Its name is "FlashTorch Mini".
You can choose from three levels of light brightness, usually designed as a flashlight that illuminates a dark place, such as in case of a disaster it can be used as a heat source for simple cooking or raising a fire.
With the heat of a powerful halogen light of 2300 lumens, it is possible to light a fire in a few seconds if it is thin paper and so on. It seems that the usable time at the maximum power that can cause fire can be around 30 minutes, so the battery pack and the charger are in a set. It is safe to worry about powerfully, but it seems that you are also careful about safety devices so that it is equipped with a mode that allows you to switch off automatically, or that you do not light accidentally. The price is $ 199 (about 20,000 yen) and the shipping fee is slightly higher at 25 dollars, but if you prepare one, it seems to be an encouraging ally at disaster.
