Always carry a fire extinguisher under the passenger seat
Crap chargers, crap batteries, crap phones and other crap infotainment electronics. It is a small wonder that there are so few fires. I barely saved one of my cars after the stereo combusted and set the central console on fire. If it was just 20 seconds later the car would have been a write off. In this case, a new console off E-Bay, new switches, one hour of crimping and two days of cleaning resurrected it (for now).
While doing it I noticed a few things - the fire retardants in the modern car ABS do not fire retard. The f*cking thing still burns. The fuses are not particularly effective either. They will not blow even if half of the console is on fire and both the stereo and the accessories are short provided that it is "fried electronics short", not a direct one.
