Find a compatible replacement for your Steam Deck charger.
It's not about personal preference for the charger itself, but the connection method matters. The loose cable could cause issues, so upgrading to a 45-65W or even 90-100W charger would be safer. Battery performance isn't directly tied to wattage alone; it depends on how well the device manages its power draw. Most modern devices limit their output based on battery health and safety, not just advertised wattage. The Steam Deck likely has built-in safeguards to prevent over-draining or overheating, regardless of the charger's specs.
Check if the cable end is broken and determine whether the deck socket is loose or damaged.
The device will always take only what it requires. A larger wattage brick won’t heat up as much compared to one with just the power your Steam deck needs. The issue is that your Steam Deck charges at a specific voltage (listed on the charger), and a higher wattage brick must support that voltage, provide enough current then, and still communicate properly. Yes, you can use a higher wattage charger, but it may charge slower. The main reason battery health drops during charging is overheating. TLDR: Check your charger’s specs (voltage and amps it handles) and choose one that matches those limits
