Im looking for some guidance. I will be tent camping and the only electricity is for a 3 prong RV hookup. I found an adapter that goes 30 amp to 15 amp and has normal 12 volt, like in in your wall style female end. I dont want to fry my on board charger or anything else for that matter trying this so hoping someone has some experience with this. Googled this pretty hard but cant find a clear answer...

Or if someone else has another solution for charging I am all ears.

Thank you!

sure thats not 120v ? if so that should work . the 30amp is still 120v.

RV hookups are 120 volt.

Sounds like you are confusing amps with voltage. It is the same voltage at your house that you plug the charger into. your wall has 120v, your battery is 12v but your charger runs off of 120v. All that you need is the adaptor so the plug fits and it will be fine.

Thanks for the replys, information overload from the internet has confused me.

But sounds like I am in good shape for getting power! Thanks again for the help!
