Hello D.h. Unfortunately, I can't tell you exactly either! Galaxus or the manufacturer would have to tell you. What I have noticed myself on Galaxus is that the different colours seem to have different prices. Colours that run better and are produced in higher numbers seem to be offered at a lower price. In addition, the cheaper models have an additional USB port (as an alternative to battery operation) for the fan. I cannot explain why this additional functionality is cheaper. Perhaps they are different product generations. In terms of weight (both 3.70 kg), there are no other differences, so they are probably identical. The grill works very well and is also recommendable for 2-3 people for the lower price. So why pay more ;-)
