Bought to power baby swing - doesn't last
While they function a D-size batteries, we placed them in my infants battery powered swing, and the batteries barely last an afternoon. Generic D-size batteries from the grocery store usually last a week. While the charging is better for the environment, it sure is a pain to change these 2x a day. In other devices, the D adapters appear to be lasting a lot longer, so it may just be an isolated instance in the swing.
