In some embodiments, power cable 112 includes at least one mechanism for connecting to smart outlet 120 such as USB connector 114 and smart power adapter 116. In some embodiments, smart power adapter 116 includes contraband detection components for determining whether device 110 is authorized to receive power from an outlet within the controlled environment, such as smart outlet 120. In some embodiments, within a controlled environment, authorization for receiving power is determined by comparing identification information received from device 110 with a list of authorized identifiers associated with devices that have been approved (e.g., by monitoring center 130) to receive power through an outlet within the controlled environment (e.g., smart outlet 120). In some embodiments, authorization for receiving power includes the step of transmitting the identification information to smart outlet 120 and/or monitoring center 130 and receiving a contraband response from smart outlet 120 and/or monitoring center 130. In some embodiments, the contraband response indicates whether device 110 is authorized to receive power within the controlled environment. Smart power adapter 116 includes external prongs for connecting to electrical receptacles of smart outlet 120.
