steam deck charger

[D.ckStacy]

When i connect the steam deck to any power supply other than the original one, the device does not charge. as soon as i connect the native charger, it charges.
I even bought an infinity lab instant charger 65w. I plug it in, no response.
Does anyone know what the cause is?

*I use fast charging cables (3 and 5 amp).

Most likely the cable if you have this charger.

InstantCharger 65W 2 USB (with a USB-C and a USB-A connection). If you have the older model that one isn't USB-PD3.0 I don't believe and won't work.

If you have that charger above then try the Anker USB-C to USB-C cable. I have this cable and know it works.

What reason is there for the stim deck to stop responding to third party chargers altogether. i don't get it.

Just to confirm, you are using a USB-C to USB-C cable with your charger (i.e. not USB-A to USB-C)?

There isn't, it is likely that the cable you're using is the issue as noted above or if the power supply you're using doesn't actually properly support the USB-C PD3 specification.

From the documentation of the power supply you mentioned it says it supports USB-C PD3 and supports the Voltage / Amprage combinations that should work with the Steam Deck.

I believe Steam Deck is self limited to 45W.

im use usb-a to usb-c

USB-A cannot support the amps and volts needed for charging the Steam Deck. It will only work with a USB-C to USB-C cable (and the right power source).

This is not a problem with limited amps and volts of USB-A connector. There are proprietary fast charging solution which does 12V and up to 3A on that. Problem is with the lack of CC (Configuration Channel) pins inside USB-A which are required for PD 3.0 to work (voltage and current negotiation).
