Emberlit builds pack-flat wood-burning camp stoves in the USA, and this page carries the three core models from the company that started the category. Each one slots panels together into a side-feeding firebox, runs on twigs and sticks you gather on site instead of fuel canisters, and breaks back down completely flat for the pack. The side-feed door is the design that matters: you slide long sticks in as they burn instead of constantly snapping wood to length and feeding from the top, which means a steadier flame and seconds, not minutes, spent gathering fuel.
The FireAnt is the smallest and lightest, titanium at roughly three ounces, sized for solo cooking and one-pot meals. It is the most fuel-flexible of the three: it ships with a tray that holds Esbit and solid fuel tablets, and its slots are cut to seat a Trangia or Esbit alcohol burner, so wood, gel, and alcohol are all on the table when fire rules or wet weather force a change. The trade-off is firebox size, so pair it with a cup or compact pot rather than a large kettle.
The Ultra-Lite is the full-size Original reworked in titanium, around half the weight of the stainless version while keeping the larger firebox. That bigger box accepts thicker wood and longer sticks and supports wide pots and kettles without crossbars, making it the pick for backpackers who want real cooking capacity without the stainless weight penalty.
The Original in 304 stainless is the heaviest and the most affordable, and the one to hand harder use. Stainless shrugs off the dings and rough handling of base camp and bushcraft work, holds the heaviest cookware including a Dutch oven, and delivers the full Emberlit design at the lowest entry price.
All three are designed and manufactured in the USA by Merkwares, the team that set the standard this entire stove category copied. Buying an original supports that small American operation over the offshore clones, and every Emberlit is backed by the Forever Happiness guarantee, because a stove with no moving parts is one you are not going to wear out. Note that titanium panels can take on a slight warp with use, which is normal and does not affect assembly or performance.
