Careful with metal: a Steam Controller nearly caught fire due to a watch

Published on May 23, 2026 | Translated from Spanish

A Steam Controller user experienced a tense moment when their controller started sparking during charging. The culprit was their smartwatch: the metal strap touched the exposed pins of the dock, causing a short circuit. Although the affected user admits their mistake, others recalled that Valve's manual already warns about the internal magnet in the dock and the risk of attracting metal objects.

Steam Controller charging dock with exposed metal pins, smartwatch with metal strap accidentally falling onto the contacts, visible electrical sparks during the short circuit, thin smoke rising from the contact point, partially disassembled controller showing internal circuits and battery components, dark background with dramatic technical workshop lighting, photorealistic cinematic style, sharp focus on the short circuit area, reflective metal textures, high electrical tension atmosphere

The dock design: a magnet that doesn't forgive ⚡

Valve included a magnet in the Steam Controller charging dock to facilitate docking, but this technical decision has a side effect: it attracts any nearby metal object. In this case, the watch strap made direct contact with the charging pins, closing the circuit. The lack of an insulating protector or a design that covers the exposed contacts turns a useful accessory into a potential risk if the area is not checked before connecting.

The watch that almost left you without a controller (and without a home) 🔥

Apparently, the real enemy of the Steam Controller isn't poorly optimized games, but your own watch. Who would have thought that the accessory you use to track your steps could turn your desk into a sci-fi scene with sparks included. Good thing the user reacted in time; otherwise, the story would be about how a Valve controller ended up toasting not only its battery but also your favorite wrist.
