When the power goes out or you are miles from the nearest kettle, having a reliable way to boil water and cook a hot meal matters enormously. A portable camping gas stove burning a butane or propane canister is the workhorse: it lights instantly, throws out serious heat and will bring a litre of water to the boil in three to five minutes. Solid fuel tablets, often called hexamine or Esbit, sit at the opposite end. They are tiny, weigh almost nothing and simply need a match, but they burn slowly and are really only suited to boiling rather than proper cooking.
For UK preparedness the two are not really rivals; most sensible preppers keep both. A camping stove handles everyday power-cut cooking and camping, while a strip of solid fuel tablets lives in the bug-out bag or car as a foolproof failsafe that never leaks, never runs flat and stores for years. Price bands are modest either way: a decent single-burner stove runs roughly fifteen to forty pounds plus canisters, whereas a box of tablets costs only a few pounds. Crucially, both burn fuel and give off carbon monoxide, so both must only ever be used outdoors or in genuinely open, well-ventilated spaces.
| Feature | Portable Stove | Solid Fuel Tablets |
|---|---|---|
| Boil speed and heat output | Strong, adjustable flame; boils a litre in roughly three to five minutes and simmers for real cooking. | Low, steady heat; a single tablet takes eight to twelve minutes to boil a mug and cannot be turned down. |
| Weight and pack size | Bulkier; the burner plus a gas canister adds noticeable weight and takes up room in a pack. | Featherlight and flat; a box of tablets and a folding stand slip into a pocket or bug-out bag. |
| Fuel cost and storage | Canisters cost a few pounds each, need care in storage and can slowly lose pressure or run empty. | Very cheap per tablet, shelf-stable for years, no leaks or pressure loss, easy to stockpile. |
| Reliability and simplicity | Reliable but has valves, seals and ignition that can fail; struggles in extreme cold with butane. | Almost foolproof; light with a match or spark, nothing to break, works when everything else fails. |
| Cooking versus boiling only | True cooking: fry, simmer and boil, so you can prepare proper meals for a household. | Boiling only in practice; fine for hot drinks, rehydrating rations and warming tinned food. |
| Smell and residue | Clean-burning gas with little odour or residue and no sticky marks on your pans. | Noticeable fishy smell and a sooty, tarry residue that can stain pans and needs scrubbing. |
| Best use and price band | Primary cooker for power cuts and camping; around fifteen to forty pounds plus canisters. | Ultralight emergency backup for the grab bag or car; only a few pounds per box. |
Choose a camping gas stove when it will be your main way of cooking during a power cut or a camping trip, and when you want more than just boiled water. The fast, adjustable flame lets you brew tea in minutes, simmer a stew and feed a whole household properly. It is the better everyday tool if you have the space to store canisters safely and will use it regularly. Keep a spare canister or two in reserve, remember butane weakens in the cold, and always cook outdoors or in a fully ventilated space.
Choose solid fuel tablets when weight, simplicity and long-term storage matter most, or when you want a cheap failsafe alongside your main stove. They are ideal for a bug-out bag, a car kit or a coat pocket, since they never leak, never lose pressure and store for years. If your gas runs out or your stove fails, a single match and a tablet will still boil enough water for a hot drink or a ration pack. Accept the slow boil, the smell and the sooty residue, and only ever burn them outdoors.
These two options complement each other rather than compete. A camping gas stove is the better primary cooker: fast, powerful and capable of real meals, making it the sensible everyday choice for power cuts and camping. Solid fuel tablets are the ultralight, dependable backup that boils water when nothing else will. The pragmatic answer for most UK preppers is to keep both, with the stove as primary and tablets as the failsafe. Whichever you use, remember that both burn fuel and produce carbon monoxide, so they must only ever be used outdoors or in genuinely well-ventilated spaces, never inside a home, tent or garage.
