buttons?

[Donk_UK]

Hi all got a new surf well new to me anyway and I am a little confused by some of the buttons the ECT PWR one mainly. A friend of a friend says that when you use this it uses less juice. I do notice a big increase in performance with it on but am not sure whether its better for consumption. Apart from that all is good
