Solid fuel tablets are the quiet workhorse of off-grid cooking and fire-lighting. They store for years, don't leak, aren't pressurised, and light in wind and damp when other methods sulk — which is exactly why they belong in a grab bag, a car kit and a home emergency box. On their own, a couple of blocks under a small stand will boil a mug or heat a mess tin when the mains hob is out; as a fire-starter, one block gives you a reliable, long-burning flame to get damp kindling going. They're not a replacement for a proper gas stove for cooking a family meal, but for compact, no-fuss backup heat they're hard to beat.
The choice comes down to what you're doing with them. Purpose-made ethanol-based fuel blocks burn clean and hot with very little smoke or residue, which makes them the best pick for cooking and for indoor-adjacent use in a well-ventilated space. Traditional hexamine-style tablets are the compact, cheap, long-storing option for a grab bag where you just need guaranteed heat in a tiny package. Natural wood-wool firelighters are the pick when the job is starting a stove, fire pit or wood burner rather than cooking on the fuel itself. Always burn any fuel with proper ventilation and never inside a tent or an unventilated room.
Solid fuel tablets light easily, burn hot and store for years — a compact, foolproof way to boil water or cook when there's no gas and the weather's against you.
Good tablets light readily and burn hot enough to boil water in a reasonable time. Look for reliable ignition even in cool, damp conditions.

Solid fuel keeps for years without special care, which is exactly what you want from emergency and backup fuel.
Solid fuel gives off fumes. Never use them inside a tent, car or closed room — cook outdoors or in a well-ventilated space, ideally with a CO alarm nearby.
Wind steals the heat and wastes fuel. Use a stove with a shield or improvise one so the flame actually boils your water.
