Ryobi Battery to DC-DC Converter with 12V Acc Port

Mashup of the 2 source files allowing a Ryobi battery to connect to a 12V automotive accessory port. Used this to power my laptop via car adapter.

Designed (poorly) in Tinkercad. It was a good learning experience.

Some parts:

  • DC-DC converter 24V -> 12V (Amazon)
  • Generic 12V accessory port
  • Battery terminals (Digikey part: 36-204-ND)
  • Various wires and screws and a fuse
