Let's say I want to have a spare car battery in my car.....
So if I set a good car battery in the passenger footwell, so I have a way to self-jump my car if I end up in the middle of nowhere with a dead battery; is it feasible to use a set of alligator clips on the battery, and a male plug into the cigarette/accessory socket, with maybe a trickle charger in the middle? Just to keep the spare battery topped off.
I looked around Amazon a bit, not seeing it, not sure of the terminology I need.
Plenty of trickle chargers for plugging into the house 110 line. I suppose I could stick a 12v to 110 converter in the socket, then plug a trickle charger into that, and run that to the spare battery alligator clips, but I'm looking for something more elegant, that doesn't have to convert from 12v to 110 then back to 12v.
Anyone with knowledge or experience they can share? I want my running battery to share with the spare, but I don't want them to both go flat at the same time. Just a 1-way power trickle to keep the spare at 100%.Attorney Phil Kline, AKA gunlawyer001@gmail.com

I mean yes, but so many companies now make and sell really small Li-Ion jump packs, that really do work, that I'm curious why you'd want to go a different route?

Every one of those plastic battery packs that recharge from the wall, that I've ever seen, had died.
This ad ("Amazon's "pick") brags that it can hold a charge up to 12 months, but it will probably discharge from the time it leaves the factory to when you get it due to "long shipping times", and you should remember to charge it again ever 3 months. I have enough hobbies, I'm hoping for a plug & play deal; that I don't have to mark my calendar over.

here's a jump box that can be trickle charged while in the car, every time you drive, it gets charged:

hope that's what you were looking for, lot less hassle than having a whole battery on your floor.
