What video game are you playing this weekend? For me it's old Harry Potter and the Philosopher's Stone on PS1 emulator called ePSXe emulating PS1 on PC or Android.
That's how I do it, Bluetooth controller, wifi for sync and just a RPI with power and HDMI.
The bluetooth module in built-in on RPI 3, you can also use a cheap Bluetooth adapter for PC, it works too.
When the controller's battery dies I just play chill games like pokemon with my phone as a controller (RetroArch feature "Remote Gamepad") and keep going.
You can plug you PC or laptop to the TV in the meantime. 😎
