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 a short battery life even when it’s fully topped off.

Valve’s own USB-C charger supplies 45W of power. 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 connects via USB-C should deliver power, but the Steam Deck consumes around 15W or so while active, so you’ll need at least that to sustain a Steam Deck and more to gradually recharge it. Realistically, we wouldn’t use anything less than a 45W adapter.

For maximum charging speeds you’ll want a 65W adapter. Anything with power 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.
