The other one is as higher percentage of propane as you can find, but the proviso here is don't use the cooker/can inside anything (cabins, vans, tents) as it will be more likely to make carbon monoxide than the more cleanly burning butane filled cans and this has created dead people multiple times. Carbon monoxide is tasteless, doesn't smell and kills extremely well...
