The 12 volt outlet on the Hopkins Multi-Tow Trailer Connector Adapter, # HM47675, can be used to maintain a trailer battery but it will not be able to charge it. The gauge wire used to provide power to the 7-Way is too small to effectively charge a battery, but it will provide enough power to keep it from draining.
