Abstract
An important aspect of objects is their perceived weight. Few studies have simultaneously considered the weight of a product and its size. The current study assessed the perception of a portable charger, for which weight was regarded as a negative element. Forty participants rated portable chargers with different weights and sizes regarding satisfaction, preference, and expected price. Ten portable chargers were prepared for the experiment, each of which had different sizes and weights. The results showed that the perceived weight of a small one was significantly higher in the same-weighted ones, while the perceived weight of a heavy one was also significantly higher in the same-sized ones. The size-weight illusion was confirmed. However, portable chargers lighter than 140 g received equal or lower satisfaction and preference ratings than the product. This tendency contrasts with the results of previous experiments in product groups in which weight acts as a positive factor. Consumers' perception of weight seems to affect satisfaction and preference. The limit weight suggested in this study could be used to determine the target weight of the product. Relevance to industryThere might be a limit to the appropriate weight among products for which weight is a negative factor. If the item is too light, this will negatively affect user perceptions.
