Is there something that can plug into the Car that would charge the battery and also allow me to run 12v from it?



Example if i was to leave my Genesis at a show for a day. but still wanted to use allot of the power for lights and radio and stuff. But i cant start the car.



Is there a Battery Tender that is more than trickle charge?



Thanks!

 

Radio left on at a loud volume would require a solar panel big enough you wouldn't want to be seen with it on the car. Best bet is an Optima Yellow Top so it will be able to start to go home, or a spare (starting) battery for when it comes time to leave.
