Handheld gaming device charging typically uses USB-C PD, commonly 45-65W. Devices like the steam deck and modern handhelds use standard usb-c pd, meaning most laptop chargers work, though undersized chargers may not keep up during active gameplay.
What to know before buying a replacement
Check the original charger’s exact voltage and connector before substituting a generic one — handheld gaming device charging systems vary more than phone or laptop charging, where standards have converged.
