The present invention discloses a power adapter for connecting an electric appliance to an AC main power. An active current assist circuit is coupled to a buck regulator circuit, which includes a switcher circuit, an inductor circuit and a capacitor circuit. A magnitude of the displacement of a first of the inter-coded frames is determined based on the bits in the compressed bit-stream associated with that inter-coded frame. Embodiments of the blade include a blade converging in thickness from top to bottom and one having a curved upper forward edge region and one with a lower edge that has a distal straight section and a recessed section positioned proximal of said distal straight section. When in the folded position, the platform folds into the lower frame, which folds into the middle frame.
