no worries I just wasnt sure if you were talking about something else like the mk 1.
Most of the time when an American company has the Chinese design market a specific version like the 120v version of this pump, or the intertap beer taps for example, they sign an agreement not to sell direct to those countries for a specified period of time otherwise it would destroy the business since there seems to be up to 100% markup these days vs buying from the manufacturer with their markup.
Traditionally keg king doesnt design things, they copy others designs or rebrand stuff. based on thier operations in the AU they get away with it pretty well.
These days more often than not, in the US we have our own scams such as UL listing to try to keep the big corporate fakes in business selling this stuff under their names with this "certification" for 2-3 times the price vs making our own products.
