On the same note, and NOT pertaining to the generator, I was told a while back by a B&D/DeWalt tech that the 'HD' within the model # was not 'heavy duty'; it signified a model made exclusively for HD.
Comments continued that the 'quality; of the internal parts were not the same as the model without the 'HD'. In lieu of rebuilding that cordless drill, I opted for a 'factory refurb'!
