Porter Cable 20V to DeWalt 18V Battery Adapter

Use your Porter Cable 20V batteries on DeWalt 18V Ni-Cd cordless tools, without buying into a second battery platform. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. It removes the need to keep separate batteries for different platforms, which saves money and simplifies the workflow.

• Injection-moulded ABS, not 3D printed — no layer lines to split under load.
• Solid copper terminals, so less of the current is lost as heat.
• 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
• A USB port on the adapter, so the same battery charges a phone on site.
• Covered by a 12-month warranty from the day it arrives.

Porter Cable 20V and DeWalt 18V Ni-Cd compatibility

It works in one direction only: Porter Cable batteries powering DeWalt tools. For the opposite pairing, see adapters that run on DeWalt 18V Ni-Cd batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Porter Cable 20V platform and that your tool takes DeWalt 18V Ni-Cd batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Porter Cable or DeWalt batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Porter Cable 20V battery.
