Get Civ A Laptop Charger

I am a passionate youtuber, struggling to find a job.
Just moved back home with parents after travelling almost a year alone around Australia in a volkswagen golf.
I love to make video's, i've created content on youtube since it came out, under many different names, at the moment. I'm struggling to create content.
My current laptop charger doesn't output enough power to let me render/edit. I need a good quality / original charger for my alienware 18 laptop. Get the job done and I'll make a frog wrangler part 2.
