I'm often in the position of wanting to leave my cell phone in the car, and since they are smart enough to relay off when filled, and lithium ions actually prefer to be shallow charged often, it will not hurt anything. There are *other* reasons for wanting always-on too, not worth getting into.
However, I've discovered that contrary to what the salesman told me, it shuts off when the car is shut off.
Is there a configuration under the hood or elsewhere to easily enable this, or am I going to need to wire something? If these power sockets are on their own circuit all by themselves, I can do this easily (approximately 1 minute) at the fusebox with my own inline fuse, and a line from one of the always-on circuits to the prior fuse position. Done this before.
Anyone know if there is a turnkey solution to this somewhere?
THANKS
