It is of much higher quality, has intelligent features (app-controlled) and is much faster. There is also a version for 220V and 12V. I'm looking forward to the first tests!
Unfortunately I can't say anything about this, especially as I have only used the lunchbox with the cable supplied so far (for the normal house plug, not for the 12V plug in the car as is often the case with coolers)...I think the answer from "Büttner" helps more...
Not directly. Only via a 12v to 220v converter. Since the unit only has 70 watts of power, an inexpensive converter up to 100 watts is sufficient. However, it may be worthwhile to purchase a good device (sine wave) that is also suitable for more sensitive devices such as laptop computers.
