Does anyone know which outlets and USBs are always live (as in with power), even when the car and engine is off? I’d like to charge my phone overnight. Have the 350h if that matters. Thanks for the help!

 

You could tell by plugging your phone in, which will indicate charging. But I'm not sure I'd use anything that draws from the battery plugged in with the car not running, especially on a hybrid.

 

I don't think any of the USBs are live. Even if you left it in accessory mode, I think it will auto power off after a while, and then you may need to charge your car afterwards as well. you better off have the car in ready mode (meaning on) and then charge it up before you power off the car.
