That’s because the state is essentially responsible for house safety- there are many codes the buildings have to satisfy. Not everything is regulated like that. There are no many codes (if at all) associated with chargers, and charger safety is responsibility of a company making the charger. So at least I can see some logic here. But with low power devices like console the risk is very low to have someone electrocuted because incorrect low voltage (compared to what car is using to charge) card is installed. Maybe there is a risk of fire?
