DeWalt 20V to Porter Cable 20V Battery Adapter

This adapter lets you power Porter Cable 20V cordless tools with the DeWalt 20V MAX batteries you already own. Both run at 20V, so the adapter changes the fitting and not the voltage. 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.

Why choose this adapter

• Your DeWalt 20V MAX battery and Porter Cable 20V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• 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.
• Covered by a 12-month warranty from the day it arrives.

DeWalt 20V MAX and Porter Cable 20V compatibility

It works in one direction only: DeWalt batteries powering Porter Cable tools. For the opposite pairing, see adapters that run on Porter Cable 20V batteries.

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

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge DeWalt or Porter Cable 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 DeWalt 20V MAX battery.
