Mac Lock / Sleep Settings

I've recently switched over to a MacBook Pro after using Windows or Linux laptops my entire life. I love that when I close the lid the laptop turns off and uses very little power. When I open it, everything is up and running again like nothing ever happend. Crazy concept I know, but coming from years of windows machines, this is a luxury.

What I can't figure out though is how do I keep the machine running when I lock it without closing the lid? I run various VPNs and have programs for work that are painfully slow to compile / start. I can't leave the thing unattended while signed in obviously in an office, but I'd love to be able to lock it while compiling and walk around / grab a drink without having to reconnect to the VPN and having to resume the compilation of programs.

At the same time, I really love that when I close the lid it goes to sleep so I'd like to keep that feature as well. Is this possible? My fellow Mac users in an office, what do you do?

ISO: 12v 5amp power supply with USB port

Hello!

I'm looking for a power supply that can provide 12 volts up to 5 amps that also has a USB power port I could use to power a RPI.

I've hacked an old proprietary 3d printer apart and rewired it to use Klipper running on a Raspberry Pi 3B that talks to an Arduino with a Ramps 1.4 shield to control the motors and heat element. I don't have a heated bed so would only need up to 5 amps as that's the limit of the board. Right now I have everything working plugged into two power cables, one for the RPI and the other going into the Ramps board on the Arduino. I would love to get a a device that allows me to plug a 120V AC mains power outlet into it and provide me with 12 volts 5 amps and a USB power source I can plug the pi into. Does such a device exist in a small form factor? Would love for everything to be neatly contained inside the printer.
