As more and more Internet of Things (IoT) technologies have been introduced to our social life, little, however, has been known regarding the potential adopters and consumers of the IoT applications. Through an online survey (N = 191), this study reveals the key role of power usage in driving adoption of the IoT. Power users are more likely to find the IoT cool, useful, easy to use, and thus acquiring stronger adoption intentions. While the high level of intelligence acquired by the IoT to automatically perform tasks without continuous human control appeals to power users, such unprecedented computer agency of the IoT technologies, on the contrary, impedes adoption of nonpower users. Power usage also moderates preferences for IoT applications of different domains (environment, city, home, human body). Theoretical and design implications are discussed.
