Milwaukee M18 Battery Adapter – 18V to 12V with Integrated DC/DC Converter
Turn your Milwaukee 18V batteries into a portable 12V power supply!
Our specially developed battery adapter allows compatible Milwaukee M18 batteries to power suitable 12V electrical devices.
An integrated DC/DC converter reduces the battery voltage to a regulated 12V DC output, with a maximum output rating of 5A / 60W.
Ideal for suitable 12V water pumps, mobile workshop equipment, camping applications and custom electrical projects.
Portable Power Without a Separate 12V Battery
Conventional batteries can be heavy, require additional chargers and may be inconvenient to replace.
With this adapter, you can use existing Milwaukee M18 batteries and quickly exchange a discharged battery for a charged one.
This makes it particularly useful for applications requiring a flexible and easily replaceable power source.
Integrated 12V Voltage Converter
The integrated DC/DC converter reduces the voltage of the connected 18V battery to 12V DC.
- Output voltage: 12V DC
- Maximum output current: 5A
- Maximum output power: 60W
- Suitable for compatible 12V electrical devices
Connected devices must be designed for 12V DC operation. The maximum output rating must not be exceeded.
Flexible and Vibration-Resistant TPU Housing
The adapter housing is manufactured using 3D printing technology and TPU (thermoplastic polyurethane).
Thanks to its flexible properties, TPU is well suited to applications where vibration may occur, such as mobile equipment and vehicle-mounted systems.
Four Mounting Points for Secure Installation
The rear of the adapter features four mounting points, allowing the housing to be attached to a suitable mounting surface.
This is particularly useful when installing the adapter permanently near a water pump, inside a camper or as part of another mobile electrical system.

Important Information
Warning: Only suitable for compatible Milwaukee M18 18V batteries. Not suitable for Milwaukee 12V batteries!
We recommend using genuine Milwaukee batteries. Compatibility with third-party batteries cannot be guaranteed.
Only connect suitable 12V DC devices. Do not exceed the maximum output rating of 60W or 5A.
Electrical devices with motors, such as water pumps, may draw a higher startup current and must be checked for compatibility.
This adapter is not a battery charger. Batteries must be charged using a suitable charger.
Appropriate electrical protection and deep-discharge protection must be provided. Whether such protection is already integrated into the adapter should be verified before use.
Always connect electrical devices using the correct polarity and according to their electrical requirements.
