Want to use the Reed Pump Stick but don't want to commit to a new battery platform? Don't stress! Use the Reed CPAPDEW 98140 adapter plate from Reed to adapt to your Dewalt batteries. The CPAPDEW is compatible with Dewalt 20 volt batteries that you use with the rest of your cordless tools. Simply buy the base tool (found here) without the extra batteries and charger along with this battery adapter plate and start pumping!
