In terms of electricity, I have two 12V batteries in the van that are connected to the main car battery. So, whenever I drive, the two batteries get charged and they don’t drain the main car battery when I’m not driving. With these batteries, I’m able to have lights inside my van, I can cook with a hot plate, boil water with my small kettle, as well as charge my phone and laptop. So basically this is all the electricity I really need! Of course, I can’t make elaborate meals, and cooking takes a little longer since I can’t use the hotplate and boil water at the same time. But, overall, the set-up works well! Some people even have solar panels on the roof of their van which I think is a fantastic idea and something I would eventually like to add.
