Note: Progressive Dynamics Inc. converter chargers are being advertised on Amazon, Yahoo and Face Book under the name of Progressive International. This name is to imply that Progressive Dynamics is somehow involved with Progressive International and we are not. The real Progressive International sells RV kitchen products and not converter chargers. Progressive Dynamics and the real Progressive International only sell through authorized RV distribution companies and RV dealers.
