I regularly leave my phone in my car at work. I would like to keep it charged while I am away. But I cant find any outlets that have power when the engine is off. Does anyone know if there is bbn one on a 2019 XC90 T6 inscription.
It isn't available by design - it would risk draining your accu if you leave something plugged in for too long. There are fuses that you can tap if you want to do-it-yourself - I don't know exactly which one that I tapped (sun sensor I thought?), but just search my posts, I wrote it down in some post regarding a continuous powered dashcam!
Look for a battery that can charge while it is being charged. One connector charges the battery, the other to your phone. Assuming the battery stays connected to your vehicle all the time and the times the engine is on sufficiently fills the battery's charge, your phone will always be charged.
