Continuous Stepless Linear Voltage Regulation. 

The contactless inductive transformer makes the linear voltage regulation. No tap from the transformer, so there is no coupling noise, and voltage drop is very low.

No Arc Discharge(Sparkle). 

No contact point inside the transformer,  there is no arc discharge.

High Efficiency. 

The winding of transformer is made of high purity oxygen-free copper wire, the copper loss is low, and the temperature rise is slow.
