Bauer 20V to WORX 20V PowerShare (Orange) Battery Adapter

Use your Bauer 20V batteries on WORX 20V PowerShare (Orange) cordless tools, without buying into a second battery platform. 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. Fewer battery systems in the workshop, on the bench or in the van, and no extra chargers to find room for.

Why choose this adapter

• Your Bauer 20V battery and WORX 20V PowerShare (Orange) 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 WORX 20V PowerShare (Orange) compatibility

It works in one direction only: Bauer batteries powering WORX tools. For the opposite pairing, see adapters that run on WORX 20V PowerShare (Orange) 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 WORX 20V PowerShare (Orange) batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Bauer or WORX 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.
