A for a beefier power supply converter, this is what I have my eye on and
might get soon.

This is more than enough amps to power the node, and in my instance, keep
my hotspot powered and charged at the same time. In my opinion, it's better
to have a supply that's bigger than your draw, so it isn't working at full
steam all the time. I think it even has a spot to wire a 12vdc fan. You
could probably mount the fan on the top, and pull hot air away. Self
tapping screws that catch the fins and secure the mini fan. At 5A, it
probably won't get very hot anyways, but in a vehicle, it's best to have
more cooling if it's continuous duty.

These adapters work very well too. I have several in service.
