I carry a backpack with the steam deck in its regular case. In my backpack I carry a 70% keyboard, a mouse, and a dock/hub thing to connect to a monitor/tv. I keep a Lenovo charger because the cord is very long. I guess I also keep an Xbox one controller. Everything is just tossed into the bag.

I did order a case on deep discount that could function to store more things should I not bring a backpack, but as if yet that hasn’t happened.
