A battery-powered hand warmer that can intermittently supply power while continuing heat radiation as set forth in claim (1) of the utility model registration. (3) A battery type that can supply power intermittently while maintaining heat dissipation as described in claim (2) of the utility model registration, in which the heat storage agent is polyethylene glycol with a molecular weight that has a transformation point depending on the required temperature. A pocket hearth. (4) The heat storage agent maintains heat dissipation as described in paragraph (2) of the utility model registration claim, where the heat storage agent is polyethylene glycol that is a mixture of polyethylene glycol having multiple transformation points near the required temperature and having multiple molecular weights. A battery-powered pocket warmer that can be powered intermittently. (5) A battery-powered hand warmer capable of intermittently supplying power while maintaining heat dissipation as set forth in claim (2) of the utility model registration, wherein the heat storage agent is sodium acetate. (6) A battery-powered hand warmer capable of intermittently supplying power while continuing heat dissipation as set forth in claim (2) of the utility model registration, wherein the heat storage agent contains another agent that assists the heat storage effect. (7) The shape-retaining material is non-woven fabric, woven fabric, laminated paper, thread netting,
