  • Match the inverter voltage - 3v, 9v or 12v - and choose battery holder or wall transformer which ever suits your application best.
  • Battery for portability or Wall Transformer to plug into an electrical outlet.
  • Purchase mating FEMALE plug connector (1.3mm or 2.1mm) and attach to your inverter for connectivity if you are purchasing a wall transformer.
