If they can make the touted 12k inverters and PowerJack does not keep them in limbo land forever,,,,,but PowerJack has sellers scams on eBay where they ship out a piece of paper and claim their order completed.. The Genery forum say Jack is doing the same thing like sending the picture of the GS 12kw transformer core . Those core are not for GS 12kw transformer . Sean say in youtube that Jack is producing the GS 12kw but no picture of the GS 12kw in production . Sid say the PCB is blank so the GS 12kw is NOT in production. Jack has a lot of experience from scraming buyer on ebay by sending pictures of inverter and now is sending pictures to Sean and Sean still believe the picture is real ?? . The picture of the 30000 kw 2 box inverter on ebay is not real and I message Jack and got a refund because 600 dollars by the ebay seller is too low for Jack .
