What is the power supply capacity of the Blue Smart IP65 12/15? Can it be used as a power supply for a 12V Dometic CF18 portable fridge / freezer? Dometic's Mobitronic MPS-50 mains rectifier has a 6 amp output @ 24V. Since the fridge is rated 7A, I suppose the additional MPS-50 capacity (150 watts) is needed for compressor surge.
