Guy mentioned 6 TH and even 6.5 TH a number of times here without qualifying the statement by saying 'but not on 110 volts'
Then let yours mine on an AAA battery and ask for compensation.
Thats a feckless remark. The specs don't claim it will run on an AAA battery. They do claim it will run on an input voltage of 90-264 volts AC and they do not qualify the performance based on input voltage.
In fact, there is no good reason that the SP30 performance should depend on input voltage, provided it is within spec.
