the resistance of the bed is fixed and its this that determines how much current it will pull.
standard pcd heated bed are 1.1 ohm so at 5v it will draw 4.545amps.
Thats 22.72watts vs the 130 on 12v
so whats that in temperature? that’s beyond my math skills..
but my guess would be it would take several hours to get to 50c
