A Reddit user recently shared that they nearly caused a fire with the Steam Controller charging puck after a metal watch strap accidentally touched the puck’s exposed charging contacts while it was plugged in.
The contact created a short circuit, causing heat, sparks, and some melting before the user noticed and stopped it.
Shared photos showed visible damage to both the watch strap and the charging puck.
If you use the Steam Controller puck, keep it in an open area where metal objects cannot accidentally touch it while plugged in.
