Automotive power sockets and vaping: the correct info

[Oomee]

An electrical outlet doesn’t push current to the load. The load (the dongle battery charger that the battery screws into) pulls only as much current from the circuit as it needs.

The Volts , electro motive force , push the current through the load .
Remember the old plumbing analogy , you need the pressure to get things moving , no matter how low resistance a path .

Okay, so pardon me if this has been addressed but I read through the posts and got lost pretty darn quickly! ha!
My Nitecore i2 came with a car charger that just plugs into a separate 12v plug on the charger, instead of the 110-240v for wall outlets. My truck just has a cigarette lighter that I know will charge the thing, but before I do so I want to check to make sure its not putting out more that 12v? Correct? There is no power to the cigarette lighter when the truck is off so it won't charge unattended, just for the long trips up north.
I haven't used the car charger because of this. Don't want any battery mishaps going down the freeway at 80!

It is going to put out more than 12v, probably a little over 14v, but that's ok.

There is a remote possibility that something could go wrong with charging, most likely due to a damaged cell, so if you're looking for an uneventful drive, that's not the way to do it.

Ideally, you'd have a temperature monitor with an alarm, to let you know something is wrong, but that's outside what typical chargers are designed to do.

If you're going to do this, IMO, the best thing you can do, is put the charger in a charging bag:
Li-Po GUARD 25x33cm Safety Battery Charging/Storing Bag
(a fireproof enclosure. Any good metal box would do)

Then all you have to worry about, is a puff of smoke coming from the inside of your vehicle.

There's only a very remote chance that something's going to go wrong, but if you're concerned with a possible distraction, IMO, that's as good, and reasonable, an option as you're going to have.

You’re right. To make my point, I used common terminology that’s easy to understand. To follow your plumbing analogy, electrical current is like the volume of water flowing through a pipe. The resistance of the components in a charger will limit the amount of current that can flow through them.

If a charger is operating properly, it only allows(pulls) a certain amount of current flow.
