Co-generate with a Stirling engine or steam turbine. Your application is the wrong scope for TECs. It will be a hundred times more expensive, and a tenth of the efficiency.

Last time I was looking at efficient camp stoves I ran into this guy:

The idea of putting my phone, or any lithium battery really, that close to fire... this plan is not for me.

Couldn't you get around that with a really long USB-A-to-whatever charger cable?

Slapping a Stirling engine on a rocket stove just seems like a really good idea to me. My major concern would be the in-backpack weight and volume.

DC doesn’t like long runs, but I believe there’s a battery in that yellow block along with the charge circuitry. If I’m wrong it may warrant another look.
