Hello bonito The cable is approx. 275cm long including the plug.

I once had the box in the car for about 6 hours in the blazing sun. Of course, the box can't keep the temperature constantly low, but I was still pleasantly surprised at how well the coolness was maintained. All in all, I'm very satisfied and can get by without a compressor cooler. However, if you need a constantly low temperature, you probably can't do without a compressor box.

The connection cable with the plug for the 12V socket in the car (cigarette lighter) is included in the package.

I still have a box like this in my office, but honestly, you'd better buy a compressor fridge. you won't get anything cold with it.

According to the manufacturer's website, the device can be operated with 12 and 24V DC in addition to 230V AC: https://www.dometic.com/de-at/outdoor/essen-und-trinken/kuhlboxen/elektrische-kuhlboxen/dometic-tropicool-tcx-21-31799

Yes, everything is "saved". If the box is not switched off manually, all settings are retained. Also works when changing from shore power to 12 V or vice versa.

As far as I know, TC is an older model. In any case, it looks different in photos. Unfortunately, I don't know whether it differs in terms of technical data. Sorry.
