I put it on without the charging cable connected and it didn't stay on long at all. Only did this to take the car down from 100% charge as don't like leaving it there too long.). There must be 2 time settings with or without connection.
Thanks. I have mine set to come in about 15mins before we set-off in the mornings but now its getting colder I find it hasn't warmed up that much so wanted to give it more time. Can't find any mention of this in the manual.
Same again this evening. I have to do the dad taxi thing at midnight and would like to have it nice and warm before I depart, but not knowing how early I can remotely activate it makes it difficult. All this is whilst its plugged into the charger of course.
My experience is that if you have a timer it starts about 15 mins before, plugged in or on battery. If you send the request from the app it runs for 15 mins if unplugged and up to 2 hours if plugged in. I find starting it 30 mins before I want to leave works best, gets the fabric of the car warm as well as the air.
