Wiznaz for finding this deal.
Features:- Suitable for keeping vehicles/boat battery charged during the weeks unused. No need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back can observe the charging state. And it's waterproof, you can safely use it outdoors(After experimental test).
- The 10w monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging. Built-in blocking diode prevents reverse charging without extra maintenance at night. Works even on cloudy days. As frosted surface, the panel doesn't need film protection anymore.
- Equipped with SAE cable, just plug the cigarette lighter into the port or connect the battery terminal posts with the alligator clip, and the connection can be completed within 3 minutes! Suitable for car, truck, boat, lawn mower, motorcycles, trailer, dump trailer, tractor, RV, van, camper, ATV, utility vehicle Battery etc.

I mounted the solar panel into my sunroof under the glass, and routed the wires through the trim to the OBD port, which allows always on charging in my older car.
Follow up : I asked AI is it safe to use solar panels with an open circuit voltage of 20V. to charge my car battery?
AI Answer : Using a solar panel with an open circuit voltage of 20V to charge a 12V car battery can be safe, but it's recommended to use a solar charge controller to prevent overcharging. This controller helps manage the voltage and current, ensuring the battery is charged properly without damage.
Even though the price is great, I think I'm gonna have to pass after digging it to it a little bit.

These really should be marketed as charge maintainers rather than trickle chargers, and even that will be a stretch under anything but perfect conditions. There is no situation where you will put this on a dead battery and come back, even a week later, to be able to start the car.

I would not be able to recommend something like this to anyone, as if I recall correctly the OBD2 port draws power through the ecm so any wonky voltage or short might damaged the ecm for the engine and that might be a bit more expensive than a battery. Do you have the solar panel connected to something that is regulating output voltage/amps to the obd2 port?
- Charging through this device in a cigarette port.
- The drop of battery energy from turning the vehicle dash on so that the cigarette port powers up to charge through this device.
