Propane or charcoal for a portable grill?

Propane dominates the portable category because it lights instantly, controls heat with a knob, and doesn't require disposing of hot ash, an issue at campsites and tailgates. Charcoal portables can produce better sear flavor but add cleanup and travel-safety complications. Every grill in this roundup runs on propane (1 lb canisters or, with an adapter hose, a 20 lb tank).
