휴대충전기의 무게와 크기에 따른 만족도 및 선호도 분석

The purpose of this study was to grasp the weight that the user satisfies according to the size of the product, targeting products that do not prefer weight. Forty college students in their 20s, whose size estimation ability was verified in this experiment, evaluated the satisfaction, preference, and expected price according to the weight and height of the portable charger, along with the weight. This study selected two types of portable chargers that do not favor weight as products to be tested, and are sold in two sizes and weights. In this experiment, a total of 10 portable chargers were prepared by having two sizes of portable chargers having five weight levels selected based on commercial weight. The experiment participants evaluated the weight of portable chargers by the modulus method, evaluated the satisfaction and preference of the portable charger weights on a 11-point semantic differentiation scale, and evaluated the expected price in raw units. As a result of the study, satisfaction and preference did not increase as the weight of the portable charger was lighter. The weight satisfaction and preference weight of the portable charger were found to be 140g, which is slightly less than the commercial weight in both sizes of portable chargers. Satisfaction and preference of portable chargers with less weights did not increase or were rather low.
