September 28, 2020 – Once attached to any M18 battery, the Milwaukee M18 Top-Off serves as a 175W power supply for personal devices and small electronics via its integrated AC 120V outlet, USB-C power delivery (PD) port and USB-A port.

Milwaukee insists every port on the Top-Off maintains full power, even when all are in use. The device comes with an attached metal rafter hook that can be extended to hang from carts, lumber or other jobsite materials. As would be expected, the M18 Top-Off is fully compatible with the entire M18 line-up, and comes with a 5-year warranty.
