I want to play VRChat with a Quest 2 wireless 100% of the time.

What accessories do I need to ensure I can stay in a private room all day without having to go to my PC in the living room? 

So far I got the comfort strap. How else do I charge my headset in the private room? Do I just need a charging cable and plug it into the outlet. How about for my hand trackers too? I wanna be able to just chill in that room uninterrupted without any privacy.
