Out of curiosity I just searched “Peugeot e 3008 v2l” on Google and the second search result was
If you scroll down to the charging section it says “The new E-3008 also features a V2L (Vehicle to Load) function, giving customers the option of powering an electrical device via the car’s high-voltage battery. The system can supply up to 3kW of power.”
Don’t know if this is helpful in challenging Peugeot.
