Oop's..... the 10 is the better charger IMO.Good luck .. I returned the 10 and ordered the 5 ... we shall see. My app still says critical battery despite me asking PPF guys to put a charger on - then again - I see the status was updated 3 days ago - maybe it's dead already lol (or inside without reception) .. Hopefully get it back Wednesday ... the car that is ...So weird to have a brand new car and only driven it a day before vanishing for two weeks
