Nice video; informative. "Fudge" the naysayers that ONLY nail you for trying to help people out! I don’t know if it's the times but it seems like EVERYBODY is out there looking to slam people for just trying to help.
Nice video. Battery tender now makes one of these obd2 charge connectors. Whether the end connection is compatible with the harbour freight connection I'm not sure. Anyway thanks for the great video.
Everything I've seen/read about a low output panel like this says no. I leave it connected for weeks at a time to my Tundra and no problems. I also leave one attached to my dual battery travel trailer for weeks at a time with no ill effects. My trailer battery is consistently reaching 13.2-13.4V of surface charge when I go check on it. This is just to keep a battery that sits for a while from dropping to a damaging charge state. It won't act as a charger for cycling unless you want to cycle every month or so and wait a LOOOOONG time to use the battery again.
There is no point trying to save power by disconnecting the small blue neon, it does not save anything that is measurable, just imagine having the panel charging for days then as you open the car door the interior light comes on, or even the car alarm warning neon flashing away, so disconnecting that little blue neon is hardly worth the time and effort.
The entire panel in direct sunlight puts out 1.5 watts (claimed). That's not much to begin with, so any little bit helps! Every time I visit my RV in storage the battery voltage reads about 13.4+ of surface charge. So it is actually working. Let me know if you try this. As another viewer posted, there are now some connectors available with other solar maintainers to do this type of connection.
@@fungames24 It tells me that if a car with a power drain of 20mA can sometimes kill a battery in a few weeks, depending on battery condition, that an equal amount of power subtracted from the production of an already under powered solar trickle charger will equal trying to keep TWO cars maintained with one charger.

You've been paying attention!

Thanks for the info!
Great video!
Will this overcharge a 12v car battery if left unattended for a couple of days/weeks? Do we need a charge controller?

5mm LED consumption 20mA. Nissan 1.2 liter consumption 30mA. BMW 3 liter consumption 20mA with intermittent 60mA spike. What does the math tell you?
