For adapters that are rated for a single input voltage, the efficiency measurements are

made at the input voltage (115 VAC or 230 VAC) specified on the nameplate. For

universal input adapters, the measurements are made at both nominal input voltages

(115 VAC and 230 VAC).

To comply with the standard, the average of the measured efficiencies must be greater

than or equal to the efficiency specified by the CEC/Energy Star standard.

More states within the USA and other countries are adopting this standard, for the latest
