CUZEC 2-Way Splitter, SAE Connector,1 to 2 SAE Connector Power Charger Adapter

It you're into solar or other 12V automotive battery items, the SAE connector has become extremely popular and is easy to use though it is also easy to reverse polarity with. These "cigarette" style adapters give you yet another way to connect to the power. These are well made but of medium use. They are not designed for heavy amperage draw but are great for 10 - 15 amp requirements.
