A portable body warming device comprised of a housing (1), a powered blower (19), a combustion chamber (25), an activator (27), a heat exchanger (35) within the housing, a portable hydrocarbon gas fuel source (39) and a battery for powering the blower and activator. The activator initiates combustion of fuel gas in the combustion chamber, and an exhaust vent port discharges combustion byproducts from the housing to serve as the portable warmer. |
