EN48 - Your right, I hadn't considered the fact that at 12V you need a much greater amperage for the same wattage. I will see what amperage the aux power circuit breaker is rated at and go from there, but either way for the small devices i would like to charge/operate on longer trips 10A would no doubt be sufficient. With regards to installation, i'm in the uk, and not considering this as a permanent attachment, rather a portable plug in accessory in itself... I will test to see how hot the unit gets and decided what precautions will be necessary to ensure that it doesn't cause damage wherever I choose to locate it. I'm sure the documentation associated with the unit will suggest certain precautions. Thanks
