Battery Tender 12v SAE Cigarette Lighter Adapter BTLighterA081-0069-5

Pros: I took a chance hoping that the BTLighter Adapter, even though it was not from the same company (Battery Minder), would still work with the Battery Minder. And it did. The connection worked perfectly and plugs right into my constant battery cigarette lighter adapter. I needed this sense my set up would be all out doors, in all weather. So, I wanted to charge my battery in the safe, cozy and dry confines of the interior of my van. The Batter Minder (with this Battery Tender adapter) sit on the floor of my van plugged directly into the constant battery (not connected to the key) cigarette lighter. It charges my battery every weekend with no problems.

Cons: None, other than I had to call Battery Stuff to make double sure that the Battery Tender cigarette lighter adapter would be compatible with the connectors on the Battery Minder. Other than that, everything works perfectly.
