Siphon rule

Be sure to follow the rule before you head out.
Rule: You must post before you leave.
I changed off a 12v 20amp outlet for over a year at my house till the charger was installed. It would take 12 hours to charge from empty to full but never had that happen except going on trips, then I would use the DC charging stations.
You have a 12V outlet? Why not use 120V or 220V that everyone has?
