smart: I want to buy either a mini fridge or an electric cooler. What's the difference? What's best? It's for the house, a temporary solution. I want to be able to keep milk and eggs in it.What's better: an electric cooler or a mini fridge?NEITHER the electric coolers are useless, they use thermoelectric cooling technology....which is exactly how a computer's processor is cooled. it basically lowers the temp inside the cooler box like 10 degrees lower than ambient temperature. get a mini fridge that has a compressor unit that drives refrigeration fluid and make the temp in the box ice cold.What's better: an electric cooler or a mini fridge?if you want to keep produce in it i'd say the mini fridgeWhat's better: an electric cooler or a mini fridge?Any compressor type refrigeration unit will perform far better than one of the electronic models.
