Converter charger difference

Thanks,I will use Randy when I get ready to purchase...

Call Randy www.bestconverter.com

I speculate it is something easy such as made for OEM vs consumer model. But same function.

Tried to cal them but their phone system really sucks ,it gets on a loop and will not accept any key entries..Not sure if the website accepted my question either ..Pretty poor communications for such a large company..

I would call Progressive Dynamics and just ask them. Most companies are helpful on the phone.
