DeWalt 20V to Makita 10.8V CXT (Post Style) Battery Adapter

Use your DeWalt 20V MAX batteries on Makita 10.8V CXT cordless tools, without buying into a second battery platform. 20V in, 10.8V out: the converter brings it down to what a fully charged 10.8V battery reads, rather than passing the higher voltage through. Built with a durable injection-molded ABS housing and pure copper contacts for steady current delivery. Fewer battery systems in the workshop, on the bench or in the van, and no extra chargers to find room for.

• Solid copper terminals, so less of the current is lost as heat.
• 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 Makita 10.8V CXT compatibility

It works in one direction only: DeWalt batteries powering Makita tools. For the opposite pairing, see adapters that run on Makita 10.8V CXT 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 Makita 10.8V CXT batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge DeWalt or Makita 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.
