Ideal if you have a parasitic draw on a vehicle that you may not drive very often.
It's ok if you don't understand 12v systems and what exactly a trickle charger is.

It's basically a trickle charger. Sends 1amp to the battery to maintain the car battery at 12.5v. Will also keep power to the interior electronics when you change out a car battery to keep from dropping memory/presets.

Lithium ion is a lot more energy dense that lead acid. A 50 amp hour battery has about 600 watt hours (50 * 12). A DeWalt 4 amp hour battery has about 72 watt hours (~18*4, 20 volts is the max not nominal). So that means an over 10% increase in energy. It's enough that if you leave your car in the airport for 3 weeks it is more likely to start up again.
Yeah, the "airport" suggestion sounds good.
I was trying to think of the use case, why would I want this instead of a trickle charger. And the answer would be when I didn't have any place to plug in a trickle charger.
