even steeper for the Londoners as they sought to extend their recent unbeaten run.
But substitute Stewart’s second noteworthy contribution since entering the field as a substitute hauled Charlton back in it.
His first had been to angrily confront the assistant referee after not getting a foul he deserved on the right, but having switched to the left he enjoyed much better luck.
Collecting the ball and ducking inside he cracked home a terrific drive from range to give his side a glimmer of hope.
The visitors were certainly the better side as the seconds ticked down and late claims for a penalty after a Dale Stephens drive flew behind were turned down.
But the clock was always against them as they suffered defeat for the odd goal for the fourth time this term.
There was no Yann Kermorgant in the Addicks starting XI with an ankle injury picked up in the weekend draw at Watford ruling him out.
Powell plumped for Marvin Sordell ahead of Joe Pigott to partner ex-Terriers loan man Simon Church up front.
Sordell netted at the John Smith’s Stadium three weeks ago in the Capital One Cup and got the nod to form a new-look strike partnership.
Elsewhere, the Addicks remained unchanged with Chris Solly and Leon Cort also remaining on the sidelines and Callum Harriott returned to the bench.
Ben Hamer continued between the posts for the visitors with Michael Morrison, Dorian Dervite and Richard Wood the three man central defensive unit.
Lawrie Wilson and Wiggins supplied the width with Johnnie Jackson, Bradley Pritchard and Stephens, who was also on target in the narrow 3-2 cup loss, in central midfield and Sordell and Church up top.
Harriott was joined on the bench by Bern Alnwick, Cedric Evina, Jordan Cousins, Stewart and Pigott.
The hosts pitched in the free-scoring Vaughan up front and he was partnered by Jon Stead with birthday boy Sean Scannell, 23 on the day, an attacking outlet from midfield.
Hesitant defending from the visitors let in Stead for the opening chance of the game in the third minute but the striker skewed off target after jinking inside.
The Addicks probed after that, without really troubling Alex Smithies, and 17 minutes had passed before Scannell chested down and lashed a shot wide for the hosts.
Teasing crosses from first Jackson and then Wiggins were hacked clear by the home rearguard and at the other end a Stead centre skimmed off the head of Pritchard and sailed behind for a home corner.
The lively Scannell was again off target after a jinking burst from the left and with crosses from both sides appearing the best route towards goal in the early stages Hamer claimed a clipped Hammill centre from the Terriers’ next raid.
There was a heart-stopping moment for Dervite as the clock ticked on to 32, the Frenchman bundling over Vaughan as he barrelled down the middle.
Wood was covering round from the left and his presence meant Stuart Attwell produced just a yellow card.
Hammill’s subsequent free-kick clipped the wall and dropped behind as the danger averted and a meaty Morrison challenge thwarted Scannell soon afterwards after the midfielder surged to the edge of the box.
Charlton’s first effort on goal of the half came in added time at the end of the opening period with Wiggins’ cross met with a firm header from Church, but Smithies saved low.
But in the second added minute the hosts hit the front through Vaughan – and predictably it came from a cross.
Hammill was the provider from the right, floating the ball into the dangerzone and Vaughan rose well to glance a header beyind Hamer and inside the left post and in.
There was scarcely time to restart before the teams retreated, Powell’s team-talk decidedly different that it would have been.
Soon after the restart a clipped ball found Sordell in space on the left but in opting to volley first time he could only sky a shot high over the bar. In hindsight he might have taken a touch.
Jonathan Hogg pulled up injured for the hosts soon after that and was unable to continue as his side soldiered in with 10 men as Oscar Gobern patiently waited on the sidelines.
The switch was made on 50 minutes and Church was booked for simulation soon afterwards after going down under pressure from Clarke.
Jackson thrust his firsts in frustration after his drive cannoned off an unwitting Sordell and Stead drove wide after a rapid break from the hosts saw Vaughan peel into space down the right channel.
Powell was preparing to make a change when the hosts doubled their lead in spectacular fashion.
Lynch was on target for the second successive game against the Addicks with a magnificent effort from range.
Collecting the ball way out on the left, he advanced inside and let fly with a venomous 30-yard effort that ripped past Hamer and into the top right corner of the net.
Soon after the restart Stewart and Harriott entered the fray, the former for a debut with Wood and Sordell leaving the action.
Pritchard’s low drive was claimed at the second attempt by Smithies and the midfielder looped a header onto the roof of the net from a Wilson centre moments later.
The dynamic of the game changed 11 minutes from time, however, as Stewart opened his Charlton account in fabulous fashion.
Like Lynch earlier in the half, he collected the ball on the left side and unleashed a magnificent drive that flew past Smithies and into the top corner of the net.
It was a goal out of the blue, and suddenly there was hope for the men in all red.
Pigott came on for skipper Jackson as Powell rolled the dice one last time and home sub Oliver Norwood flung himself in the way of a Stephens drive at the start of five added minutes, sending the ball behind for a corner.
The midfielder was booked for a foul on Vaughan moments later and another good block from the hosts kept out a Pigott drive from the edge of the box in the third added minute.
A rugby tackle more akin to the Huddersfield Giants saw Adam Clayton booked for stopping Harriott in full flow, and from the free-kick penalty claims were turned down after a shot from Stephens was blocked behind.
Hamer came up for the corner and dived in amongst the boots, but the clock was against the Londoners as the home side celebrated three hard-fought points moments later.
