Solo Stove Bonfire 2.0 outperforms the Ranger 2.0 on heat output and group capacity with a 19.5-inch vs 15-inch diameter while sharing the same smokeless technology per CNET and Wirecutter reviews. The Ranger wins on portability at 12.5 lbs versus 20 lbs but sacrifices burn duration and stability. Bonfire is the stronger all-around pick for most backyard users.
