OK, challenge accepted, lol.
I'd love to see you use 2.5kW of power from a real life V2L situation, I'd also love to see the cable you run from the car into your home and then to the devices you suggest above (one would assume that you moved the fridge and kettle into the same room as the TV, router etc.?) - this is not a realistic use for V2L, perhaps you are confusing it with V2H?
V2L is designed for 'out and about' uses such as charging electric bikes, scoots, perhaps for devices such as a coffee machine and lights when camping etc., not for powering your house during a powercut.
Lastly, solar generators do not use petrol, they use the sun (or leccy) to charge, the 'generator' part if the product type name is a bit of a misnomer
