Many of us learn the hard way, at some point, that charger wattage matters — it’s distinctly terrible to realize your phone or laptop is only half-charged right before you need to leave somewhere. That’s especially true with Valve’s Steam Deck, which has an hours-long battery life even when it’s fully topped off.

QUICK ANSWER

Valve's bundled USB-C charger supplies 45W of power, no matter if you get an OLED or LCD Steam Deck.

Valve’s own USB-C charger supplies 45W of power, regardless of whether you have an OLED or LCD version of the Steam Deck. The cable isn’t detachable, so you can’t upgrade the adapter separately for better output.

Can I use any charger to charge my Steam Deck?

Technically anything that can connect via USB-C should deliver power, but all Steam Deck models consume around 15W or so while active, so you’ll need at least that to sustain a Deck, and more to gradually recharge it. Realistically, we wouldn’t use anything less than a 45W charger.

For maximum charging speeds you’ll want a 65W adapter. Anything rated beyond that is useable, but won’t make a difference — charging will be limited to what the Steam Deck can handle.

Another point to consider is the cable you’re using. For the best performance you’ll want a pure USB-C to USB-C cable, ideally one labeled as supporting “fast” or “quick” charging. At the least it should be marked for USB PD (Power Delivery).

Where can I get a replacement charger for my Steam Deck?

Just about any major electronics retailer should be able to help, as long as they stock adapters and cables meeting the specs we’ve mentioned.
