Various example embodiments are disclosed. According to an example embodiment, a lockable power cord may include a power module, a locking member, a power cord, a power supply, and a loop. The locking member may include at least one arm member biased radially outward from the power module to an expanded state. The locking member may be configured to move radially inward toward the power module in response to the power module entering into the power receptacle, and expand radially away from the power module into a locking cavity of the power receptacle when the power module enters beyond a locking point within the power receptacle. The loop may include at least a first opening having a width smaller than a width of the power supply.
