Keep in mind that if you got the fusion ultimate add on kit, it comes with the car charger, but the amperage on it is less than needed for a pass
through. I don't know if the trifecta's work like a PT (put the power straight from the charger to the carto), or like a battery that is charged while using. If the former, might want to get a higher amperage car charger, probably find one cheap on ebay/amazon if the bloog max is out. If it's the latter, you should be fine with it.
