Got an old Dewalt 18v post style tool from the ni cad battery system?

This adaptor will give it a new life, plus the new slide on battery which is based on Lithium ion cell is MORE powerful as it discharges higher current. Genuine product from dewalt.

Also please be wary, some unbranded products that have a usb port may drain your batteries slowly untill empty and eventually wreck it. This one is genuine dewalt so would be safe and good to go.

But be sure to check that your tool is the 18v Ni-cad system not the 14.4 or 12v, and this adaptor can't be used for charging, only between tool and battery, not battery and charger.

Cheers and enjoy!
