Camping

[esetest]

If that's all you're doing, a canister should last easily a week. Some stoves use gas quicker than others, and of course it depends on how you set the flame too, but yes, easily a week for just a couple of brews a day. As mentioned above, use a heat/wind shield to make it go further. But I usually carry 2 canisters just in case, replace one as you use one, and never been caught out that way.

Thanks for advice Nick , I will take a spare in case .
