Valve has announced a safety concern with the Steam Puck, its magnetic charging dock for the 2026 Steam Controller. The company revealed that exposed metal pogo pins on the device output five volts even when idle. This design lacks short-circuit detection and overcurrent protection mechanisms.
Exposed pogo pins output 5V even when idle without short circuit detection or overcurrent protection mechanisms.
A user reported that a Pixel Watch 4 metal band accidentally touched these active contacts. The contact caused an immediate short circuit, producing a hissing sound and rapid heating. Both devices sustained visible burn marks on their surfaces, though neither lost functionality.
Community members have raised alarms about the potential for fire hazards given the exposed electrical components. Valve hardware engineers contacted the user who reported the incident to investigate further. The company has not yet released an official public response or a fix for the issue.
The Steam Puck serves as the primary charging accessory for Valve's latest controller lineup. This safety defect introduces unexpected risks for users placing multiple devices near the dock simultaneously.
Valve hardware team contacted the Reddit user Toikka regarding the incident, but no official public response has been released yet.
