The PLUS220 power supply is similar to the current model in that it is a 50Watt, auto-ranging (90- 260VAC, 50-60Hz input) supply with a 20VDC output. However, the new cord is improved by the utilization of an earth-grounded C5 type plug, which includes three prongs rather than two.
The PLUS220 power supply and its cord are matched only to each other, and are not compatible with the current power supply/cord using a C7 type plug. The PLUS220 supply/cord is the same length as the current unit (about 6 feet or 1.83 m), and the power supply (brick) is slightly smaller than the current unit.
