Steam Controller charging puck warning follows short circuit report from metallic watch strap

A Steam Controller owner has warned others to be careful around the controller’s charging puck after a metallic smartwatch strap accidentally touched the exposed charging contacts and caused a short circuit. The Reddit user said the strap hit the puck at the wrong angle, started sizzling, and almost caused a fire.

The incident happened while the smartwatch was being charged near the Steam Controller puck. The user later said they considered it their own fault, but the situation has still started a useful discussion about how easy it can be for metallic objects to touch exposed charging pins.

Valve warns about metallic objects, but the design may still catch some people out

Valve does mention this risk in the Steam Controller’s health and safety booklet. The warning says the wireless adapter and charging puck contain magnets, and that magnetic parts may attract metal objects. It also tells players to make sure the adapter, charging puck, and controller are free of metallic objects before connecting them.

That warning matters, but many people do not read manuals closely. Even when the owner reads it, someone else in the house may not know that a metal watch strap, jewelry, key, tool, or other small item should not be placed near the puck. That makes the issue less about one user mistake and more about how visible the risk is during normal use.

The charging puck uses exposed contacts, which makes careful placement important. The Reddit post also led to comparisons with other controller charging docks. Some players pointed out that the Xbox Elite Series 2 controller uses a similar exposed pin idea, but its charging dock has a raised ridge around the pins. That kind of physical barrier can make accidental contact harder.

Another suggestion from the discussion was a handshake system, where the puck would only send power after confirming that the controller is properly attached. That would add another layer of protection, although it may also increase cost or complexity.

This does not mean the Steam Controller is unsafe when used properly. The reported problem happened because metal touched the contacts directly, and Valve already warns against that situation. Still, the report is a useful reminder that magnetic charging accessories need a clear area around them.

For Steam Controller owners, the safest approach is simple. Keep the charging puck away from metal watch straps, rings, bracelets, keys, coins, tools, and loose cables with exposed metal parts. It is also better not to place it near other charging accessories where items can overlap by accident.

The incident comes shortly after the new Steam Controller became available, so many buyers are still learning its small details. Earlier reports focused on lighter discoveries, such as the hidden Wilhelm scream easter egg triggered through haptics. This warning is more practical and more important.

Valve has reportedly been asked for comment, but there is no response mentioned yet. Until then, the best advice is to treat the puck like any exposed contact charger: keep metal away, use a clear charging space, and do not assume the magnet will only attract the controller.
