The Festool 203892 5.5m H05 RN-F Plug-It Cable is the alternative solution to running out of power. Almost all Festool tools are equipped with the plug-it system. This allows you to utilise mains power should you battery run out. Alternatively, if the cable gets damaged, simply plug the new one into the machine, and keep on going. Instead of having to consider various different mains adaptors, one cable works with almost all Festool power tools.
