ISO: 12v 5amp power supply with USB port (lemmy.ml)

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.

Using a USB car charger to get the Pi's 5V from the 12V is likely going to be easier. I don't think you're going to find what you're looking for otherwise.
