Cell Phone Charging While Camping

[schnisz]

Hi, I"m taking my 450h camping for the first time and want to be able to charge my iphone without draining the battery by keeping the motor on I assume? I called my Lexus dealer and the guy said "yeah, I think its something to do with eco setting" and that was all I got. I know how to change the car eco on and off, but not sure if thats what I need. He also said the battery drains pretty fast if the engine is not on. Thanks

I bought a cigarette lighter receptical and went to a car stereo shop. They installed it to a constant on connection and I can charge my phone even when the vehicle is off. It works great and I've never had a problem with the battery. I paid less than $75.00 total and it was worth it.

thanks. I really don't want to spend anything to accomplish this. I guess question should have been how to keep the engine on?
