Overview
Backyard patios get charcoal flavor with gas-like convenience from the Masterbuilt AutoIgnite: press a button to light the fire starter, then set a temperature on the panel or app. A digital fan feeds air to hold that heat for smoking or searing.
Hands-off temperature control turns charcoal cooking into a set-and-check job, from low smokes to hot sears. A small hopper means overnight cooks need a refill partway through.
Who it's for
Home cooks who want to smoke ribs or sear steaks on charcoal without fiddling with vents. Those running all-night brisket cooks will be refilling the hopper.
Pros and cons
- Push-button charcoal lighting
- Digital and app temperature control
- Fan holds steady heat
- Cast iron sear plate
- Small hopper for overnight cooks
- Fire starters needed each light
- Only a manual listed as included
Performance notes
The fan meters air into the charcoal bed, which governs how hot it burns and how steady the temperature stays. Hopper size sets cook time, and fuel type changes how long a load lasts.
