What cooking utensils you bring for a self-driving picnic depends on what you are going to do. If it is a barbecue, be sure to bring barbecue charcoal and iron skewers to facilitate the barbecue. If it's home cooking, you're in trouble. Even if your car has 220 power supply, you can't use the induction cooker. Because the power is too high, it is too difficult for you to connect an external power supply. You can't bring a gas tank in the car, so it's meaningless to bring a home-cooked cooker. It is easier to barbecue in the wild, because charcoal is easier to carry and burn.
