## Questions & Answers

**Q: does cigarette lighter port have to be active with the 12volts from battery? some cars, the cigarette lighter port shuts off when car is shut off.**
A: I have a Toyota RAV4 4WD, and a Hyundai Tucson 4WD. They each have 3 cigarette lighter type 12 volt outlets inside. None of them are live until the key is turned on.

**Q: I want to set up a campsite with my Honda Element., and I want to use the Schumacher so I can watch a TV or play the stereo. Will this work?**
A: when the sun is heating a lot (around noon) the shumacher pannel cell charges the batterie at 24 volts, if you let this charge  the car batterie you would be able to enjoy it, i use it to charge a 600 amps  car batterie that turn on 6 led light bulbs that consume 3 amp/h each (18 amp/h) and it work all night long, i think that this device will let you watch tv or the stereo separately but this will work as long as you have a clear day, y dont recommend you to plug directly to the tv or stereo because the solar pannels never send the same voltaje, all of them are designed to plug to an charge controller

**Q: Does the charger also come with a controller?The pictures displayed show the controller.But i also see it in the list of items frequently bought tog**
A: It comes with the adapter for 12V cigarette lighter and battery clamps, the controller is separate.

**Q: can it overcharge a deisel battery**
A: Batteries are usually lead/acid. Never heard of a deisel battery. Dosent sound vary efficient though...
