Question about Steam Deck, and Legion Go

[sys64738]

Question about Steam Deck, and Legion GO:
SD has 45 W, LeGo has 64 W charger.
Can I use the chargers vica-versa to charge this two Handhelds?
Another question:
What kind of jack plug Headphones can I use for this two handheld?
3, or 4 Pol (with mic) jack?

Both devices use PD (Power Delivery) chargers so they are safely interchangeable in general, but I don't know if the Steam Deck charger is powerful enough the charge the Legion Go while actively gaming. It won't hurt to try though. This also means you can buy any 3rd party PD charger 65W or higher and get the fastest charging on both devices from it.

Both devices can use TRRS (4 pole) wired headphones and will use the headphones mic when connected. I dunno about the Legion go, but I recall the Steam Deck having issues with TRS headphones (3 pole) causing the built-in mic to still be disabled even though TRS headphones don't have a mic of their own. Not sure if this was resolved via an update or is a hardware issue - nor do I know if the Legion Go had/has this issue. That said - there is no risk of damage to either device with either jack type.
