Bosch 18V GBA (Blue) and Parkside X20V compatibility

It works in one direction only: Bosch batteries powering Parkside tools. For the opposite pairing, see adapters that run on Parkside X20V batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Bosch 18V GBA (Blue) platform and that your tool takes Parkside X20V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Bosch or Parkside 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 Bosch 18V GBA (Blue) battery.
