Is there any thermo electric coolbox (or cool/heat combo box) available in the market, that fits in the center console of RDX?

 

This is the only thing I've seen out there. It's listed under the Interior section of this link.

Does the cooler bag can able keep milk or drink cold for 6 to 8 hrs, if I fill the bag with some ice and climate control is set to 75F?

 

Yes for sure. I froze the whole bag in the freezer, added some ice and an icepack and it kept drinks cold, with ice, for almost 10 hours. This was also outside for a few hours with temp around 85. Good product.

 

The cooler bag was one thing we asked the dealer to throw in for free when we bought the car. It has come in handy since we visit our family on a regular basis that lives 7 hours away. We put ice in it and it keeps our drinks cold the entire way. We usually have some unmelted ice leftover after the 7 hours when we unpack at our destination.
