18 V to 12 V Step-Down Converter for Milwaukee M18

This buck converter steps an 18 V or 20 V Milwaukee M18 battery down to a steady 12 V at up to 15 A, delivering 180 W with 95 % efficiency. It suits golf carts, power wheels, RC vehicles, LED lighting, cameras and DIY projects that need 12 V power from an M18 pack.

Check Battery Model and Load Before Ordering

The adapter fits Milwaukee M18 packs such as the 48-11-1812 through 48-11-1880 series. Verify that your device draws no more than 15 A at 12 V and that the battery can supply the required current; the converter will shut down on overcurrent, overvoltage, under-voltage, overheating or short circuit.

14 AWG Wires and Metal Housing for Daily Use

The unit uses 14 AWG leads rated for 105 °C and 600 V, with a rust-resistant metal plate that maintains solid contact. An integrated switch lets you cut power without removing the battery, and the protection circuitry stops transient spikes to protect both pack and load.

Questions about this item

What comes in the box and do I need to buy a Milwaukee M18 battery separately?

The converter includes 14 AWG input leads with a Milwaukee M18 mount, an integrated on/off switch and 12 V output terminals; a compatible M18 battery such as the 48-11-1820 or 48-11-1850 must be supplied by the user.

How do I decide which M18 battery capacity to use with the 180 W rating?

The unit draws up to 15 A at 12 V, so choose a battery that can sustain that current — higher amp-hour packs like the 48-11-1850 or 48-11-1860 will run longer than the 48-11-1812 or 48-11-1815.

What does the 180 W figure mean when I connect it to a golf-cart motor or LED lighting?

At 95 % efficiency the converter delivers a continuous 12 V 15 A (180 W) from an 18 V or 20 V M18 pack, with automatic shutdown for over-voltage, over-current, under-voltage, over-temperature or short-circuit.
