Bought my first machine and they sent the wrong power cord

Like the title says. I know, it's not a Hismith, but that wasn't in my budget so I opted for something cheaper. Now I was able to rig up an old laptop cord but I don't think it's giving enough power and I'm trying to figure out what kind of power cord I need. All that said I did get a refund for the whole thing so now I just want to be able to power it properly.

I did use it once to test(as it goes with new toys) and it still drove me wild, but I'd like to be able to get the full effect so I'm squirming I stead of just dripping.
