Well if fire-starting skill not for cooking, warmth, signalling, maybe ...

I would Rather Buy the Stove which Charges..dual purpose item.

Now design one that charges more, has a larger mass and can be attached to a much larger surface and Keep it Cheap in Price I would consider it. I could use on on My Firebox on My BBQ Grill The Surface can easily reach 600 and I run it over 14 hours straight many times.

 

I use Solar Rope lighting On My Canopy..Would be nice to Have an additional way to charge the batteries..Sometimes there just ain't enough Daylight in the Winter to get a Full nights charge or I get placed where I get to much shade.

 

As for Leaving the Phone at Home..Take it..just don't use it unless it is an Emergency. Sometimes a Cell phone could mean the difference between Life and Death and You will never know when you truly need it until it occurs.

"just don't use it unless it is an Emergency."

I'm good with this. No need for a charger in that case. Right now, multiple weeks off the grid sound really good to me.
