  • The EF20iST incorporates a completely new controller with advanced programming resulting in improved output characteristics between 1600w-2000w operation ranges. The addition of the new programming allows the EF20iST the ability to power a much wider range of applications than previous generation EF2000iS.
  • If you need extra power the EF20iST has you covered—a convenient parallel function lets you connect two generators to deliver up to 30 amps.
