at least in the USA you have two choices, the cooler box and the refrigerator. Cooler box is a $355 option and the Refrigerator is $715. the cooler will keep things cool the fridge will cool things due to it lower operating temp. It will drop down to around 25 degrees for a short while while on high to accelerate the cooling. It is a nice feature I have the fridge and i do use it all the time, But if you don't really care about having cold drinks in your travels and rather have storage than leave it off.
