Also electrically equipped with VanEssa mobilcamping.
In Volkswagen and Mercedes buses, we install a 230V feed-in and a 12V socket. You will also find very useful accessories for example CEE adapter cables, extension cables, etc.
Our recommendation for wild camping: To be independent of campsites, it is best to use a sufficiently large lithium power station (e.g. Ecoflow, Jackery | at least 500Wh) in combination with a foldable solar panel (e.g. Wattstunde SunFolder). This replaces the complex and expensive installation of a permanently installed on-board battery, can be used on the go and also has many practical features (including an integrated inverter, 12V, USB and USB-C ports).
