Valve’s Steam Controller Puck Can Charge Metal Watch Straps, With Dramatic Results
▼ Summary
– A Reddit user reported that their Steam Controller charging Puck, which has always-live exposed contacts, short-circuited against their metallic watch strap, scorching both items.
– The Steam Hardware team contacted the user to offer a replacement Puck and to investigate the incident; neither device was permanently damaged.
– The article suggests the Puck may be designed to always provide current, and a possible fix could require it to detect a connected Steam Controller before charging.
– As a precaution, users are advised to keep the Puck away from other chargers and conductive objects while it is plugged in.
– The incident raises the question of whether this hazard should have been identified before the product launched.
If you own a Valve Steam Controller and also wear a metallic watch strap, you may want to keep them far apart while charging. The Puck , the controller’s charging accessory , has exposed contacts that remain live at all times. That means accidental contact with a conductive metal surface, like a watch band, can cause a sudden, serious electrical discharge.
That’s exactly what happened to Reddit user /u/Toikka, who shared the scorched aftermath on the /r/SteamController subreddit. They were charging a Pixel Watch 4 fitted with a popular third-party metal wrist strap in the same area where their Steam Controller was also plugged in. When the watch strap brushed against the Puck, both components were visibly burned on contact.
Fortunately, no one was injured, and neither the Puck nor the smartwatch was permanently damaged. The Steam Hardware team has already reached out to Toikka, offering a replacement Puck and requesting both the charger and the watch for further investigation. It’s a swift response, but the incident raises a broader question about product safety and design oversight.
Could the Puck be redesigned to only deliver power when securely attached to a Steam Controller? That seems unlikely without altering its core charging function. But there may be software or hardware mitigations , such as requiring a latch or sensor confirmation before current flows , that could prevent similar accidents in the future.
For now, the simplest safety precaution is to keep your Puck physically separated from other charging devices and any conductive materials while it’s plugged in. If you have a metal watch strap , and I do, for my Apple Watch , it’s worth being extra vigilant.
Was this a freak accident that slipped through testing, or a design flaw Valve should have caught before launch? We’d like to hear your take in the comments.
