Shadow JM35: MT G2 one one cell!!

It is a 2A boost driver ( meaning MT-G2 will get 2A output at 6V from 3.6-4.2V input source). So of course it is is not a 6A boost output as the title implies, I guess it was specified/targeted towards people who are are not familiar with step up and step down drivers, but with linear drivers. But well, I am talking only based on specs, I mean what makes the specs accurate? only testing the output current for various LED voltages 6V, 9V, 12V.
