This adaptor is only applicable for the following two Engel Fridge Freezer models MD14F and MHD13F-DM. All the rest of our larger portable models have this multi-voltage feature built-it.
Sometimes you may need your small Engel Fridge Freezer to run at home or in a hotel - and not in your car. For our small DC only model freezers we have a solution - the AC to DC adaptor. Plug one end of the adaptor cord into normal house current (110VAC). The other end is a female lighter/accessory socket (12VDC) - similar to what is in your car. Simply plug in your Engel DC cord into this socket.
