Objective: This study aimed to figure out the weight that the user satisfies according to the size of products, targeting product family that users generally do not prefer heavy ones.Background: The sense of the weight of an object has been regarded as an important research topic in the perspective of perception. It is also known to be influenced by weight, size, color, and material of the object. The sense of the weight of a product can be a factor influencing affective satisfaction. However, the research regarding both the size of products and the weight of those has been still insufficient.Method: A portable charger that users generally do not prefer heavy ones was selected as a product to be tested. For the experiment, a total of ten portable chargers were prepared by allowing the selected two sizes of portable charger products to have five weight levels determined based on commercial weight. Totally forty participants in their twenties evaluated the satisfaction, preference, and sense of the weight of portable chargers of different weights and sizes.Results: The satisfied and preferred weight of the portable charger was found to be 140g, which is lighter than the commercial weight in two sizes (180g, 300g) of portable chargers. Satisfaction and preference of portable chargers lighter than 140g did not statistically higher or were rather low.Conclusion: A size-weight illusion was confirmed from the perspective of the sense of the weight of the portable charger. In addition, there can be a limit to the weight with high satisfaction and preference in products in which heaviness is not preferred, which means that if the weight is far lighter than expected, it has a negative effect.Application: The limit weight presented in this study can be used to determine the weight of the portable charger.
