Bauer 20V to Porter Cable 20V Battery Adapter

Use your Bauer 20V batteries on Porter Cable 20V cordless tools, without buying into a second battery platform. Power passes straight through: Bauer 20V and Porter Cable 20V share the same 20V rating. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. Your existing batteries do more work, and there is no second ecosystem to buy into.

Why choose this adapter

• Your Bauer 20V 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.
• Made for the Bauer 20V batteries sold at Harbor Freight, so the fit is the one you already own.
• Covered by a 12-month warranty from the day it arrives.

Bauer 20V and Porter Cable 20V compatibility

It works in one direction only: Bauer 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 Bauer 20V 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 Bauer 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 Bauer 20V battery.
