I generally light charcoal with a propane weed burner. I learned this watching Jiarby light up at a competition long ago, with a rig that crossed Ghostbusters with Commando.
If propane isn't doing it for people, try MAPP gas. It burns hotter. For sweating copper pipes, it's like landing a jet rather than a prop plane. I don't get enough practice (I'm a dilettante at every handyman skill) so I stick to propane, which works well enough on every Fogo charcoal I've tried.
As I learned from Dennis, fires need air more than heat, once they're lit. There's the trusty hair dryer. I prefer a leaf blower. You could need goggles; what's that barbecue saying?
