Car Fridges , help with some stupid questions please

[Winnie]

So what the deal, it seems like car fridges sre no good at cooling anything thats not cold already ?, sounds like you have to make sure "everything" that goes in the fridge, comes from a fridge ?

Lucky they have a drain plug, cos it sounds like ill be putting ICE in mine now and then if thats the case ?

Bahaha not at all mate. People just do it to save power. If you put warm things in the fridge has to work a little harder to cool it down. No harm to the fridge but uses a little more power.
