How do locker charging ports work and are they safe?

Locker charging ports are integrated USB-A, USB-C, or AC outlet strips mounted inside the locker cabinet, powered through the locker structure by a low-voltage wire run to a central power strip or building circuit. Safety features include surge protection, thermal cutoff (to prevent overheating from charging multiple devices simultaneously), and UL-listed components. The locker door does not need to be open for charging — cables from inside the locker can connect to devices left inside. Some models route cords through a small opening in the locker wall. For a bank of charging lockers, plan for one 15A circuit per 8–12 lockers. OfficeFurniture2go.com carries locker units with integrated charging — call 1-800-460-0858 for specifications.
