Having a car adapter is great as this has come in handy for a road trip already. It doesnt hold much but as shown in my pics it can hold up to 6 soda cans. Weve only used it as a coolerrefrigerator so I cant really speak on this as far as a warmer but it definitely does get warm. 

The fridge shelf is removable and so is the door shelf. This comes with a pen, car adapter and plug. Its pretty neat though and now both of my kids want one for their rooms. Its smaller than I thought it would be but serves its purpose well.
