Handwarmers S06E01 Jon-e Giant catalyst & springs
Channel: Mountain Parameters
Date: 08/02/2022

The easiest way to hold replacement catalyst in a handwarmer rebuild project is through the use of springs.

The amount of catalyst that a handwarmer holds determines the amount of heat output. This relationship is limited by the spring size, and has led to the availability of bespoke springs for the Jon-e Giant that have a larger diameter than the standard springs. However, while preferable, the use of a specialized spring is not your only option to expand the potential heat output of a Jon-e Giant. If you have a Jon-e Giant in your handwarmer quiver, but none of the specialized springs, you may still be able to increase your heat output through the use of standard springs, as illustrated in this demonstration.
