This is a great idea. I wonder if it really avoids overcharging like they claim.

Isn't 10W slow, even for a trickle-charger?

I have this and have not had an issue with overcharge, there's a circuit of some sort on the back side. I have it on the dash of a seldom used car to cover vampiric drain from the ECU, remote start, alarm and dash cam. I used to use a Genius 1 tender but ext cord running outside bothered me.

Interesting. So, it can charge 12v via the cigarette lighter port?

Bought one of these a few months ago for my tractor that sits for weeks at a time. The battery is old and I would usually need to jump it but this has been keeping it at 12.8v and it fires right up. So far so good.

I've seen cars isolate ports on power down.

That is why alligator clips for direct battery connection are included.

I initially tried 10W but had to upgrade to 20W considering the energy loss of putting it behind a tinted window and also not having the ideal orientation.

I wonder how this compares performance wise to the solar Battery Tender
