Asian Power Devices WA-18G12U Power Adapter for Select WD External Hard Drives

This Asian Power Devices WA-18G12U AC Adapter, is the same model that Western Digital ships with their My Book Essential and Elements External Hard Drives. Why settle for a generic knockoff with questionable quality, when you can have the original for nearly the same price? This adapter was bought in bulk from Western Digital and will not come with any retail packaging, the sale only includes the adapter itself.
