AEG 18V to Hikoki 18V Battery Adapter

Use your AEG 18V batteries on Hikoki 18V cordless tools, without buying into a second battery platform. Voltage is not the obstacle here — both sides are 18V. The socket is, and that is what this solves. 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 AEG 18V battery and Hikoki 18V 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.
• Covered by a 12-month warranty from the day it arrives.

AEG 18V and Hikoki 18V compatibility

It works in one direction only: AEG batteries powering Hikoki tools. For the opposite pairing, see adapters that run on Hikoki 18V batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the AEG 18V platform and that your tool takes Hikoki 18V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge AEG or Hikoki 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 AEG 18V battery.
