TechGuy_93 Exposed live pins? How did this pass QA testing? If CE wasn't a self-declared certification it surely would have failed. In this day and age a) why doesn't it have a data pin to talk between controller and charger to negotiate charging like 99% of all other modern devices. And b) why does it not just have USBC?????

It's bad enough that I'm a little sceptical if it is actually true; don't believe everything you read on the internet after all, and there are certainly plenty of people out there who would fake it either for clicks and likes or out of animosity towards Valve. It's not impossible for something to be made that badly either though, unfortunately I don't have a Steam controller or I'd test it myself. …With a voltmeter, not just by putting a random piece of metal on it, I feel I ought to stress that… Reply

ezst036 Did Tom's Hardware……… you know, a hardware testing website……….. actually test this? Or is this just I heard it on reddit so now I'm passing on the unverified information? Reply

Alpha_Lyrae I don't think they're live as exposed. Instead, they're spring loaded, so they become live once depressed (when connected to controller). Metallic watch strap. Magnetic. It depressed the pins and stuck to them, creating a short. Least, that's how I can see this happening. Reply

Notton I doubt the puck can catch fire. Melt, maybe, but 5V 1A is 5W It's not even enough to cause a spark. On the off chance the puck has no power control circuitry and you hook it up to a charger that doesn't care about what it pumps out, it's 5V 3A, or 15W. 15W could potentially melt plastic, but still won't cause a fire, unless it's dumped into a lithium battery with no battery safety circuitry. https://static0.polygonimages.com/wordpress/wp-content/uploads/2026/04/steam-controller-puck-oncontroller.jpg?q=49&fit=contain&w=4032&h=3024&dpr=2 With that said, I've noticed most other wireless game controllers with a charging dock feature 4-pins.

ekio How to create fuss out of nothing. I have devices with exposed magnetic pins and never had any problem because i don’t magnet a metal sheet on it, yeah. And if you don’t slide your hand against a knife, it won’t get cut neither…. Reply
