EXTREMELY IMPORTANT TO NOTE - this adapter is for 20V Li-batteries. IT DOES NOT FIT the 18V tools & batteries. The B&D tools have quite many batteries types and fitting-connectors that are not compatible in between. Also - there are TWO TYPES OF 20V CONNECTORS, so one has to be VERY careful what to purchase!
The description & photos of this offer are not clear enough to guide the buyer and I porchased the wrong adapter (for the 1st time in my life).
