I have the more expensive one...I am not a battery expert
But if you google chargers, you will find one like the expensive one Porsche sells for about half the price but doesn't come with the cigarette lighter adapter. I quickly scanned the pages, but here are the highlights.
A few of the main reasons are...paraphrasing
Won't overcharge the battery, no matter what construction it is, wet, gel, etc
It's safe to use indoors, because it won't let the battery outgas, and won't cause damage to interiors.
Has a voltage and amp regulator to "soften out" the voltage "ripples" so that vehicle electronics don't get fried or weakened
Keeps the battery from sulfating
etc.
