6000 BTU/h (which may be down to burner head size). And the BTU output is greater on the Vega- 8800 BTU/h against approx. I also like the fold out canister support in the Vega for when the gas canister is inverted. While the Kovea Spider has just a few very small corrugations on the pot supports, the Optimus Vega has really good serrations throughout the support lengths. There are a couple of features on the Vega that I particularly like. The Vega also looks a tad more robust than the Alpkit and Fire Maple offerings. If I ever do wish to replace the Spider I would almost certainly look at the Optimus Vega which is very well made and a similar weight to the Spider. The Alpkit Koro and Fire Maple Blade II stoves, that provides similar capabilities to the Kovea Spider, but in a lighter package may have tempted me slightly in the past, but the Spider is such a reliable piece of kit that I see no need to save the few grams and swap out for what appear to be somewhat flimsier stoves. What will have occurred is that the Propane, and possibly Isobutane, have burnt off leaving the Butane behind still in liquid form.Įvernew 900ml pan sitting above Kovea Spider in Caldera Cone This is why you can be cooking or heating water with a normal gas stove a few degrees below freezing and it may be struggling to burn, or it may splutter, even possibly stop, despite a shake of the canister revealing that there appears to be plenty of contents. As the temperature drops still further, Isobutane will remain in liquid state and mostly only Propane will be exiting the canister in gaseous state. Isobutane and Propane however, no problem. So you can see that when the temperature starts dropping below freezing, Butane is the first of the contents to struggle. Each gas vaporises at different temperatures- Butane has to be above -0.5☌, Isobutane above -11.6☌, Propane above -41.7☌. Take a look at the side of a canister and it will tell you the exact mix of gases. This isn’t as disastrous as many may make out and there is usually a way round it. The problem with using gas stoves in the cold is the temperature at which gas in a canister vaporises. Inside these is the collapsed and coiled Kovea Spider, butane gas canister adapter, thin titanium foil windscreen, Torjet lighter and even a spare gas stove- the 25g BRS 3000-T
Lightweight DCF baggie holding Evernew 900ml pan (plus lid) with GSI mug (plus lid). But for a day hike where it is a clean canister being carried to a mid-day break and I am not bothered about packing a dirty one inside the Titan after, this is a good set-up. However I prefer to keep a potentially mucky gas canister away from the inside of my pans and almost always keep these separate within my pack. It has to be wiggled around into the one permitted orientation, but then fits easily into the old classic 128g MSR Titan Kettle with the lid clamping firmly above. I ditched both pouch and igniter ages ago as the stove folds flat enough that with the flexible feed pipe looped around it, it sits very well within my flat sipper GSI mug that nests inside my favoured backpacking pan- the 110g Evernew 900ml with lid.Ī Torjet lighter and sundries (often a small cloth to stop things rattling) sits with it, along with a butane gas canister adapter, job done.Įven though I prefer the Evernew pan, the Spider will squeeze in alongside a small gas canister in some other pots and pans from my modest selection.
The Kovea Spider weighs 173g (stove only), and is sold with a small nylon pouch and piezo igniter.
