For power supplies, I recommend one of the following:

For power distribution from the power supply (and on my battery box in the field) to all my 12V equipment in general I'm using a West Mountain Radio RIGrunner:

For power distribution on mount to dew heater, camera, focuser, rotator, etc I'm currently using a HiTecAstro Mount Hub Pro:
