Steam Deck charger wattage

Valve lists a 45W USB Type-C PD3.0 power supply for Steam Deck — shop that USB-C PD class (or a verified 65W GaN travel brick), not a random phone cube.

Manufacturer input is one line in Valve’s Steam Deck Tech Specs & Facts press sheet: Power → Input → 45W USB Type-C PD3.0 power supply (accessed 8 Sep 2026). The same sheet lists a 40Whr battery. Full method for reading any brick: how to pick.

Official power input

From Valve’s LCD Steam Deck tech specs PDF. Match the USB-C PD wattage class before you replace a lost or broken adapter.

• Device Steam Deck (Valve tech specs PDF) Listed power input 45W USB Type-C PD3.0 power supply Battery (same sheet) 40Whr; gameplay life estimate 2–8 hours (settings-dependent) Shopping class 45W USB-C PD / GaN to match Valve’s published input
• Port USB-C (also DisplayPort 1.4 Alt Mode / USB 3.2 Gen 2 on the same sheet) What that means Use a USB-C PD charger and a USB-C to USB-C cable rated for the watts — not USB-A-only phone leads Optional headroom 65W multi-port GaN when you also charge a phone from the same brick (check the port’s simultaneous-output table)

This page cites Valve’s LCD Steam Deck press tech specs for the 45W PD3.0 line. We do not invent a separate OLED wattage table here — shop the same USB-C PD class on 45W unless Valve publishes a different input for your exact model.
