Might be a bit of a silly question coming from an electrician

I have an Electrolux 3 way fridge (I think it's from a Vanagon, because it's 120v and has an American plug, two vertical flat pins) I'm not sure of the model number, it's in the garage at the moment (it's not the usual Westy fridge, has lots more controls... and an air pump!? - Possibly an RM182?)
My question... would it need a voltage drop-down converter to plug it into the mains (similar to this http://www.ebay.co.uk/itm/POWER-VOLTAGE ... 010wt_1255" onclick="window.open(this.href);return false;) or can it be plugged straight in to 240v using a travel adaptor?
Many electrical items with AC-DC power supplies (e.g. a laptop supply) operate from anything between 100-240v AC, so wouldn't need voltage converters, but I'm not sure about the fridge... I don't want to end up blowing it up!
