  • Battery Holders and DC-to-AC Wall Transformers to power your inverters.
  • If you didn't purchase a "portable inverter" you need an external power source to power your inverter.
  • 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.
