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. Simply plug in your makita battery and the old dewalt tools are ready to use.

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 has the proper circuit inside so it won't drain your batteries even if you leave it on and forget about it.

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!
