This is the email I received back from them, I still don't understand if it is functioning right..

Hi Eric,

The LCD showed your plug load is 0.7A in 1.2 volt range. If you turn to the higher position (clockwise), the voltage will be rise and the load could be up to 0.9A or higher. It depend on what kind plug you take - Hot or cold type & brand. Don't worry, it is in normal running
Thank you.

Danny

If anyone can shed some light on this, I would appreciate it...
