USB power pot (really!)

[Plug1n]

I'm not a camper, but this could be useful - provided there is an endless supply of firewood

Seems like it may be handy for a quick phone boost for an urgent call, but fuel use is likely to limit charging to 10 or 15 minute sessions.

Stoves with USB/power chargers have been around for a couple for a couple of years, and are readily available over here in California. Biolite are probably the best well known.
It's an interesting concept, and great for extended trips to places with firewood available.

Can't imagine that having the handles and the leads dragging across the top of the grill as per the pic would be the best set-up.

I like this idea. If you consider that the electrikery is a bi product of another activity such as cooking a meal or making a hot drink.
A Trangia  will boil a litre of water in seven minutes. For a flat battery, seven minutes will probably put 25% charge into a typical android phone. Cooking a meal would take 30 to 40 minutes, again a useful amount of charge time.
I don't like the price though!
