The present invention discloses a portable emergency escape device comprising a casing, a drum rotatably installed inside the casing and around which a wire is wound, a reduction gear connected to the drum, a DC motor having a rotation shaft connected to the reduction gear, a safety belt worn by a user, a braking resistor for determining a descent speed, and a constant speed control unit connected to the braking resistor. The braking resistor is connected between both ends of a power input terminal of the DC motor, and the braking resistor can control a resistance value. And, the constant speed control unit changes the resistance value of the braking resistor in response to the user's weight to maintain the descent speed constant regardless of the user's weight.
