The Milwaukee M18 TOP-OFF 175W Power Supply turns any M18 battery into a small portable outlet. It gives you one 120V AC outlet, a 45W USB-C PD port and a 2.4A USB-A port, so you can run or charge three devices at once. It weighs 0.8 lb and has a metal rafter hook to hang it from carts or lumber. It suits M18 owners who want power for a laptop, phone or small TV away from an outlet; rivals like the smaller TOP-OFF 150W unit trade the USB-C PD speed for a lower output, and generic battery inverters lack the hook and the M18 battery ecosystem.

The Milwaukee M18 TOP-OFF 175W Power Supply (model 2846-20) runs on any M18 battery and powers or recharges personal devices and small electronics. It has one AC 120V outlet, one USB-C PD port and one USB-A port, so up to three devices can charge at the same time without speed throttling.
The USB-C PD port delivers 45W. It can recharge a device from fully depleted to 80% capacity up to 75% faster than a conventional 5W wall charger. It suits laptops, cellphones, TVs and other small devices.
The compact, lightweight body has an attached metal rafter hook that extends to hang the unit from carts, lumber or other jobsite materials. This lets you set up a mobile workstation or keep electronics in sight when worksurface space is limited.
