Well, I sent it back and they sent me exact same model (from China again), but without
the LCD watt & volt meter. They installed a blank steel plate in the LCD hole..
Tonight, I see another seller has the large version 1200 watt Power Jack GTI..
They even have a ($250) high input voltage model (50v to 100v).
