Comments about Wagan Wagan 9903 5Amp AC to DC Adapter for Thermo Fridge, Cooler, Warmers, Air Compressors:
I use this device indoors to power my Garmin GPS & MSN connection. The MSN connection must be powered with a 12v adapter. Consequently, I use this device when I am preplanning a trip or doing research at home (e.g. lowest gas proces in area, weather, etc)
