Sorry – can’t help – I’m with OVO and my charger is ohme.
But I am able to pre condition my car plugged in or not – very useful for defrosting and cooling – I used to struggle to scrape the car in frost – having to support myself on the car with one hand and scrape with the other – now I just go tell it to defrost from my iPhone app and 15mins later it’s done.
So I would check out the extras between them!
