Probably one of the least flashy accessories, but I bought a 10 foot long USB-C cable that lets me sit anywhere on the sofa and play without battery anxiety.

I use a jsaux modcase instead of the included carrying case, it provides enough protection and fits better into my backpack for work. I’ve got a 3rd party ivoler dock I use for my TV, and 4 stadia controllers for docked play. Finally I have a walmart onn brand BT tablet keyboard and a trackball mouse that I can use while it’s docked.

Everything from this 2023 reddit post

• 65w usb charger
• usb-c cable
• slim usb-c hub from anker
• piece of string, to turn the box into a cradle

i also carry in my purse:

• 3d-printed microsd organizer
• small bag of usb adapters, for charging friends’ phones or connecting a flash drive, etc
• dualshock 4 controller, modded with back buttons, a usb-c port, and a phone holder
• slim mouse and folding keyboard

I used to carry a battery pack but its heavy and rarely used, so now I just carry a second usb-c cable and a c-to-c extender and hopefully i’ll be able to reach an outlet.

A dock and kb+m when I know I’ll have space, a DeckMate used to attach a battery pack when I don’t

I have a silicone case on it, but only because my kids started using it. I also have a dock hooked up to the TV, but I never use it.

I mostly play handheld, and I got a gaming pillow from Mechanism. It sits on my lap and holds the deck at the right height and angle. My hands used to fall asleep from squeezing the deck to hold it up, and this has solved it. I would play docked more often if I had a controller with rear buttons.
