I've got one of these (finding dry sticks in NM isn't hard) and it cooks fast. The battery pack runs a fan that really gets the fire hot, and recharges itself from the heat. Then you can plug any USB device into it to run or charge. I wish these existed back in my college days when I fought daily battles with an Optimus white gas stove.
Just curious... by any chance, does anyone know exactly what this image is showing? Some manner of grill over a pan and a pot in the background does not exactly provide a good starting point to recognize what exactly the product is supposed to be, let alone what it is called.
